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.

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

This was a top rated mattress in a consumer reports study and it was one of the least expensive mattresses rated. Sam's club offerred it at the CR magazine price and so I bought it. It is a excellent mattress at way less the cost of most of the others rated.

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.

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!

I was a little afraid to order a mattress . But I know Sam's has always stood behind what they sell. It's perfect ! I have a bad back and this mattress is like the best I've ever slept on. it's wonderful and very happy I stuck my neck out and bought it. I'd do it again ! Plus it's a great price !

No doubt it's a quality mattress at a good price. Problem is we didn't anticipate how awful the out-gassing would be! It gave my wife a severe headache for 24 hours. We moved the mattress into a laundry room to then outgas for another 5 days which gave me a slight headache every time I was in that room for more than a minute. IF you are chemically or EMF sensitive either don't buy a memory foam type mattress (of any brand) or make sure you have clean garage or other place that doesn't "share the air" and can leave it to outgas for a minimum of 2 weeks.

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 wasn't sure what to expect, the reviews on firmness went both ways. So, I'm writing mine just to add to the mix :) Came a little bit later than expected, but it wasn't a surprise since I got it on the one day sale. Which I've noticed the price for that has popped up again on sale, so it isn't just the one day price. Box wasn't wrapped, so it wasn't a secret what was in it. Came perfectly fine, no dents or tears. The mattress itself was wrapped tightly in plastic. Pretty amazing really. It sat in my bedroom for a couple of days since I wanted to open and let it air out overnight and I still had my current mattress to be picked up by my son. Make sure you put the mattress on the foundation you plan to use before you start cutting. This is very important. Old mattress out. I have an antique Queen size bed frame that uses wooden slats as the foundation, plus I have my old box spring. We placed the Serta on the box spring and started to carefully (be very careful) cut the plastic. It is really amazing that this bed is only about 3 inches tall when still in the vacuumed package. Cut diagonally and do it fairly quickly. The bed starts sucking in air and expands to the full Queen size in literally 2 minutes, maybe less. Aaand, you're done. It does say 12" and mine has fully expanded to 11 1 /2" . Close enough for me. First thing I noticed is after coming from a pillow top was how flat it is. Flat, flat. No lumps or comfy spots, just flat. Don't try to do the cute little jump and land on it, it's flat and firm and not a lot of fun. First few nights I was unsure how I felt. It was firm, but after about 15 minutes I stopped noticing it was firm. Weird. It is because of the memory foam, weight and mixed with body heat, it conforms to your body. I've had it now for about a month. I can definitely tell where I sleep and where I do not. The softer side is where I sleep each night. As time goes on, the memory foam softens. It isn't squishy soft or like it is breaking down, but it does that conforming thing much quicker. If I want to lay on the firmer side I crawl over and can tell the difference immediately. I still struggle with pillows. I can't find quite the right match to get me through the night. I hope that you won't have that problem. This is an ongoing struggle. BUT the biggest thing (If you're still reading, you are smart) is that my husband has commented that I have NOT SNORED ONCE since I got this Serta mattress. Why? I don't know, I can't find the right pillow, so I can only say it is the memory foam base. I had a pillow top that cost over $3200 and I snored; but this mattress has made me so comfortable that my neck is not curled in such a way, and I've stopped. A month in...nope, no snoring yet (and I've even got a head cold this week). Another thing I noticed immediately was I often woke with my shoulders in pain like I've shrugged them all night. Seriously, that was gone on the first morning and hasn't come back. Yes it is firm, but it gives after a few minutes to be comfy, and just keeps getting better.

I purchased this mattress solely because of the rating it received from consumer reports (and the reasonable price). It is advertised as a 12” mattress, but mine is barely 10” after two weeks. I’m a side sleeper and it was way too firm for me, so I purchased a 3” memory foam topper. So far, after only two nights, It is much better, but I will reserve final evaluation for a month or so.
