Mattress support is extremely important to a good night sleep. These mattresses are above average in their supportiveness. It is important to note for those that suffer with spine alignment or tossing and turning. Most customers describe these mattresses as providing good support in the short term.

Mattresses that have good durability ratings last between 7 - 12 years based on the materials used. Mattresses with springs tend to last longer if they are well made than foam mattresses -- though this is not always the case. That said, mattresses that don't have good durability will start sagging much quicker no matter the materials. Sleepers have mixed things to say about these mattresses. Some report lasting comfort, but others report quicker than average degrading.
If you are considering one of these mattresses, make sure to read on for more information. Sadly, they don't get the best reception from all customers. Some spoke high praise about their experience, but many others had issues with the feel.
A supportive mattress isn't always a very firm mattress. Support is great if it aligns the spine and leads to a healthy night's sleep. Unfortunately, these mattresses have some mixed reception when it comes to support. Most find that they provide a good amount of support at the beginning, but some have had issues with support over the long term.
For folks that sit or lay on the edge of their mattress, edge support is essential. Overall, these mattresses do a good job at first with support at the edge, but some had complaints that edge support wasn't all it could be long term.
Mattresses with lasting comfort are amazing, but not always easy to find. These mattresses are reported by customers to be not as durable as others. That said, some customers may find their mattress lasts longer than average, while other customers may have much faster discomfort. If you are a heavier individual, read up on your options because you may be at a higher risk for durability issues from some mattresses.
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.
Outstanding mattress at an unbeatable price. Mattress Firm wanted $1k for the same exact mattress!View More Reviews
This mattress felt great at first but after only 1 year started to sag on both sides, leaving a "hill" in the middle.
Now we are having back problems and so are replacing it after only a little more than a year. This is a horrible investment,
don't make this mistake.
Way too soft!!
Mattress is ok for few years but when it does go back, forget about the 10yrs warranty. Simmons will no honor it.. they will try to charge you as much or more for "upgrading the mattress" with no warranty on the replacement! I have filed complaints with BBB but they don't care.
Please file complaints if you have had any warranty issues so they are force to take of the customers!
Wished it was thicker
We just received this mattress today, and it is TERRIBLE! I am writing this review at 1:30am because I can't sleep on it. I have given up and am now lying on a foam topper placed on the bedroom floor, and I am much more comfortable here on the floor than I was in the bed.
The fabric on the mattress is stiff and of very low quality. This shouldn't be a problem because it's covered with a mattress pad and sheets anyway, but it still doesn't "give" for that plush feel. You sink into the mattress, which could be good, except you are met with hard springs and awful pressure points. My husband, a back sleeper, is already having terrible back pains after just a few hours. I'm a side-sleeper, and my shoulder and hip are killing me. I know they say a mattress needs time to settle, but I can't tolerate this bed for a few hours, much less a whole night. I will be returning this mattress.
The cheapest made mattress we have ever purchased. I have now had 2 of these mattresses, the first was ripped and sagged in the middle right out of the package. They (nationwide retailer) replaced it with another and it is as bad, if not worse. It squeaks so bad and is so cheap. I paid over $1,300 for a king set and it is completely useless to us. It makes so much noise and racket every time you move. I will never buy anything with the Beautyrest name.
This is the Worst worst worst bed ever!!!!!
The worst purchase we ever made. If you have back or hip issue potential, this bed will bring it out! I hate this miserable, awful bed!
If Stephen King were to write about a pain inflicting bed, this bed would be it!!!
Beautiful comfortable bed delivered thru Amazon just as easily as ordering a small item
Delivered fast and easily. We are quite happy. Excellent quality !
Outstanding mattress at an unbeatable price. Mattress Firm wanted $1k for the same exact mattress!
Had this restored spirits five years.the last three years were hell. My husband wouldn’ Sleep on it. Contacted Simmons for inspection and replacement. No go. I have spent weeks reading reviews. I am sleeping on this any longer. Moved to guest room until I find new mattress. I will never buy another beauty rest.
Thought I ordered the plush mattress, but received the firm. Trying to adjust to this mattress. Good price and good quality.
I could not be happier with the pillow top mattress that I recently purchased. The pillow top seems to help me sleep better and is better for me to sleep on since I have arthritis. The mattress fabric is of excellent quality.
This mattress is nice and comfortable. Good deal. I picked this mattress out online. I've never bought a mattress online before. Fortunately, it worked out. Good choice.
The mattress is nice and firm, pillow top just as I ordered. I was very surprised at the excellent quality of the mattress. Have got no response to the advertised gift card. It was supposedly mailed separately 2 weeks ago
I tried many mattresses in 4 different stores one Saturday and most were fine but as soon as I lay on this Simmons Beautyrest, something felt different. I walked around and tried a few more then came back to the Beautyrest. I knew it was the one - perfect pillow top yet firm as I like it. No more sleepless, tossing and turning nights!
Purchased the Silver but only kept it 3 weeks. Was good the first week but by the second week started to break down. By the third week it was squishy and made my back worse. If you have a bad back don't buy a pillow top. They tell me now that I am returning the mattress. Penney's does not refund your money so am having to buy a different mattress. Originally told I had up to 100 days but that is no longer true, it is now 48 hours. Who can tell if a mattress is right for you in 48 hours. Wish I had not purchased my mattress from Penney's. Buyer beware.
VERY DISAPPOINTED. NOT WHAT I EXPECTED. THIS QUEEN SIZE MATTRESS COULD NOT POSSIBLY BE WORTH APPROXIMATELY 1800.00(I DID NOT PAY THIS PRICE) BUT IT'S NOT WORTH THAT PRICE! JUST NOT SATISFIED. SEEMS CHEAP, NOT TOO COMFORTABLE. DOES NOT FEEL LIKE YOU'RE SLEEPING ON A CLOUD, NO WAY! I PURCHASED ONLINE, BIG MISTAKE! GO TO STORE PERSONALLY TO CHOOSE YOUR MATTRESS.
I think this is an excellent mattress. The only thing was the delay in getting the mattress whic paritally was my fault since I ordered the wrong one at first. Oerall I am very pleased with it!
I thought it would be a little softer on the top but I still sleep great.
This product is not as firm as I expected. I was hoping it would get better as i get used to with it but have not seen the result as of yet.
It seems to be very well made; movement dampening is good. If you want something firm, this probably isn't what you want. I am a stomach sleeper and the plush doesn't really support the arch of your back.
This bed is very comfortable. It's like sleeping on a cloud. Great buy.
Mattress feels like its years old already with height changes that make it uncomfortable
Most mattress start out great, the real test is over time. We hope it last years as it should with out sagging or breaking down
I love this mattress! Quality is great and the opportunity to use coupons and earn rewards is awesome! The company that delivered the mattress was great also.
I was looking for a firm mattress, and found it in this Simmons Beautyrest Silver Snowhaven Luxury Firm Mattress! It's A Five Star Rated Bed, That I Guarantee Will Give You A Five Star Night's Sleep!!
Problems with delivery, didn't get it until over a month after ordering even though we're home 4 days out of the week. After only a couple of months with the new mattress, it already has 2 slightly sunken spots where we lay, and we are not overweight people. I've heard that Simmons makes a better mattress if you are willing to pay a lot more, but this apparently isn't one of those.
previous mattress was a Beautyrest plush king. Wanted a little more firmness but full firm was too much. The luxury firm was just right. Took a week or so to get used to the extra firmness but now we love it. Also, this mattress is nice and thick so it works well on a platform style frame without the need for box springs.
For the first time in months I slept like a baby the very first night I got this mattress. Firm yet extremely comfortable. I just love it. I tried a Saatva brand luxury firm mattress and it was terrible. I had to come back to Beautyrest and I'm glad I did.
The salesman was so easy to work with. And the delivery men were great.
This is my first bed purchase without actually trying the specific bed first, I tried a few out at the local store and then saw this described online. I was nervous but the product is actually good. Only complaint is it took over two weeks for delivery
This mattress is great buy. I originally planned to get a tempur pedic. I then switched to a Stearns and Foster. In the end this was the best mattress at a great a price. It was more in my budget.
We finally chose this new mattress after much research. We were scared of so many choices available, but not a lot of positive reviews on most of them. With backaches every morning for my husband for awhile now, & now mine starting to hurt, we knew it was time to take the leap & buy a new one. I was shopping at Penney's for towels while my husband waited in car, when I seen the mattress sale. So I went & got him & made him lay on a few. He chose this one & the very first night he slept like a baby, & has ever since. We both wake up with no soreness already. It is a tall mattress & we bought a new box spring as well, so we have to slide down out of bed. But we love the height of it right now. And maybe as we get older we'll have to get a step on each side, or go with the standard bed frame. We have a lovely vintage oak bed with side rails, so both pieces had to sit on that. So it is tall now! So if you need lower, suggest buying just the mattress & sitting it on the plywood (as suggested for warranty)..I would still like both pieces even if I had the lower frame. So we love it & would recommend it. Pretty too! Love the navy blue sides.
It is so difficult to choose a mattress that you have confidence in, but this mattress is great! It is firm but well cushioned. It is also beautiful. The excellent delivery and set-up service is also appreciated. Virginia Jones
My daughter loves her new mattress. She actually took her thousand stuffed animals off the bed so she could really enjoy it.
This bed is very comfortable, I would recommend to anyone.
simple only need 1 no need for box spring and comfort is amazing .. fits to you.. feeling someone else kicking is very mim.
Price was great, had to wait on delivery, but received when quoted by very nice employees an they removed old one. Mattress is firm but must be covered by mattress cover for warranty i believe.
