One of the top all-around mattresses for couples in the Sealy collection, the Queen size Sealy Posturepedic Response Performance Cooper Mountain IV Plush Mattress features upgrades across the board to the already great generation III model. Scoring a 6 on our Comfort Scale, this model has a medium level of softness that is designed to offer an excellent combination of comfort and support.

Notable components and improvements start right in the quilt with the Comfort Loft Cover with MoistureProtect. This performance quilt is brilliantly engineered to wick away moisture for a comfortably cool night of rest. A layer of Sealy Cushion Air Foam offers some initial body contouring, and it has a convoluted design that encourages increased airflow throughout the mattress. Back support is reinforced with the help of expertly designed Posturepedic Technology, more specifically the SealyCool Gel Memory Foam that is incorporated into the center third. This foam not only ensures improved support, but also better durability. A layer of Sealy Cushion Extra Soft Foam provides deep down pressure relief to help prevent tossing and turning. Another benefit is that all the comfort materials used in this mattress are CertiPUR-US certified. Essential back support is provided with the help of the new and improved Sealy Response Pro Encased Coil System, an individually wrapped system that has a coil density of over 200 more coils than the previous generation. This new system delivers close body contouring, provides deep down support, and helps isolate motion transfer. This way, when movement takes place the other side remains unaffected. The DuraFlex Edge, which is one of the best edge systems on the market today, keeps comfort and support consistent across the surface, even at the edges, helping you make the most of a Queen size. The mattress is conveniently compatible with an adjustable base.

To conclude, if you want a great middle-of-the-road mattress in terms of both price and comfort, the Queen size Sealy Posturepedic Response Performance Cooper Mountain IV Plush Mattress is one of the best choices out there.

100 night comfort guarantee

Our Mattress Guarantee Is Simple:

We want you to make your purchase with confidence. And we know that even after making a careful selection, sometimes people need a different level of comfort. If you wish to exchange your mattress, we will make an exchange for you for up to 100 days after delivery. (A difference in lower priced models is non-refundable. An increase in price requires payment for the price difference. Exchange covers same size, limit 1 exchange per customer.) All you have to pay is a $139 processing fee. We will cover all other expenses. Find out more about our guarantees and policies here.

All we ask is that you spend at least a few weeks getting used to your new mattress first, before we process an exchange. Sleeping on a new (or any different) mattress takes a few weeks to get used to, and with that familiarity you can know for sure you're making the right decision.

QUESTION: Is this cooling gel Does this bed sleep hot? by Brian L 5/8/2015
ANSWER: This bed doesn't sleep hot. by Nannette B 5/10/2015
ANSWER: It is not cooling gel. The gel layer is inside the core of the mattress to provide greater support and durability. I personally do not find that it sleeps hot; that's more of an issue with pillow tops and certain kinds of foam. by Collier G 5/9/2015
ANSWER: To your first question, I don't know if it's cooling gel. To your second, the mattress does not sleep hot. No temperature issues for me at all. by Becky K 5/8/2015
ANSWER: The bed does not sleep hot. by Ranell J 5/8/2015
ANSWER: Hi Brian. I purchased this mattress because my husband likes to be COLD when he sleeps keeps windows open in winter even the mattress works wonderfully - and stays cool - hope this helps - its extremely comfy as well - by Margaret B 5/8/2015
ANSWER: I don't know if it's supposed to be "cooling" gel, but to me the bed does not sleep hot. I'm the type of person that needs the AC turned up when I sleep. I'm very glad I bought it! Less back pain too! by Tonderleir T 5/8/2015
ANSWER: It depends on individual I guess. It does sleep hot for me but not for my wife. I would suggest buying a cooling mat if you think it's hot available in costco around 120 bucks here in CA. Also give it some time; your body may adjust to it and you wont feel the need for cooling mat after a couple of weeks. by yogesh d 5/8/2015
ANSWER: This bed doesn't seem to sleep hot, or not that I have noticed in the past 8 months by Rachel P 5/8/2015
ANSWER: I've had this mattress for about a year and have never felt like it slept too hot. Super breathable by Lauren H 5/8/2015
QUESTION: Is it necessary to buy a box spring with the mattress Will it avoid warranty without box spring It says the matching box spring provides better support, but what's the difference it really makes vs using existing box spring? by ppwen w 6/7/2014
STAFF ANSWER: Here is a video we created about using your own box spring with a new mattress: http://youtu.be/rjiZ98FB1PY by Jamie B 6/9/2014
QUESTION: I am a stomach sleeper that suffers from back pain and discomfort in my legs. I currently have a mattress on the firm side. I need a soft mattress that has support and can relieve my aches and pains. Would you suggest this mattress or should I go for the sister pillowtop bed with a 6 comfort rating? by Halimah A 2/17/2014
STAFF ANSWER: This mattress is a good choice. It gets its softness from two layers of SuperSoft Active Flex foam, which also helps relieve painful pressure points. You will get a soft, yet supportive level of comfort. by Jamie B 2/17/2014

Great Mattress for a Great Price

Super Comfortable, Excellent Support
April 16, 2017
This mattress is so comfortable and helps relieve pressure while still delivering a nice amount of softness. My last mattress was a 7 and so I was worried a 6 would be too firm. It's not - there are plenty of cushiony layers. I'm a side sleeper and my husband sleeps on his back and we are both in love. The handles are a nice touch to help with rotating. This is an excellent mattress and the price is amazing. I've seen mattresses at local stores with the same features at double the price.

Good for Side and Back
January 4, 2017
I sleep on my side or back and this mattress has just the right support for both. I do have a cover from our last bed that adds a little more cushion, but I do not really think it is necessary. I bought the same mattress for the guest room and it will be delivered soon.
Firmness as advertised (5 to 6) Moving on mattress does not affect the other half of the bed

Great Value
December 13, 2016
I have no intention of doing an exchange of this mattress. I got this mattress to replace my older Sleep Number bed. This Sealy is much more comfortable than that over rated Sleep number. Its very comfortable and I didn't need to adjust to the new one. It is a little firmer than you would think, don't let the rating of plush and not firm fool you.

Very comfortable! Love it!
August 10, 2016
This extremely comfortable mattress fully fits on top of my twin box frames. (The box frame was made into two pieces so we could more easily move it into the lower level of my house which has a tight corner.) I like how this company makes each mattress to order rather than just having it sit in the warehouse for a quick ship out. It's worth the wait!!!! Nice delivery men, too! Very responsible, careful, courteous!
comfort style made to order--so fresh, not flattened by sitting in a warehouse

Plush soft mattress as well as supportive
July 29, 2016
This is a plush soft mattress with an excellent underlying support. Great quality mattress and at a great price. Because of prior rib fractures and hip injury, I needed a soft mattress especially at the pressure points. In addition, it has a reinforced center that is more supportive for the mid third section such as hips and back. I am a very light sleeper and this mattress does not transfer motion as much, which helps. Best mattress!
Plush & Soft Supportive Handles to make moving easier Motion transfer controlled
Very heavy so flipping it over might be difficult for one person

So far so good

Versatile and Comfortable Mattress at a Great Price!
January 20, 2016
Purchased from US-Mattress and was delivered in about a week, have used it for a week and here is what I've found. Initially my wife and I felt it was a little stiff, however, I did buy a 3 inch Gel Cover from Overstock. The Gel made it hard to move around or get off the bed, but we found that since this mattress is a bit flexible, putting the 3" Gel under the mattress gave the mattress a Conforming-Feel, and still the support I need for my back. Been sleeping on it a week and no bad night's sleep yet, in fact, it's far more comfortable than my 100% memory foam mattress was and very similar feel to the Tempurpedic which is 4X as expensive. The Gel came with a full mattress cover which measures the full sides since this is now 17" thick total. Any higher and we'd have to jump up to get into bed. I also bought the 5" Box Springs but could not use them, sending them back I was quoted $250 processing fee, so be careful- if you won't need them, don't order them, I'll have to sell these on my own now. Other than that, the process went smoothly and we're very satisfied, the sides-support on the Cooper Mtn III is very nice, this feels like a high-end mattress in an expensive hotel, which is what I was looking for, comfort all the way...
Comfort and support
Haven't experienced any negatives with the mattress at all. I do suggest, as mentioned- to add the 3" Gell under the mattress, this mattress is flexible, and so if it seems stiff for side-sleepers, this Gell (topper) underneath has cured that.

Good Mattress
June 19, 2015
1st - the Rep that guided me through the purchase (Joshua D.) was most helpful and patient. The delivery was right on point. They removed the old and replaced it with the new. I'm still trying to get use to the mattress. I think it is a little to soft so I plan to get a pillow topper which I think will solve the problem. Even if you were to purchase a mattress in the high end department store after sampling it, the real test is after you have slept on it for a while.
