We have had this mattress (12" Serta Sleep-to-go) for about 2 weeks. We bought it to replace a very old sagging pillow top spring mattress in our master bedroom. We were not a fan of the pillow top and have liked firmer beds in the past, so the negative reviews did not scare us. I should note that we have a sleep number in our other bedroom and are happy with it, but it's not great for non-sleeping activities, so we were hoping for an alternative. Shipping wise, the bed came on a Monday instead of the previous Friday that was estimated via email, but that didn't bother us. The box it came in was missing a wheel and part of the box was torn, but again that didn't bother us either. It was easy to unroll and unfold and it fluffed up to almost 12" almost immediately after unrolling it (12" on one side, 11 3/4" on the other an hour in). It had a not pleasant off-gassing smell, so we slept elsewhere the first night, turned on the exhaust fan in the connecting bathroom, and tried it the following night. My experience and my husband's experience on the bed were completely different. I am about 36 years old, 5' 8" tall, and 120 lbs and have slept well on any bed my whole life, cheap hotels included. Every night I slept on this bed I had extreme problems falling asleep (took more than 2 hours each night), woke up pretty close to every hour, and woke up sore through my shoulders, neck, and back in the mornings. I stuck it out for more than 10 days trying different pillows, positions (I sleep on my side, back, and occasionally my stomach), and switching sides of the bed with my husband. There was only very minimal improvement if any and I was still waking up frequently through the night and having numbness and soreness in my elbows and knees, which I've never experienced before. I stopped trying when I got a debilitating headache that lasted 8 hours and seemed to stem from the neck/shoulder/back pain and tightness (my first non-migraine headache in over 20 years). Needless to say, we will be returning the bed. My husband is also 36 years old, just over 6' tall, and weighs about 230 lbs. He generally sleeps on his side, and sometimes his stomach or back. He literally has had the best two weeks of sleep in his entire life on this bed. For the 17 years I have known him, he has always had problems sleeping - waking up in the middle of the night, getting up at 5:00 am because he can't get back to sleep, and basically living life in a state of semi-exhaustion. In contrast, on this bed, he has slept like a baby, almost overslept for work at 7:00 am, and says he feels rested and wonderful in the mornings. If we could cut the bed in half, we would. So if you are considering the bed...flip a coin?

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.

We are so glad we bought this mattress!! After looking at several different mattresses we decided on the Serta Sleep To Go and are very happy with our decision. It took a couple of nights to get use to the mattress but we've had it about a month now and wouldn't give it up. We both woke up with backaches every morning with our old mattress and now we wake up feeling great!!! Love this mattress;)

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

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 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.

All the reviews were great. As I was looking for a firm mattress. One person said they took it back to Sam’s because it was like sleeping on a floor. That’s exactly what I needed to hear. Sam’s delivered it, it better then I thought it would be. If you like it firm buy it.

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!

I bought this for my spare bedroom but when I saw that it is wider and longer than the gel foam mattress I have on my own bed I swapped them. It quickly inflated to a full 12 inches and is so far very comfortable. I would say it is medium firm which I like. Will have to wait and see about it's longevity.

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.
