## Description

Product description

Review: Comfy for a 5'5" 120 lb person, more medium soft - This mattress is so so comfy and cushy! At the time of this review my mattress is still not fully expanded, it's only been 24 of the 72 hours recommended for full expansion. However I'm laying on it now because it beats sleeping on an air mattress, and I read somewhere that you can sleep on a hybrid mattress after 24 hours of expansion, and it will continue to full expansion without harming the mattress, so perhaps do your own research but I'm going with it. But yeah, I am a 5'5" 120lb female and a single sleeper, and this suits my frame well! The mattress is more in medium soft side to me, but it's firm enough support where Im not sinking in, and the pillow top is really nice and coushy and cradles just slightly - so it's cozy not sinking ,But I'd definitely let it expand for at least 24 hrs, I opened it at 8pm last night, and for sure I saw a big difference in the the look of it once I got home from work tonight, it's about 9pm the next day. No smells to me, just a nice fresh expanded mattress! Its also has handles, and is pretty easy to move around by myself. It's great!
Review: Good mattress - We’ve been sleeping on this mattress for about 3 weeks and it is so comfy. I have fibromyalgia and it hasn’t caused any flare ups or anything.
