Mainstays 8 in Memory Foam Mattress, Twin

So I waited a copy of days to post my opinion! Me and hubby were having trouble getting rest ..so I decided to buy this item …let me tell you it is very comfortable. It expanded amazingly well maybe even bigger.. I follow all instructions—- no smell ..All comfortable I got a queen size price was good. Thank you

I had purchased this for a daybed for adult daughter to visit but when I say I decided to spend a couple of night on it to see how the bed held up when I say this was the most comfortable nights i spent in a long time, I have nerve damage in both hips and normally I'm tossing and turn but I woke up feeling energized and not as much pain it's still there but not as bad. The bed cup my body like a glove. This is my honest opinion now I'm looking to purchase for my queen size bed. Also I purchased the daybed here too

I tried this mattress because it had pretty good reviews and was fairly cheap but I was skeptical it would hurt my back because of the price and it came in a box vacuum sealed so it was lightweight bringing it up the stairs and it inflated so fast and it is SOOOO COMFORTABLE. The only reason I'm writing a review is because every morning I wake up and think to myself that this mattress is so good it deserves a good review.

I got the mattresses 2 days later. I unwrapped it sat it on my bed to expand. Didn't notice any chemical smell coming from the mattress itself. I completely removed the plastic packaging. After 30 minutes of expanding it's close to 8 inches, suggested expansion time on the manual says up to 48 hours to fully expand. Will update on firmness but so far the quality feels fair for the price.

We bought two of these in twin size for our daughters' bedrooms and were very impressed. They were just as high quality as any other online bed in a box purchase we'd made previously. They were well packaged and quite comfortable. For the price, they can't be beat.

if you dont know about these type of mateesses, beware, it is 6". I purchased this mattress as a replacement on a bunk bed set. when it arrived, and was unpackaed to decompress, I was actually shocked at how thin this is That is totally on me. I know, because I actually took out a measuring tape and measured it, yep, it's 6 in. maybe I'm old, (any maybe a little out of touch) but 6" aint what it used to be. needs support of some kind, or it will just sag between the gaps that being said, it is exactly as described and serves its purpose. great for a kids bed.

This mattress is horrible. It never rose past 6 inches and is so soft and awful. We waited and waited for it to improve and it only got worse. Customer service is absolutely awful and didn't help at all nor did they give me the correct places to file a complaint even though I had receipts and pictures . There is no way a 5 star review of this product is real . I would give this 0 stars if I could

There is another review from a guy that submitted a photo measuring the mattress and I completely agree with him. This is not 8 inch, it is 6 inch. This is not medium firm, it is soft. in 2024, I bought this product off the shelf from a store in Gulfport, MS for my dad's spare room. It was an amazing product. So I bought it for myself, in 2026, this time online. Either the manufacturer has significantly changed the product and is trying to pull a fast one or I was delivered the wrong thing. It's a glorified mattress topper

I sure wish I could get my money back on this. I've only had it maybe a couple months. the mattress sinks like you were 600lbs I literally have to get out of a hole to get out of the bed so now I have to find another mattress .. extremely disappointed

I can not believe this mattress is advertised as 8in We actually unpacked it and let it sit over 30 hours . 2inches exactly on ruler, extremely disappointed as most mainstay items are somewhat good. This was not one of them. Very frustrating as we now need to see how to return.
