Better mattress support can lead to a better night's sleep. If your mattress does a poor job supporting you, you simply won't sleep as well as those that have a mattress that aligns the spine. These mattresses have been rated above average in support, but some had issues with how they felt for them.
Most reviewers find these mattresses to have fine edge support, which is welcomed for those that like to sit on the side of the bed. Those that are heavier may still experience some declining around the sides of the mattress.

Bowling Ball & Density Tests
The bowling ball test of even support is important to figure out if the mattress will provide a good surface to support the spine. These mattresses will provide a good amount of support overall, but there are a select few who may experience discomfort.
Mattresses with longevity will last between 7 - 12 years based on the materials in them. Generally, foam mattresses will be less durable, and coils mattresses that are well made will last longer.

Some have found comfort for the long term, but others have had complaints.
This mattress is incredibly comfortable and we have been sleeping great since we got it! The pillows are awesome, too! So satisfied!View More Reviews
My experience with this latex mattress has been mixed. I purchased in February 2017. I do love the natural feature of the latex layers, mattress, cover and pad! And, the quality is great. However, my experience thus far with regard to comfort and support levels, a good quality memory foam or innerspring mattress will work too. For the extra money, I have not experienced the comfort and support I thought I might. I will keep switching the layer around to see if I find a better fit.
I love my mattress! It is comfortable and allows me to get a great night of sleep every night, especially since I was able to customize the four layers to find the best combination for me. I also have FSF pillows, and I take them with me on trips whenever possible! Other pillows and mattresses do not compare with FSF.
Superb mattress; outstanding customer support. Very happy!
I absolutely love my new mattress! I've always been a terrible sleeper since I sleep on my side and wake up with a sore neck and lots of aches and pains. Since I've started sleeping on this mattress, I'm still able to sleep on my side but no more pain! I also use the Latex pillows that are equally as amazing! I travel a lot for work and sleep in lots of different hotel beds, and never realized how much I cherish my new mattress and pillow until I got my Foam Sweet Foam bed! HIGHLY recommended!! Customer service and the delivery and set up set themselves above the rest! Thanks Foam Sweet Foam!
My husband and I love our mattress! It has to be the most comfortable bed we've ever slept on! We're never going back to regular mattresses. Latex is amazing, it doesn't run hot, or lose shape over time. I fall asleep faster, stay asleep longer, and dont wake up with aches. Thanks again, Foam Sweet Foam!
I have a huge complaint about the mattress which I bought from you over 2 years ago. It is hard to get up in the morning! It used to be easy to get up in the morning because it was more painful (Fibromyalgia) to stay in bed. Now it is the coziest, most restful, almost pain free place to be. From the beginning there was a dramatic improvement in my sleep & a significant reduction in the level of Fibromyalgia pain throughout the day. My health is still improving.
Love my Foam Sweet Foam Mattress
After many restless nights on our old innerspring mattress, my wife and I decided it was time for a new mattress. I began my online research and found Foam Sweet Foam’s website and began reading all of the details. I really liked what I saw at FSF as their site had way more information than the others. The Mattress Underground showed that FSF had a very good reputation as well. So I contacted FSF by email and began discussions with Heidi.
I’m a big guy 5’11” 320 lbs. (I’m a side sleeper, and my wife is a back sleeper). FSF came up with a split queen with the correct layers to accommodate both of us. We made the purchase and received our mattress, cover, and pad in May 2017 and have slept much better since.
The prices offered by Foam Sweet Foam were less than the nearest retail store (90mi. away) that we visited that had latex mattresses. With FSF we knew what was in the layers we were getting. Also, the FSF guarantee gave us confidence in making an online purchase of this amount.
We feel like Goldilocks, 4 mattresses in 18 months. Finally, we found the perfect one! Before purchasing this one, I did a lot of research, spending hours sifting through the different types of mattresses and companies. After narrowing it down to latex, I called several companies asking them questions and advice. I came across Foam Sweet Foam and loved their approach. No pressure, never pushy and very informative. Just good advice and suggestions on what might be a good fit. We loved the concept of the layers. We purchased a 13 inch Split King, his side a little firmer than mine. We can’t begin to tell you how much we are in love with our new mattresses! No heat issues for me and we are loving that little bounce instead of that sinking feeling! Also purchased the mattress pads and pillows..Oh, the pillows! We highly recommend Foam Sweet Foam. Thank you for finally giving us find a good nights rest!
I recently purchased a four layer talalay/dunlop latex mattress and absolutely love it! After several months of indecision, I decided to try FSF. They were extremely knowledgable and accurately suggested which layer combination would be most comfortable (soft, med, firm, x firm) for my height (5' 8") and weight (135 lbs). I highly recommend them. I could not beat the great price either--buying direct saved my thousands of dollars. My order arrived in perfect condition (CA to FL) and took just a few minutes to setup. Thank you FSF!
We’ve had the mattress for about 6 months now and love it. After years of sleeping on a memory foam topper this is a real treat. I had no idea there could be such a difference. Love the way the latex sinks in and bounces back when I move.
Thank you and Heidi so much for answering my endless questions with such patience. Your recommended layers are perfect for me and my husband and as a night owl I now look forward to going to sleep.
Thanks again for everything!
Update May 2017
Still love the mattress! It is the most comfortable mattress I have ever slept on!
For the past 3.5 years I would wake up in the middle of most nights with terrible aches in my left leg and hip - sometimes it would keep me up for 2-3 hours. A friend of mine loved her mattress from FSF and told me they were online order only. After another sleepless night I told myself, "I have to do something about this." I called Foam Sweet Foam and on a leap of faith, I talked to their customer service and they helped me choose my layers: Talalay Soft, Talalay Medium, Talalay Firm, Talalay XFirm and it's PERFECT for me. Since my first night sleeping on this bed (since July 2015) I have not woken up with leg pain and my husband says it's the best sleep he has had. For me, going to bed now is a joy not a dread. I can't say enough good things about this mattress and company. If you’re not sure what is the right combination for you, call them and they will walk you through it!
WOW, WOW, WOW, cannot say enough good things about them. Awesome, wonderful, comfortable mattress layers. I have major back issues and multiple failed surgeries so comfort is a must. Customer service is unbeatable. I am so pleased that we found this company. Above and beyond. Thank you Scott and Heidi
This Mattress is the most comfortable mattress I've ever owned. I'm very happy with it. I really like the multiple layer system because it gives you the option to swap the layers around until you find the perfect firmness. I'm the kind of person who will lay on a bed that is super soft and think I love it only to realize a few weeks later that I need more support. Once I swapped the firmer layer to the top it was perfect!
I am in love with our 16" king mattress! I'm glad I called for advice on the best firmness for each layer, or we'd have ordered too soft.
My only small negative is the layers are a couple of inches longer than our mattress base so we need an oversized top sheet to allow enough fabric to be tucked in at the foot of the bed.
I generally love soft beds for the cloud-like feel, but my bed became too soft for me which led to lower back problems. The first night I slept on my new mattress, I woke up with no more back pain. It was also the first night in months that I slept through. It is firm for support but soft enough to keep me happy. I just sink it. I am so happy with my new bed!
I LOVE my mattress! I've had it for several years now and it still looks brand new. I'm very satisfied and will definitely purchase again!!
I love our mattress! It was very comfortable from the start and now we have had it for a full year and it still feels brand new. It has not made holes where we lay at all! My husband and I both sleep great on it, and always look forward to coming back to our own bed after vacation! We highly recommend this bed!!
This mattress has given me the best sleep of my life. Not only is my mattress soft but it is so supportive. I find it hard to sleep anywhere else and when I am on vacation I find myself dreaming of going home to sleep on my mattress. Thank you foam sweet foam for revolutionizing the way I sleep.
My husband and I were looking to replace our mattress and we couldn't be happier with Foam Sweet Foam. Super comfy but firm and supportive! No coils, no harsh chemicals, and great customer service. Each layer came individually packaged and assembly was pretty easy to figure out. We will never go back to coil spring mattress again! Thank you Foam Sweet Foam, we love our mattress!
My wife and I were looking for a new mattress, and couldn't have made a better choice! The layers of foam were easy to stack, and we really like the idea that we can swap layers around if we decide we want a softer mattress in the future. We have been getting great sleep. We love it so much that we contacted Foam Sweet Foam, and were able to order custom sized mattresses for our camper! This has vastly improved our sleep while camping. Thank you so much Foam Sweet Foam!
Wow! The mattress arrived with each layer compressed and bagged. It was easy to assemble the mattress layers. We are enjoying very comfortable nights of rest.
I like it, I dont love it. The comfort is great, I sleep well every night. Its firm but soft. It gives the support where I need which is a good thing. Just know that this bed comes in multiple parts and each part is heavy. If you are rich enough then have a white glove company set it up for you, or endure the set up once and don't move the bed again.
Our Foam Sweet Foam mattress is wonderful! We recently had several guests in our home sleeping on our mattress and they all told us the next morning what a great mattress it was to sleep on. We even moved it across the country and it held up incredibly well, still giving us a great night of sleep each night. I also LOVE the latex pillows we got with our mattress. I try to take it with me whenever I travel. I've never been so attached to a pillow in my life!
Last night was my first night on the new mattress after buying all the sheets and stuff at Ikea!! It was like sleeping on a cloud, wrapped in cotton candy, with vanilla bean aroma in the air, with pancakes and bacon ready for me in the morning! Hahaha. I love it!
We purchased our mattress from foam sweet foam 3 years ago. I can't express enough, that this is the best mattress I've ever slept on. It's still as good as new, and I rest assured I won't have to think about buying another for decades. My wife and I both like a firmer mattress, so we got two layers of extra firm, and one firm. Whenever we have to sleep somewhere else, we're always disappointed, and wish we could take our mattress with us, we love it so much!
FINALLY after MONTHS of research, I decided to purchase a latex mattress. Then....MORE research deciding which company to purchase it from. It was extremely hard for me to spend this much money on a product I had not SEEN much less laid on! Even though I made numerous phone calls to FSF before I finally purchased, they were always patient, addressed each question and concern with knowledge and without any pressure for me to order. Taking factors of my husband’s and my height/weight/sleeping positions and individual pains into account, they suggested a 4 layer bed with each layer PERFECTLY suited for our specific needs. Our mattress is more comfortable than we dared hope for!! Thanks FSF AND to Phoenix of “The Mattress Underground.” Without his sharing years of his own research on ALL types of mattresses, I’m afraid I would STILL be trying to make a mattress decision, instead of sleeping blissfully every night. We wake up each morning rested and without pain.
We've had our 3 layer talalay mattress since 2011. It's been great for all of these years. No sagging. Recently, I contacted customer service for replacing the mattress cover that got damaged due to hurricane Irma. They were very prompt with their answer and I'm very satisfied with their stellar services.
I've had my mattress for three months now and absolutely love it. I chose a firm/firm (both talalay) combination as I wanted firm, but needed a lower profile. It is nicely firm, yet still has some give to it. I also like that it had very little odor. I'm on the lighter side (about 140 pounds), so this choice worked just fine for me. One thing that stood out in the purchase process was a call from foam sweet foam. My choice of mattress firmness levels was not typical. They called to discuss this to help make sure that I was making the best choice. While I stayed with my initial choice, I am glad they wanted to make sure that I would enjoy my mattress.
I also purchased the mattress pad. It is nice and high quality. That said, I really like the feel of the mattress cover and wish the pad were just a removable version of it. Assembly was pretty easy. I had a minor issues with the zipper at first; a slightly more heavy duty zipper would make it even better and easier to set up.
I would highly recommend Foam Sweet Foam as a company. Heidi was one the best customer support people I have ever dealt with, she did everything to help me and stuck by me. Great company!!!
We have had our 13 inch king size bed for about 2 months and absolutely love it! We went with Soft Talalay, Medium Talalay, Firm Dunlop, X Firm Dunlop for our layers. It is perfect for us - so supportive, yet not hard. Latex is the only way to go and we were very happy with the Foam Sweet Foam Service! We went to a few stores selling latex mattresses and were shocked at the prices. FSF offers excellent value. Highly recommend! We are die hard Latex converts!!
We've had our 13" split king (on an adjustable frame) for a year now and couldn't be happier! Foam Sweet Foam made shopping easy and, although it was a substantial purchase and we'd never tried a latex mattress, it sounded perfect and has exceeded our expectations. I'll never buy another mattress with springs or memory foam! We customized our firmnesses--hers is slightly softer--and even though she has some minor medical problems, we're both having the best sleep of our lives. Thanks!
I've been meaning to write this for some time to let you know how pleased we are with our mattress. I don't frequently write reviews, but I do rely on them when making a purchase. I like to know how a product is performing over time. We purchased our mattress three years ago, and are nothing but pleased with it. We ordered a three-layer: soft Talalay, medium Dunlop, firm Dunlop. We were interested latex because we are not fans of the chemicals used in a conventional mattress. We drove 1.5 hours to the showroom of a different dealer, where they had the same mattress for significantly more money. We were impressed with latex, but overwhelmed by the cost, so we looked online. It was a big investment, but we have never regretted it. It was one of the best large purchases we have made and is undoubtedly the one we use the most! It is, without a doubt, the most comfortable bed I've ever slept in. Thanks Foam Sweet Foam for making out nights much more comfortable.
Bought a 16" King-sized after years of research. The first night on it was so comfortable & supportive of joints & back issues. Now we cant stay out of it. Sleeping too much! Hubs snores much less too. Dogs went to sleep instantly. Personal & great service! Simple to put together after watching the video a couple times. We're older and short but this was easy for us because of the layers. 9 stars!!
We've had our 16" king sized mattress for approx 3 years now. The mattress is comfortable & holding up well. My only thing is the movement/motion I feel when you have a 300lb partner who tosses & turns all night. It is definitely not like a temperpedic if that is what you are looking for...that being said, I have also owned a temperpedic like mattress & had joint pain from feeling "stuck" in the mattress & not being able to turn over easily. Overall, great mattress if motion doesn't bother you. Sheets thick enough for the 16" are near impossible to find & be warned, this thing is HEAVY once put together!
We received your 4 layered custom mattress in July. I didn't know at first if I would like it. It's now almost October and the best thing I can say to a skeptical customer is to give it a few months like we did. I wouldn't trade this bed for anything in the world now. It's different but it's amazing. No more pressure points. No more sinking into the mattress. Perfection. Restful Sleep. Done. :)
We are getting ready to purchase our 3rd mattress from FSF. We bought our king 4 layer mattress 3 years ago, then one for our son, and now one for the guest room. After 3 years ours is every bit as wonderful as it was when we first got it. We literally can’t wait to get home from a trip so we can sleep in our bed. No more neck and hip aches. Yay!
Foam Sweet Foam (FSF) is an excellent mattress resource. From the prompt and professional response to my initial questions, to the FAST and free delivery, to a good nights sleep on the new bed -- every step was a pleasure thanks to the folks at FSF. I appreciate the great recommendadions for the layers and the ease of set-up (2-person job). I recommend FSF without reservation!
We always thought that if we spent more we would get more, but we got tired of a well known brand that costs $3K that became uncomfortable and developed a sink-hole - with that last mattress, it lasted only a year. So I did the research, and learned that it was all about the materials. FSF uses the best foam in the industry, and provides the ability to customize the layers and adjust. So we went ahead and ordered a 13" King, knowing that we could adjust it if necessary. It has been almost a year on our FSF mattress, and I can confirm that it is the best mattress that I have ever slept on. Now, I look forward to going to bed because it is so comfortable. Having a Talalay top layer is key for us - it's supremely comfortable to have that 'bounce' on top, and the solid Dunlap base layers below. When our daughter moves out, we will buy a FSF mattress for her. We don't want to get her one before then, because then she might never leave!
Absolutely fantastic experiences. From ordering, to delivery, to outstanding sleep.....bought two mattresses a few years ago and am still enjoying perfection. This is an awesome product and you have to sleep on one of these mattresses to fully understand how comfortable they are! Contacting via phone for assistance or questions is about as friendly and helpful and professional as imaginable.
This mattress is comfy! It's not too firm and not too soft. I love it! I was a little nervous before I bought it because the price is so low. Once I went in the store and tested it out, I knew I was going to get my monies worth. Granted I've only had it for about a week now, even my boyfriend has confirmed it's super comfortale. Get it while it's on sale.View More Reviews
I bought the twin mattress and much to my dismay there was about a 4 inch gap between the mattress and my bed frame. After measuring the mattress I realized it was only 36 inches wide, not the standard of 39 inches (despite the website listing it as 39 inches wide). I finally got a hold of the manufacturer and they said that their twins are "intended" to be 38 inches wide but that each one can differ by up to two inches. So you're basically left with a mini-twin. I will be returning this.
It's pretty comfy for the price but honestly I could have gotten cheaper at another matress store, definitely shop around more. It's not very thick and the euro top seems like it will be flattened very easily I give it maybe a year before it starts losing its comfort completely
My first set of guests found this to be very comfortable. I slept in the guest room to try it out and found it very comfortable. I am very pleased with this purchase and will purchase future items.
Nice product at the right price. My child needed a mattress for a new college apartment. We saw many options and even ran into a manufacturers rep at the store who helped us with good advice. As usual, the experience was great
love this mattress very comfortable the never disappoint
Great price and such an amazing mattress. The level of comfort is undeniable. I'm very happy with this product and would recommend it in a heartbeat.
This mattress was purchased for a bedroom that is only used for guests and when child is home from college. The mattress is very comfortable and the price is perfect for this situation. We have had it about a week and my kid loves it, it's 12:20 pm now as I write this review and she is still sleeping.
Buying this mattress was an amazing investment. Such a comfortable bed to sleep on and the service and delivery was very prompt and professional.
Very happy with what I bought slept like a baby. The delivery guys came set it up fast. Very happy with the service.
My husband and I are sleeping so much better since purchasing this mattress. It's not too firm or too soft, so you get support without feeling like you're sleeping on a board.
We love our new Mattress! The comfort and quality is unbelievable and for what we paid for it...we just love it!!
I purchased two of these mattress for my boys, without them being there to try them, and they just love it. They said it's so comfortable that it just conforms to their bodies. Mind you my 15 year old is 262lbs and said the bed is like a giant blanket. So hats off for a great product at a reasonable price...
I recently stayed in a bed in a breakfast in Maine--and loved the mattress I slept on. (I've got neck and shoulder issues to the mattress is often crucial.) I found a similar King Koil mattress and Raymour and Flanigan. The price was right; the delivery was prompt. "For this relief much thanks." Happy with my purchse: feels good!
When choosing a bed we needed a firm mattress with back support for me but yet some cushioning for my husband and the King Koil Perfect Response Elite Lakeside Pillowtop was "the perfect" choice. Very pleased with our decision and we even received next day FREE delivery - very nice!
I love my new mattress -and the service that came with it.
The bed is great. It came when they said it would and the sales person was wonderful in working with our family.
Bought this for my guest bedroom and it was given an A plus By my first guest. She couldn't believe it was a firm mattress. Would highly recommend.
WE NEEDED A FIRM MATTRESS AND THIS IS PERFECT! NOT ONLY IS IT EXACTLY WHAT WE WANTED THE INSTALLATION WAS WONDERFUL. WE NEEDED SLATS FOR SUPPORT AND THE DELIVERING TECHS DID IT ALL WITH NO PROBLEM. SALES PERSON WAS WELL INFORMED AND ANSWERED ALL OF OUR QUESTIONS. FLO L
I have a California King Mattress and it is the best.... I was not sure of down sizing to a Queen Mattress, but I must say that it was the best choice I love the way my body rest and the best part is that my husband and I are know closer....
THE MATTRESS AN BOX SPRING I PURCHASED WAS JUST EXCELLENT. ITS MEETS ALL MY STANDARDS FOR COMFORT .THE SALES PEOPLE WERE JUST GREAT HELPING ME FIND THE RIGHT ONE . I HIGHLY RECOMMEND MY CHOICE.AND THE STORE LOCATION ON CROPSEY AVENUE
It's hard to get out of bed after sleeping on this very comfortable mattress. You look forward to relaxing at the end of the day. I like it very much. Keep in mind, coupled with the box spring, it is very high. Can't go wrong with this one, unless you like it extremely firm. It has the right kind of firm but soft too.
Very happy with our purchase! Bed is comfortable. Not too firm, not too soft. Great quality for a great price!
The mattress is very comfortable. It's the best sleep I've had in a long time. It is a 5 star hotel quality mattress. I'm in love. I must stress that the hubby that works at night and have Insomnia also agreed that his sleep has been much better. Thumb's up.
I absolutely love my new bed. Best experience it's comfortable for my back after I come home from work cause I work 19 hours of the day doing labor and I just needed a new way to sleep. This is one of the most comfortable beds I've ever slept in and I highly recommend it to everyone.
The store was great the product was well priced and it was a convenient purchase. Loved the salesmen [Associate name removed].
This mattress has just enough firmness topped with a pillow top that has just enough softness! The price is perfect and the customer service was out of this world. No one trying to force me to the most expensive products in the store.
I am very much enjoying my new mattress. I was afraid it might be too soft but I'm glad I went with the softer mattress over the more firm mattress. While this is soft, it is still very supportive. This mattress is great quality for a good price.
great mattress sleep like a baby love it so much it is great
Best decision i made for my son he loves his new bed. Raymour and flanigan alway have good quality furniture which last a long time. I know when i shop with them im getting good stuff.
I needed a mattress for my fathers spare bedroom so I had a place to sleep when I visited. I didn't want to spend a lot but I wanted something that was nice and comfortable. This mattress is it! I have slept great when visiting him now and the Sales associate Tom P. in Clifton Park listened to my needs and took care of everything! Thank you Tom!
very comfortable but still with support!! Very happy!!
This mattress was purchased for a guest room and has only been slept on once with a report that is was very comfortable. The salesman was very helpful and polite. The delivery team were very helpful and delivered quite timely
I really like this mattress. It's really comfortable and it feels like I'm sleeping on a cloud.
My old mattress was still in good looking shape, but had outlasted the years I needed an extra firm mattress. My new King Koil plush is so comfortable, I sleep right through the night. Both my husband and I are well pleased with this purchase.
Mattress is unbelievably comfortable. My wife and I love it so much.
So far so good! Great price for the quality. I'll write another review after about a month or so
I am so happy with my purchase. I haven't slept this well in a long time. I definitely Recommend this mattress. The salesman was very knowledgeable and he listened to my needs.
I am very happy with my king coil mattress purchase. In the past I have always bought Sealy's. It is very comfortable and I am happy with it. Also the service at the store and the delivery was very good. I am also very happy with the guarantee on the mattress.
Mattress after the first night of sleep had a indentation in it already. Was or is not as comfortable as I expected.
