No bad smell like some have reported.  Loft is more like 31/2 inches than 4.  But very comfy.  I bought this to use in our travel trailer.  The dinette makes a bed but is a little thin in the cushions. Planned on using this to beef it up yet still fold up easily.  So far I haven't been able to try it in the trailer because we keep using it on the livingroom floor while watching TV.  May have to get another!
