Have purchased memory foam mattresses in the past with satisfaction; however, they took at least eight hours or more to expand and there was a smell initially. With this mattress it expanded within five minutes tops and was ready to go. Sleeps really comfortably. My husband and I are both very pleased with this purchase and the price was just fantastic. We are both 60+ Years old if that helps you make any decisions

When I rolled this thing out on the bed and cut one end of the bag open, it started expanding so quickly I had trouble cutting the bag off fast enough to keep up with it. In less than two minutes, it was at full thickness. It didn't have any of that new mattress stink, either. I have joint damage to my right hip and shoulder which would bother me if I rolled over onto that side, but after sleeping on this mattress for about three weeks, I haven't noticed any trouble lying on my right. Much more comfortable.

I owned the exact same mattress for 6 years and it was time to replace. This was advertised as a FIRM and came in a generic box with no markings. there were no "details", warranty, or instructions included to verify the model and firmness, which is odd for a Serta brand mattress and concerning for me. That said, the mattress quickly took on the shape and depth and had zero smell. It just doesn't feel as firm as the previous one I purchased from Sam's 6 years ago.

VERY SATISFIED CUSTOMERS HERE!!! We recently bought an RV and the mattress that came with it was hard as a rock, and so uncomfortable. After researching mattresses we decided on this one, and we couldn't be happier. My wife used to wake me up with all the tossing and turning all night like she's in a kickboxing match, but now I don't feel a thing. If I could give it 10 stars I would.

I purchased this mattress because a family member also purchased it and loved it. I have colorectal cancer and sleeping became difficult with the radiation and chemotherapy protocols used to treat my cancer. This mattress has been amazing in the comfort, support and coolness. I've seen more expensive mattress, but not better. This mattress has been much more than advertised. I'm very glad I purchased it.

We bought the king size mattress to replace our 12 year old very expensive (but comfortable as well), Tempurpedic. Construction of mattresses have improved so much that you no longer have to drop thousands to get a firm good nights sleep. My husband set this up the evening we received it. Out of the box and on the bed. We were asleep in no time. We have been sleeping on it for a month and it is firm. DH is close to 300 lbs and 6' tall. Neither of us sink into the bed. It is incredibly supportive and we are sorry we didn't replace our old worn out mattress sooner. We bought this be on sale for $399 during the Sam's club event. Because of the deal and the reviews, we also bought a Queen size to replace on of our guest bedroom's mattress. This sleeps just as comfortably. We have tried both. TWO fine quality superb mattress for under $800?! Unheard of!! Don't think twice about this mattress. You will not regret it!

My husband and I were shopping for a new bed. After several stops and finding prices to be so high at other stores, we stopped in at Sam's and on an impulse went to check out their beds. My husband immediately loved the supported feel of this bed. I was used to our Sealy Posturepedic Pillow Top that we'd had for 12 years. The price of this bed was too good to pass up. I figured at worst, it would be a guest bed! Well fast forward a month and we've both had the best sleep we've had in years. The support on this bed is awesome. We are both in our mid 40's and we've started to have small aches and pains - NOT with this bed! It is not too firm and not too soft. Our Sealy mattress cost us well over 1200.00 12 years ago! Set up was a breeze. We opened it at 6:00 am and slept on it that night at 10:30pm and it was fully expanded. No smell, no issues!

We are 21 days into sleeping on this mattress. Our last mattress needed to be replaced. This memory foam luxury mattress allows you to get out of bed and not have a back ache. My husband feels that is is too firm but he is getting use to it. We are very satisfied with this purchase!

Before I purchased this mattress, I did an extensive online search comparing products and their reviews from Wayfair, Macy's, Ashley, etc and made my decision based on other reviews. So I most say, I am so happy I went with this mattress because my girls and I love it. They have a Queen size and I bought the exact mattress in a King size a month ago. I have never slept better as I am a side sleeper, who suffers from back pains. Amazing comfort at such an affordable price!

I have been sleeping on this mattress for about 2 weeks now, & it is so very comfortable. I notice from the covers in the morning that I do little tossing & turning anymore, as I did with my former mattress. Researched it with reviews & with the excellent rating given it by Consumer Report. Felt comfortable with making the $500 investment, & now with two weeks' sleeping on it, feel that I made a very wise choice for my replacement mattress. An adventure to watch it fill up quickly once the vacuum-sealed plastic is penetrated!
