Wow, this is by far the most incredible deal I’ve ever stumbled upon! I’m still in awe at the remarkable quality of this bed-in-a-box! Initially, I approached it with skepticism, as I usually fork out thousands for a premium mattress. However, this one surpasses every other mattress I've owned in comfort and support. It has completely transformed my expectations, and I can confidently say I will never splurge on an expensive bed again! I was so impressed that I ended up purchasing another one for my own room to replace my old mattress. I opted for the luxurious 14-inch cooling model first, and then I couldn’t resist getting the 12-inch version as well. Honestly, while the 12-inch mattress is fantastic, the 14-inch truly justifies the slightly higher price—it fits my sheets perfectly and offers a plush, cloud-like feel. Both mattresses, however, are of outstanding quality and exceeded my hopes. Ever since I made the switch a few months ago, I haven’t experienced any lower back pain, which is nothing short of a miracle! My husband is no longer waking up drenched in sweat either! If you’re on the fence about purchasing this mattress, don’t hesitate—it’s an absolute gem!

Can't beat it for the money, bought this planning on getting a mattress topper and ended up being comfy enough that we didn't need one.

At least in the full size mattress, which this is, it’s fine even though it was a boxed mattress. I don’t know if it’s true for the queen and the king size. Usually on the larger mattresses, they’ve got a roll them up and then fold them over and they have to manufacture them differently to be able to fit in a box like that. I was surprised for a little over $400, I was able to get this mattress for a guest room and not have to spend hardly anything for a comfortable mattress that someone could use without complaint. It’s a hybrid, enter spring type mattress with the foam layers above the springs. You can tell they’re very careful not to give us too much comfortable foam layers, but in this case there’s just enough foam to where you really don’t feel the springs. I can recommend this full-size mattress or a guest room or some use like that so you don’t have to spend a ton on a really expensive mattress. I don’t know that I’d recommend it for a couple on a larger bed. Generally better off going to the mattress store sitting on a few and paying a couple of thousand for a good mattress. I just bought a Sealy posturepedic hybrid elite 14” high point 2 which is a proprietary store brand from Sealy. I bought a medium it’s supportive, but you don’t go down too far. So it’s not gonna be too hot. It was after I checked out all the hybrids believe me that’s the right one. The firm is too firm. The plush is too soft. The medium is just right. If you wanna get a good mattress, you need to go to a mattress store somewhere especially in a king size. It’s hard to compress all those good springs in a box and also get a good foam layer in a box. There’s just not enough room to put good components and then compress it all, and have it fit in a box. I would suggest avoiding all box mattresses.

I bought this mattress for my 72 year old mother as an upgrade from her regular spring mattress. We were unsure on what she would like so we went the more affordable route compared to a Tempur-pedic. She has enjoyed the softness of the mattress yet firmness of the support. She has a lot of leg pain and has expressed less pain with the new bed. The 14 inch thickness is great and no box spring is needed to feel comfortable. The mattress is a little soft on the edges but she doesn't seem to mind so far. I would recommend this as a cheaper alternative for a decent bed.

This mattress is the best mattress we have brought in a long time and don’t plan on buying another one for a very long time. It’s firm but soft, I can’t feel my boyfriend when he wakes up for work so my sleep is not disturbed, and it is has enough space for both us of to stretch out and still not hit each other.
