Expert Review by Jed
If you're a side sleeper who needs great pressure relief or simply someone who enjoys a soft yet supportive level of comfort, the King size Sealy Posturepedic Response Performance Cooper Mountain IV Plush Pillow Top Mattress is a great way to go. The last generation was one of the most popular models not only from Sealy but on our site in general, and the newly improved version features several upgrades across the board. Scoring a rating of 7 on our Comfort Scale, this mattress has a soft initial feel and offers firm underlying support.

Significant improvements to the Cooper Mountain include the Comfort Loft Cover with MoistureProtect, a quilt that is specially designed to wick away moisture to help you sleep comfortably cool. Comfort is primarily provided through a variety of high quality polyurethane foams, all of which are CertiPUR-US Certified. Uniquely designed to promote airflow, a layer of Sealy Air Foam provides some initial body contouring. A layer of SealyCushion Extra Soft Foam aids in soothing pressure points to decrease tossing and turning as well as promote better blood circulation. The SealyCool Gel Memory Foam layer located in the center third provides additional lower back support, and it even promotes prolonged durability. Another layer of SealyCushion Extra Soft Foam guarantees deep down pressure relief, and it is appropriately designed to help side sleepers get the contouring necessary to prevent waking up with achy limbs. The Sealy Response Pro Encased Coil System provides support and consists of over 200 more coils than last year's version. This coil system is among the most forgiving on the market, and it contours well to your body's unique curves while simultaneously delivering deep down support. This system is especially beneficial for couples and those who expect a pet to jump into bed because when movement occurs on one side very little motion is felt on the other. It's also fully with an adjustable base compatible. Certainly one of the best edge systems available, the DuraFlex Edge also represents an improvement in edge support technology. It allows you to rest comfortably anywhere on the mattress without noticing much difference in comfort or support.

To summarize, if you like a soft comfort level this is one of the top choices available on our site. The attention to detail Sealy has given to this mattress is incredible, and it leaves nothing to be desired at this price point. This mattress comes complete with a 10-year warranty to ensure your satisfaction.

Firm mattress
If you’re a back or stomach sleeper, this is a good mattress. The mattress is too firm to sleep on your side. I would recommend to some but not all.

Great mattress
Great mattress, very comfortable. I was a little concerned it was going to be too soft being a "plush pillow top" but not at all. Great online service and no-hassle, fast delivery also.

Great Quality Mattress
My husband and I both love this mattress (we bought the queen size). It’s on the softer side but not too soft and still has good support. I sleep on my side and he sleeps on his back, and it’s very comfortable for both of us. Delivery was also very easy to schedule.

decent bed not as soft as advertised
I am 6'4" and 230 and this bed is pretty nice. I ordered one that was a 7 on the comfort scale and I would say it is closer to a 5. Outside that I would recommend it although the sale price I purchased this at seems to be nearly identical to the every day price.

Love this mattress!
We replaced an ancient Tempurpedic with a King Cooper Mountain pillow top mattress and it has wonderful. Since we had been sleeping on such a hard surface, it did take about a week to get used to a softer mattress but now I absolutely love it. Our old mattress had given me a pinched nerve in my shoulder, and it is finally starting to feel better with this new mattress. I will say if you're used to a firmer mattress and that is what you absolutely want, I would forego the pillow top. Otherwise, buy this and enjoy it!
