The fact that you can get a really comfortable mattress shipped to your house with a great price is so cool! I read a lot of mattress reviews, this one was the best reviews. Got it home, super heavy of course. Open with plenty of space for it to fold open, it’s kind of bent like a taco lol When you open it, it springs open it like a angry butterfly 😂 almost got me in the face lol my fault of course! Glad we didn’t do a how to video! We let it rest for 24 hours so it can breathe and the foam can expand, seemed like it was done by mid day but we let it sit the full 24 hours. First night of sleep without my husbands shoulder hurting, he’s a side sleeper, I’m also a side sleeper so my lower back is always hurting. Woke up with no hip or lower back pain! It’s very comfortable, not too hard, not too soft. No smell to it. The grand kids jumped on it to test out the springs, it held up just fine lol I like that I don’t need a box spring for it and it’s high enough without being too skinny of a mattress.

In all honesty, I had really low expectations and was a tad bit scared I wasn’t going to be happy with this mattress at all. After laying on it for a couple weeks, I can happily say this mattress is great! It’s comfortable and soft and helps with my back pain. Even with me moving around a lot in my sleep, it no longer really bothers my partner. Easy set-up by myself for someone with minor disability.

This mattress is 100% more comfortable than the $1200 mattress I bought years ago. I slept on this mattress the day I got it since I had no choice and it still was comfortable, and it still inflated to full size over the next few days. It didn't smell weird and I genuinely love laying on it. It feels like there is support with a little bit of cushion for that comforting feeling. I can't speak on long term since I've only been sleeping on it for a week but I would jump at the opportunity to buy this a year from now if it were to lose it's quality. Ultimately, it'd be cheaper than buying a $1200 mattress that lasted 4 years. In terms of the mattress lottery on Amazon, I am so happy I bought this one.

Mattress came in box, rolled up. Very heavy box to carry upstairs. Once unrolled, it came up quickly. We let it set up without sleeping on it for a week. The first photo is what it looks like now. There are places I wish it would have rolled out better, however, it was shipped in a box and for the price it seems great. I am impressed by the firmness yet softness. The fitness creates a support that creates comfort. I ordered a queen size 10 inch bed for my toddler and so far do not have many complaints. No odor was noticed when unpackaged.

Size: Twin XL
I will preface this review by first stating that I did not purchase this mattress for extended daily use, but rather for occasional use for our cabin. I purchased two Twin XL to make into a king because the mattresses had to be easy to lift up a narrow staircase. These mattresses exceeded my expectations, and we slept well on them. I was nervous about the first night since the mattress information said it would take 3 days to fully expand, but they were comfortable from night one. Unlike traditional memory foam mattresses, we could sense small movements throughout the night, but it was minimal compared to the old traditional mattresses we replaced. For our purposes, these exceeded our expectations, and the price was perfect for use cases.

This is a very well made enter spring hybrid mattress, the only other thing I can say at this point, is how well it holds up, so you'll have to check back in a year or so. A side note, I have been sleeping on various memory foam type mattresses for the last 20 years, and I can say with all honesty, I never want to go back to any kind of memory foam mattress again, the first night I had this, I really slept great, I slept the way I used to sleep when I was much younger, on innerspring mattresses, skip all the high tech nonsense, I believe Inter spring hybrids are the way to go.

I’m pretty happy with the purchase I need to wait more to see how good it is. I’ve slept for a week and it has been really comfortable.
