I like a firm mattress but also comfortable. This one has been good thus far. I have some issues with my shoulder and hips. My arm has a tendency to go numb during sleep. Since I have had this mattress I have noticed that I do not have to prop myself up to get my shoulder off mattress. I am not sure if it is a back related or shoulder related issue but I haven't had the problems since I have been sleeping on this mattress. I would say "thumbs up!"

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!

We were looking for a mattress and did a lot of research and used CR. This was one of the top 25 in CR. Ordered online (queen). Mattress was shipped out same day. It arrived two days later. Was in a large box that weighed 70+ lbs. I noticed the box had a sticker on it that stated "serta e-commerce queen"? and no packing list on box or inside.....so before I decided to remove from shrink wrap I called the 1-800# for Sams/Serta. No one really new if this was the mattress I ordered so Sam's re-ordered another one and had this one picked up from my doorstep next day. All went well with second order. 2nd mattress arrived in a couple of days but this one also had queen e-commerce sticker on it along with no packing slip. I decided to open this one up and see what happened. It "inflated quickly and reached 12 inches within an hour. No chemical smell either. We woke up next morning without lower back pain. Been great ever since. We don't wake up hot either but we also keep our bedroom at 65-67 degrees! Would highly recommend this mattress for those with lower back issues. The mattress is not rock hard but not soft either. If you are looking for a plush soft mattress this is not a good choice. You can't go wrong either with Sam's customer service. They were awesome! Only negative/suggestion is Sams/Serta get the "e-commerce queen" thing figured out or make sure there is a packing slip attached to box or inside....... so they can eliminate unnecessary shipping/return costs to a minimum.

Probably the best mattress I've ever slept on. I have been wanting to try a modern memory foam mattress for awhile. It is the exact feel I was hoping it would be; firm but with a slight softness. A very nice mattress for the money. Highly recommend.

I bought this three weeks ago, delivered to my door. I took it from the box removed the compressed packaging. It fluffed right away ready to sleep on in 2 hours . I got in bed and laid down, and was saying to my self , ok this fees cool, very nice and the next thing i know its morning...too soon, its great

Replaced a older sams club memory foam matress that was 10 years old. This one is firmer. So far still a residual rubber plastic smell from matteess. I think the older one aired out in a couple of weeks, almost at a month with this one and i still notice the smell. I would rate it higher, but the chemical smell is annoying.

Bought this for our son's room/guest room. The bed had an older mattress and he has lived away at college since 2014. After graduating college in May he was home for the summer and realized how bad the old mattress was. We bought this and put on the bed for his Christmas visit. He loved it.

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

18 years ago we bought a similar mattress from Sam's Club and were extremely satisfied with. it. This one we have not liked as well. 1. It took longer to fluff out, so we had several nights of sleeping on "wierdness" while we waited on this to happen. However, it did fluff out as predicted. 2. It is extremely firm. Much more so than our last mattress. I liked it, but it hurt my wife's back. Se solved this by buying a mattress topper. I feel that it is a good quality mattress if you like firmness. Now that we have the topper, it is great.

I’ve had this for two weeks and I wish I ordered it sooner, I’m finally sleeping and feeling rested for the first time in 3 years. I bought a more expensive mattress 3 years ago and it was an expensive mistake. I would recommend this mattress to everyone. And it was delivered to my home.
