Expert Review By Jed
The Sealy Posturepedic Cooper Mountain III Plush Euro Pillow Top is the softest model in the standard Posturepedic category. The King size is designed for couples who are side or back sleepers that want a very soft mattress. Stomach sleepers should be aware that too soft of a mattress can cause them to sink in and overextend the arch of the back, which can result in extreme discomfort after an entire night. This model received a very soft Comfort Scale rating of 8, offering cloud-like comfort.

The Cooper Mountain III Plush Euro Pillow Top uses the Sealy Embrace Coil System as its foundation. This system utilizes individually wrapped coils that react independently from their neighboring coils to effectively contour to the curves of the body. In addition, this design does an excellent job of reducing motion transfer and is also adjustable base friendly.

On top of the coil system you have high-quality comfort layers like SealyCushion Extra Soft Foam and SealyCushion Ultra Soft Foam, both of which go through a pre-compression process at Sealy to ensure consistent comfort and prevent uneven wear for a long comfort life. SealyCool Gel Memory Foam is used to reinforce the lower back area for proper, healthy spinal alignment despite the extreme softness of the other comfort materials. The SolidEdge HD System strengthens the perimeter of the mattress to prevent roll-off, which is nice for couples sharing the King size so they can get the most out of their respective halves.

All in all, the King size Cooper Mountain III Plush Euro Pillow Top is a luxurious choice for couples who want a soft mattress. It comes backed by a 10-year, non-prorated warranty, and a very affordable price tag for a King.

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.

Way too soft, poor shape, little support
March 21, 2017
This seems like it should be a 10 for soft, not an 8. If clouds are your thing, you may like it. It's soft which is nice at first, but with the level of softness comes poor center support, poor neck support (think your midsection where the weight is sinks in, your head sinks and slopes a bit, feet are higher)... if you should roll to the edge of the mattress or sit up there, the edge completely gives in. I'd think this would be hard on older folks especially.
Pros:
Ok material quality
Cons:
Way softer than we thought, poor support, body aches, seems warm, edges collapse with weight, the middle sinks!

Nice mattress for smaller folks
January 17, 2017
Delivery went well. Mattress in good shape on arrival. Comfortable for sleeping on your back. Significant hip pain when sleeping on your side. Probably because of my size (230).

Great mattress
January 6, 2017
I've had this for about a month and still love it! It's very comfortable yet still firm enough to be good for my back. I still have time in my 100 days but I don't plan on returning this. Please note that ANY mattress you buy will be more firm in the first 30 days, kind of like a shoe, you need to break it in. I'm happy with the purchase and had no problems with delivery or ordering! I went to many mattress stores to get a feel of what I wanted, told the online chat person and it's perfect.
Pros:
Comfort Price

Saved my back
January 3, 2017
I'd been sleeping on an ancient mattress that was gradually maiming me (only a slight exaggeration). I ordered this mattress on a day when I couldn't take it anymore, and it's been a life saver. I actually look forward to going to sleep now since I can sleep through the night and wake up without pain. My smartest purchase of the year.

Give it Time
December 2, 2016
When I first received my mattress I was ready to return it. But obviously returning a mattress is a lengthy process so I thought I should give it a fair trail, especially considering US-Mattress's generous 100 day return policy. The first week or so the mattress was more firm than I expected, but after a couple of weeks it broke in and is really soft! The reviews on this mattress were very accurate.

Very Happy - Great Company
October 15, 2016
This was my first time ordering a mattress online. After a lot of research, and reading reviews, I went ahead and placed my order. I am very happy and pleased with the purchase. The price was fantastic, and free shipping. I have not much stomach for the mattress stores. With different names for the same product from one store to the next. Worse then buying a car. The mattress arrived very well packaged and protected during shipping. I would buy from US Mattress again.
Pros:
Well packaged for shipping. Pillowtop is awesome. Very comfortable.
Cons:
None so far.

July 31, 2016
I really liked the website, it was easy to order, customer service and the delivery guy were very helpful and friendly and the mattress is comfortable and matches the description, except for the length- it is about 1.5 inches shorter than advertised. I haven't contacted the company, it's not a huge deal and maybe I'm not measuring it the way they do. That was the only con of this experience.
Pros:
Website Customer service Delivery Mattress Comfort and Quality
Cons:
