This mattress is GREAT! Second night my back pain went away. At 320lbs (male) it supports me better than my one year spring mattress it is replacing. This mattress comes in a box and the instructions say to let it sit for 48hrs. For me this was an investment so I followed said instructions. These mattresses in a box need to air out when you 1st unwrap them. Do Not put your new mattress in a protective cover. It will delete the purpose of airing out. Do Not use mattress for the manufacturer's recommended time frame. Just follow instructions for best possible outcome.

I also paired this mattress with Lucid's, L100 adjustable bed base. Both items were cheaper purchasing from Wayfair than the actual company. 

Thank You Wayfair for saving me money.
