Reviews are a great way to distill the benefits and drawbacks to a mattress. However, it can be a difficult thing to stay focused on after reading hundreds of reviews. Based on recent reviews and overall customer sentiment, these mattresses have some mixed emotions. Some sleepers are extremely comfortable, but others aren't as happy.
You may think supportive mattresses are always firm mattresses, but when we write about support, we are describing mattresses that support the back independent of firmness. These mattresses are well rated for their supportiveness for the average customer, but rarely, some customers don't always like the feel.
These mattresses have good support along the edges, which ideal for those that sit on the side of the bed or enjoy laying on the edge of the mattress.
Bowling Ball & Density Tests
By resting a bowling ball on the mattress, you can measure how even a mattress is in terms of support. These mattresses will provide a good amount of support overall, but some folks rarely may experience some discomfort.
Finding a mattress that is highly durable can save you loads of money. But, these days, everything from what you wear to where you sleep are degrading faster. Customers have mixed feelings about the durability of these mattresses. Each bed is different so it may last years for you, but others may not be so lucky. Do some additional research on your mattress choice to make sure it fits with your body.
If you are considering this brand, take a look below for more from customers Sadly, not all customers review them well overall. Some customers were elated by their selection, but others felt let-down overall.
Support isn't equal to firmness. Support is great if it aligns the spine and leads to a healthy night's sleep. Sadly, some customers don't find these mattresses to have great support. Most find the mattress to be comfortable at the beginning, but some folks felt like support was lacking over the long term.
For those that sit on the edge of their mattress in the morning, edge support is very important. For most folks, these mattresses do a good job with edge support at the beginning, but some had complaints that edge support wasn't all it could be long term.
Sadly, not everyone rates these mattresses well for longevity. While some sleepers reported lasting comfort, others have experienced quicker issues than average. Make sure to take a look at the specifications, warranty, and reviews before buying.
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.
I did a lot of research before buying this mattress. The deciding factor was the recommendation of Consumer Reports. When I first received this mattress, in a square box, I was soooo disappointed and upset. I attempted to return it before opening it, but realized how expensive shipping would be. I returned to the website and their were no reviews but I searched some other mattresses with the same features and price points and discovered that it would, when unfolded, rise to it's full 12 inches and it did indeed have cloth covered coils (innersprings). It Did rise, and then some. I think it's about 13". Very comfortable, everything Consumer Reports said it would be. It's a little firmer than I would like it to be. It's not hard by any means, in fact it's quite comfortable and very good for my husband's back, he likes it a little firmer than I. after putting a good quilted mattress cover on, it added just the amount of plush and squish I love. I get a good night's sleep and wake with no stiffness or aches. I really like it.View More Reviews
Excelent matress, I wasn't sure to get it for my daughter since it didn't have any reviews but after a month of using it, she loves it, firm but comfortable; stays cool and no more joint pain.
We bought this mattress 2 3/4 years ago and I've been having chronic severe back pain for over a year. I had noticed that the bed definitely sinks in the middle when I lay on it and I'm a hundred and fifty pounds. We've only had this mattress for going on 2 years & 9 months. We loved it at first, until the past year. I didn't attribute my back pain to the mattress until I slept somewhere else and my back pain was considerably better. Everyday when I wake up after sleeping on this mattress my back hurts more than it does all day. My boyfriend has been sleeping in the basement on the couch because of his work shift for the past 4 months. When he sleeps on his mattress on the weekend he says his back hurts too. I just submitted a warranty claim, but have a bad feeling that I'm going to get the runaround from the reviews that I've read.
This matress is inches of metal coil and 4 inches of foundation nothing like I was expecting at all
My old mattress was very soft, in comparison this one is a rock, but I don't wake with the same sore spots. I have arthritis through out my back, shoulders, hips, etc but I'm sleeping better with this Sealy.
1 year later and I would certainly buy this mattress again.
Mattress is about 1yr 4m old and is terrible! It's well worn and sagging where I sleep and the amount of heat the 'cooling gel' holds in is ridiculous! I sweat all night long and wake up drenched. I wash the sheets almost every day now. I don't know what we were thinking when buying a foam mattress. When you squish foam it seals up all the holes in the foam eliminating it's availability to breathe! No brainier if we would have thought about it. Skip the foam it's not worth it!
Was worried that it was to good to be true.not a single thing wrong with it and it's absolutely wonderful to sleep on.saved us over a thousand dollars.
I bought this bed from another place and thought I would give it another review to help others out. First off I'm a bigger guy who is a furnace in bed with lower back probIems. I spent a month in the bed to give it a chance but ultimately had to take it back. It was soft enough to be comfortable and fall asleep in easily. Around 3-4hrs in I would feel my back slowly be unsupported and I would bottom out to the foam base layer due to my weight and the heat I put off would cause it to soften. I noticed though before my back would be unsupported I would sleep deeper and easier. My fiance is a belly sleeper and the softening would cause her minor back aches but she had liked the softness and comfort too. The bed felt as warm or a bit warmer as a spring mattress with a topper on it but a lot less hotter than a memory foam without gel. There wasn't too much off gassing. Overall construction was good but felt like this was for a lighter, cooler person.
Love it so far.I've had it for a few days and wish i would have done it a bit sooner.maybe is just me coming off an old futon 😝 but it's definatly plush but still firm
If I could give this matress 0 stars I would. After one month I noticed a moldy smell around my bed, I pulled my matress cover to find the smell coming from all over the matress. It's not chemical, think mold dish sponge. It's also sinking by bout 1/2 an inch, I weigh 160 lbs, that's after 1 month.
You can assume that any good sealy review is a plant/fake review. sealy is a trash company that makes trash products. I'm out $550, have no bed to sleep on, and couldn't be more furious. BUYER BEWARE!
I am 6'3'' and weigh 220 pounds. I prefer a firm mattress and have only slept on box springs my whole life. I am a side sleeper exclusively. I went to 2 separate mattress retailers and laid on every mattress on their showroom floor. Both times I gravitated to this mattress. It is the most firm of the 3 Optimum model mattresses. I laid on all 4 of them as they were side-by-side. They got softer and more expensive as I went up the line. I've only had this mattress for a week, so my review is an early one. I had no intentions of getting a foam mattress when I went shopping. I was concerned about comments about them sleeping hot. This mattress does not sleep hot in any way shape or form. The salesmen explained to me that the initial Optimum mattresses didn't have enough cooling gel and they have added more and it has resolved that complaint. I concur. I haven't noticed any problem with sleeping hot. The biggest thing you will notice with a foam mattress is you won't feel any pressure points like a box spring. When I laid on any box spring, I would immediately notice a pressure point on my hip and my shoulder. I don't feel anything on the foam. I have slept just fine for the past week and no complaints of back pain or any pain in the AM. I am impressed so far. Will have to come back on in a few months or a year and comment on how well the mattress is wearing. I have also read comments about this mattress having a odor when delivered. The mattress and the box spring were both in plastic when the delivery people unpacked them and installed them in my bed frame. I didn't have any odor at all, so I'm not sure where that is coming from? I bought 2 of the Optimum pillows which I slept on before my mattress was delivered. They smelled a bit for a few days, but it gradually went away. I did not buy this mattress from Amazon, but decided I would comment on it here after I did buy it. These reviews of all kinds of mattresses are so frustrating. Who is commenting? The company that makes the mattress? The competing company? Disgruntled employees? I am just an ordinary consumer that needed to replace his 25 year old box spring mattress. I've owned 3 Sertas and a Beautyrest. This is my first Sealy. The salesman was telling me that several of these companies have bought out each other, so they are all about the same manufacturer now. I am pleased with my choice so far and recommend you go lay on this mattress if you prefer a firm one. This was the most firm of all the foam mattresses I laid on.
I can't believe how much money I spent on this bed! It is the worst purchase I have ever made in my life! I have never had such severe back and hip pain when I wake up in the morning. Do not waste your money on this or Sealy's adjustable (head up only) frame! You can feel the space in the frame when your head is raised through the mattress…terrible!!! I recently spent two weeks away from home sleeping on a cheap mattress and felt so great in comparison to being back home sleeping on my expensive junk!!!
I've had this mattress for 8 months and it has yet to 'break in'. When we went to mattress store, we laid on all of them and ended up with this model. It felt perfect. For some reason, the one we got is like a brick. Both my partner and I are on the lean side, but still.
I bought this mattress on march 15 and the first 4 nights I loved it no back pain and very good support but then I started noticing that although the memory foam always went back to its original form the inner layers of non memory foam on the where getting softer and I no longer had a firm mattress. Im a stomach sleep and this mattress turned onto a nightmare I hated how soft it was and when I was watching tv my bottom would sink in all the way. I no longer have mid back pain like my inner spring but now my neck and shoulders hurt from the rest of me sinking and putting stress on my shoulders. The box spring on this matress is horrible it does not provide any support and the whole motion transfer thing was as advertised for the first week after that i could feel my husband moving. Not as much as an inner spring but not was it was when i first got it well to top it of on the first week of april I called the store where I got it and told them it was sinking and sure enough a tech came and siad it has sunk 3/4 of an inch in less then a month so they gave me the option of getting another one or one for greater or lesser value. I decided to get the tempurpedic contour select it was $1300 more but my parents had bought one a week before I got my sealy and the tempurpedic is still as great as the first day so I didnt wanna risk it with getting anything else. Now im sleeping like a baby and glad I could change it.
reviewed on Dec 05, 2018 Purchased Sealy Posturepaedic from Harvey Norman, Warwick,QLD in March 2016. Within two years of use the mattress has sank in the middle, low enough to make uncomfortable even to just lie down rather sleep and cause body aches. Have rotated the mattress periodically as specified but just not durable even though the warranty is 10 years. The warranty terms and conditions doesnt justify for claims. 30 35mm sag is deemed to be normal in their terms. But given the width of the double mattress not much, that sag is substantial enough to cause issues to the body. They claim to use titanium springs for durability in their mattress. but having used for two years it has to be concluded that it is poorly engineered and the quality of their product is compromised for a rip off.
Put he’s a queen size Sealy from Macy’s in ChicAgo burbs in late 2017. Paid about $1,200 tax and delivery. Started to sag really badly in the middle after 5 or 6 months. I called Macy’s to complain since it’s under warrenty. They sent a technician out to review and look mattress over. The tech measured the depth of the sagg and it was well over 2 inches in the middle. I’m 5’8” and weigh 175. This is a sealy brand but I don’t have a model number. It was on the softer side with a pillow top. My back and hips were sore every morning. Macy’s made good on the warranty and I chose the firmer model as the replacement. Well, 6 months later I’m laying in a huge gully or canyon again. I’m beginning to wonder if these Macy bought models are more low end then high end. Time to call them back and replace number 2.
I will never buy another product from Sealy. I bought a Thermapedic Mattress made by Sealy from Rooms-To-Go. The adjustable base would not raise the mattress within two weeks of purchase. I was directed to Sealy through RTG customer service. The Sealy agent stated that the base needed resetting. She wanted me to go under the bed to get a box to reset the base. When I informed her that I was unable to go under the bed, she told that Sealy does not send repairmen to reset the box. She told me to call her back when I could find someone who could go under the bed. When I informed RTG of her response, a RTG repairman was sent He went under the bed and retrieved the box. He stated that the adjustable base was broken. Resetting the box would not have fixed the problem.
Horrible hard and very thin not even worth what I bought it for
I got the mattress I was highly disappointed. To begin with its a 3 inch mattress. Not happy at all. This was the worse mistake ever. I returned the bed and mattress. Had to take a $125.00 restocking fee and a $50.00 re delivery fee. Plus the only way that I can trade it in was if I bought a new bed so I will take the loss this whole thing leaves a very sour taste in my mouth and I will take the loss the picture above is very misleading. do not buy this product
The mattress is so uncomfortable!! Ughhh! Hate it will not keep
I ordered before the previous review but read said review before my order arrived. So I was not surprised when my order arrived and the mattress was thinner than I originally expected. It looks much thicker in the picture. The box spring is probably double the thickness. With saying that, it is still a good height if not on the ground. The mattress is quite firm but I still go right to sleep as soon as I lay down whereas that was not happening on my old mattress. I would reorder.
I ordered this mattress online. Cheap & cheerful... or so I thought. The mattress was delivered today, its smaller (in thickness) than the box springs. The image on this product is completely misleading. The mattress is probably 2-3 inches thick. Completely disappointing & extra frustrating.
Buying a mattress online is risky. However, if you are not physically able to get out and shop, you may have to do what you have to do. I bought this knowing I wanted a mattress with a plush top. I wanted it to be durable and strong enough to hold but when I laid down on it - it was soft for arthritic patients. I love this mattress. I look forward to going to bed and I don't wake up in pain from laying on a hard mattress.
The matteress is to soft. I should have ordered a firm
Great mattress equals many great nights of sleep! Plus the delivery service was great also.
liked how I got a good deal around presidents day.
I had thought I had ordered a firm mattress but a plush pillow top was delivered. I was gone at the time it was delivered at my house, the old mattress & box springs were gone and the new this set was on the bed. So, it couldn't be returned.
I ordered this bed set on line with out trying it out big mistake. I'm sending it back, its like sleeping on a deflating air mattress. I woke up soar it's just way to soft for me.
I saved a ton of money of my new Queen Sealy mattress and am now sleeping better than I ever did on one I spent double on!
We bought this bed on sale and were not disappointed! This bed is amazing. It is definitely plush and not a firm mattress. The delivery service was outstanding too. They called us often to update us on a time and they were in and out and made sure everything was perfect.
I sleep very good since I purchased this mattress !
I have a bad leg and need surgery from a injury 40 some years ago while in the military and this mattress is a GOD sent for my back as well.
Me and my boyfriend purchased a new bed and we're surprised that after 6 months the quality is horrible the bed is already dented as if the bed was years old. I am very disappointed with the quality of this bed. I will have to do my research more thoroughly next time before I purchase a new bed.
The mattress was as indicated, but I needed the firm pillow top so I returned that mattress and box spring and re-ordered the firm mattress only. It was for my guest room bed that has storage drawers, so when I received both pieces the bed was to high, you need to be 5'6' and up to be able to sit or get in the bed. (:
I love this bed. Very comfortable. I would recommend this Bed to friends and family.
My mattress arrived in the time frame that I was told it would come. It is a great mattress.
This was a perfect purchase. Arrived on time, white glove service, and the most comfortable bed I've ever slept in. Highly recommend!!
I would not recommend this set at all it is extremely too soft. It is so squishy that when I sit on the side of the bed to get out, I feel like I am trying to pick up my butt off the floor. It is not comfortable because there is no support.
I have a tender back and don't wish to sleep on a tender mattress. I found Sealy Essentials Holly Hills Firm Mattress paired with the special box springs saved my tossing and turning to into a great night's sleep. I feel refreshed when I wake up with no back pain or discomfort.
I purchased this mattress for a redecorated "kid's" room/home office. All of my grandchildren are teens now and the daybed no longer accommodated their growing bodies. I love the quality and value of this product. The mattress is firm, but comfortable, and is an extremely good value for the price.
