Expert Review By Jed
The Sealy Posturepedic Cooper Mountain III Plush is the top of the entry-level line of Posturepedic plush mattresses. It has a medium-soft Comfort Scale rating of 6, which works well for virtually all sleeping types. The Queen size of this model is great for your own master bedroom, but also for guest bedrooms because its middle-of-the-road comfort has a nearly universal appeal.

The Cooper Mountain III Plush achieves its medium-soft comfort by strategically stacking comfort layers on top of a flexible and supportive coil system. The comfort layers include high-quality polyfoams like SealyCushion Extra Soft Foam and SealyCushion Ultra Soft Foam. These layers envelop you in comfort, supporting all the curves of your body to reduce pressure points. At the same time, SealyCool Gel Memory Foam reinforces the center third of the mattress, bolstering support to the vital lower back area to ensure proper spinal alignment.

The Sealy Embrace Coil System consists of a series of individually wrapped coils that perform independently of neighboring coils in order to provide precise contouring, accurate support, and improved motion transfer reduction which is invaluable for couples. This coil system is also adjustable base friendly for those who have experienced the luxury of an adjustable frame. Sealy's SolidEdge HD System reinforces the edges of the mattress to prevent roll-off, which is another nice feature for couples so they can get the most out of their respective halves of the bed.

In conclusion, the Queen size Sealy Posturepedic Cooper Mountain III Plush is a great value for couples of all sleeping types. The balance of contouring and support is designed to keep every sleeper comfortable, which also makes this mattress an excellent guest bedroom solution. This model comes backed by a 10-year, non-prorated warranty for years of enjoyment.

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

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.
Pros:
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!
Pros:
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!
Pros:
Plush & Soft Supportive Handles to make moving easier Motion transfer controlled
Cons:
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...
Pros:
Comfort and support
Cons:
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.

We were really looking forward to our new mattress set and we were not disappointed. It is so comfortable, first nights sleep was wonderful. The fellows that delivered them were so nice and professional. Came in, set up and were gone in less than 10 minutes. Extremely happy with our purchase, the price and the personnel. Great job US-Mattress!

Less back pain
May 8, 2015
I'm really glad that I bought this mattress and I'm even gladier (hush, it's a word!) that I got it from US-Mattress.com. I had ordered one from another store that cost more and the delivery department gave me the run around! I love this mattress. I noticed a decrease in back pain after only a week.
Pros:
Comfy!!
