Guests mattress is with us more often in use and is always praised. The cushion of the 3-part mattress can not rudely drop to the floor the user. The foam is good sound, not too soft but also not hard. Wonderful to relax. The cover is made of a gray (dark blue would be nice!) Cotton (80%) / polyester fabric (20%), which is washable at 60 °! When folded, the mattress can also be used as seating. All in all a great guest mattress!
