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.

This mattress is very comfortable. We bought the same one a few years ago, and it is still as comfortable as the first day we used it. We needed another for a guest room, so decided to purchase the same brand/style, since we have been so pleased with the first one. It was shipped in a tall box that had the mattress rolled inside, so it was relatively easy to move to the room. The mattress expanded to its full size over the next day or so.

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

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 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.

This is the second Serta SleeptoGo we've bought. It is a very comfortable mattress, easy to get into the house with the box with the handles and wheels. BUT, it is not a true 12 Inch thick mattress, which is a little dissapointing.It measures at 11 inches. Would be getting 5 stars if measurements were accurate. Also noticed the cover is a little slack at the bottom corners on this second one, my first one is not slack like that. That leads me to believe they may have actually shortchanged the entire mattress, while leaving the cover the same size. Manufacturer would save a lot of money on a few inches of foam x thousands of mattresses. Still, a good value for the money and comparable to the Casper, which is twice as much money.

I bought this mattress for my guest room. It is firm, but it's a softer firm than a standard mattress. It is quite comfortable to sleep on. The mattress never expanded to 12 inches, but that has not impacted my review of this product. I would buy this mattress again!

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!

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.

Usually there is a break in period for a mattress. This mattress was very comfortable from the first night. The only problem was the delivery aspect. Even though free delivery was offered, due to mess ups with Fed Ex, I had to pick it up myself from the Fed Ex facility.
