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.

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.

We were skeptical of a memory foam mattress but after some research and reading other reviews decided to give one a try. It is a fantastic mattress and we are sleeping so much better with no hump in the middle which our previous mattress had from early on. Would highly recommend!

Very nice. Takes getting used to, compared to an innerspring mattress. No bounce at all. My back hurt some after the first 2 nights, but once my body adjusted, no problems. It is a little more firm than my personal preference. I am a big guy and I was worried about being hot. So far, it is very comfortable.

I have been shopping for a mattress for a few weeks. Couldn’t match the quality with the price I wanted to pay at any of the furniture or mattress stores. This mattress is extremely good quality at an extremely good price. Very happy with this purchase.

I replaced a old spring mattress with this Memory foam one. I have been watching the development of the foam mattress for a while. I was always worried about the heat and the mattress being too soft. This mattress has multiple layers to keep it cool and is firm. I have found that I do not wake up in the night or toss and turn as much. It gives great support for your back while contouring to your body on your side. I would definitely recommend this mattress.

Seems like a quality product. A little stiffer than I'd like, but everybody else in my family says it's perfect. I guess that's better than too soft. There's no topper or other remedy for that problem. Took awhile to get here because of backorders. But it came in good condition. Try to get it on sale if you can wait. But a hundred dollars here or there is not a big deal for something you'll be sleeping on every night.

I bought thsi for our son's bed to replace a matress that was a hand me down (20yrs old) He says it it very good to sleep on and likes the firmness but softness that it gives him when sleeping. He says he sleeps in one spot now and doesn't toss and turn. I'm glad he really likes it

We bought this bed about a month ago, we didn't want to spend 1500 dollars again on a mattress set,since you can't flip most mattresses any more! The more exspensive need was definitely more comfortable , but for a third of the price, this one will work, for now ! Getting it shipped in a box was definitely awesome though!

Best sleep I have had in years. Have had it a month. After a week it hurt my husband hip (he is a larger guy and prefers a soft bed) so we got a 3" cooling memory gel topper and its been great. You wont be sorry getting this. If it's a tad too firm just buy an egg crate topper or gel topper
