I’m extremely happy with this mattress. It expanded quickly after opening and reached its full size within a day. The hybrid design gives the perfect balance between support and comfort. It’s firm enough to support my back but still soft on top. I’ve been sleeping much better since I started using it. There’s no noise or sinking feeling, and it feels very well made. Excellent value for the price. Highly recommend.

Amazing mattress!! So comfortable , a gang for the price. I’ve had it for a month and it’s as good as the first day. I thought it was just a mattress sized plushie since it came boxed but no, it’s a whole mattress. Get it!

was very easy to set up, expanded fully in 8 hours, I have never slept better, it's a perfect medium firmness, I have never had a memory foam hybrid bed but I am pleasantly surprised by the all around quality, have not experienced any back pain since

This is one of my first reviews- if you are considering this mattress BUY IT. I didn't spend a lot of time searching, I actually dreaded this process of finding a mattress online after a few bad ones but chose to go this route again for a queen size mattress for my parents RV that we would only sleep on a few times a year. I read the basic review summary and went with it(a first for me, I usually scan reviews)! I am SO SO happy with this purchase. First, its comfort level is right on. Medium Firm, it didnt even need memory foam. Both my husband and I are 5'9 and I weigh 150, he weighs 185, we also shared the bed with my 2 year old.. I didnt even feel my husband move from the bed both nights(im a super light sleeper). Length was great. I am so pleased with this mattress I will absolutely buy another one for our guest bedroom. I hope this review will help someone else searching for the right mattress. I will say, we should have let it air out from the bag when we received it, but my dad opened it and we did not have time to do that before sleeping on it. But, I didnt notice a smell I dont think, just wish I would have been able to let it air from the plastic.

I got the 10" mattress. It's not my favorite mattress, feels a little stiff for what I like but I needed more back support so I tried it. The price is good at $167 and I purchased a 4" memory foam topper to go on it... which makes me like the bed more. One of the sides of the bed was a little concave. I let it sit for the full time to inflate so that's the other reason the topper has come in handy.
