It's good so far. We like the firmness, just as what was expected. The delivery was super fast well.

Why did you pick this product vs others?: The mattress is quite comfortable and supports me well. But that's not what I'm here to talk about. I actually originally purchased the 14-inch on accident, not realizing it wouldn't fit my living space. I contacted them asking if I could exchange it, and they provided me a half refund, helped me get a full refund on my warranty, and let me keep the original mattress. They went above and beyond to help me, and so I can confidently say that that their "satisfaction guarantee" has weight behind it.

I have never purchased a mattress outside of a store that I could test it in, so this was a first and i wasn't disappointed, turned out to be a great mattress.

I got this mattress for my guest room for when my nephew comes to visit. I’m really impressed with it! The hybrid foam and coil design keeps the support evenly distributed. There’s no saggy or lumpy bits, just consistent comfort. The set-up couldn’t have been easier, either: unbox and let it settle into shape before using. I didn’t notice any odd odors that can sometimes occur with foam mattresses. He’s a pretty big boy so I was concerned a twin mattress might not be big enough, but since he’s not tossing & turning, it works out just fine. He said it’s a more comfortable mattress than what he has at home, so it’s auntie for the win! Budget friendly, easy setup and comfort make this mattress a winner!

This is a really nice mattress. It looks great and it feels good. I got this to go on the guest bed. This is a really nice mattress. It looks great and it feels good. I got this to go on the guest bed. It’s not too soft and seems to be supportive. It doesn’t hurt my back. I like the thinner mattress because I eventually want to get a trundle to go under the daybed and I’m hoping this will fit it when I get a trundle.

I have a daybed which permits a large mattress on top, but for the trundle below, you need a lower profile mattress. This mattress fit the bill, and it was perfect for this application. Despite being only nine inches thick, it is still comfortable and offers great support. It seems to be well put together, as I did not notice any errors in the stitching around the perimeter. The mattress is firm enough to feel substantial, and doesn't leave you feeling like you're going to sink right through it like some other foam-only mattresses I've used in the past. It was easy enough to unpack and after about a day of sitting out, it was fully fluffed and ready to use. I've had several guests use it and after I've asked them how it slept, they only had good things to say. So if you're in a situation where you need a low-profile mattress, this is an excellent and cost-effective option.

I got this twin mattress for our guest room and it’s been great so far. The 10 inch hybrid design feels supportive yet comfortable, and the cooling gel helps keep it from getting too warm. Guests have mentioned they slept really well on it, and I agree it feels balanced with just the right firmness. I also like that it’s fiberglass free and has a long trial period for peace of mind. For the price, it’s a solid choice and I have no complaints at all.

This mattress has been an excellent upgrade for our guest day bed. It came well packaged and it fluffed up very quickly. I got it in a twin - 10" size and it was a great fit. I like how thick it is as now there is no gap against the daybed frame. It was easy to set up and twin sheets fit - no problem. I've slept on it and It offers great lumbar and shoulder support for nice comfort throughout the night. The breathable design keeps you cool. Overall, it provides the perfect balance of softness and support for both side and back sleepers. Highly recommend!
