I had this bed for 2 weeks and the quality is very good, is firm but not a rock. Super comfortable! 

BE AWARE! if you need it for an ottoman frame bed, SPECIFY THIS to wayfair, looks like the manufacturer produce them handmade, my 2 mattresses came 950mm wide instead of the 900mm wide specified as overall. They didn´t fit on my ottoman frames (even if there was a clearance on the inside of the frame of 920mm), so it was very painful as wayfair had to order a new ones, and amend another delivery for pick the first ones... it took a few days...
