[EX Q]: I ordered a king This mattresses is super comfortable, the measurements provided online were accurate. I was really nervous about ordering one I couldn’t try out but I went to a mattress store previously to try them out. I tried a hybrid mattress I fell in love with that was about $1500 but I just couldn’t pay that much for a mattress right now and it feels just like this one, I’m super pumped, it is sooooooooo soft but not to soft. 😁
[EX A]: positive
