I’ve always been wary of buying a sofa bed, will it last, is it easy to transform and is it durable to use as an everyday sofa and when needed a bed. 
The Mary-Kate is all that and more. As a sofa it is  more than big enough for 2 adults, the material is soft and easy to clean. It can adapt to a lounger just by pulling the straps and a lift up into place,.the backrest has 3 positions-straight slopped and flat (sofa,lounger and bed) Bedding can be stored underneath when not in use.  Most sofa beds have a maximum weight 100kg but this can take the weight up to 200kg(
I took the 5year protection out which covers everything I would expect to be covered and since it’s just me and the dog using it and the occasional use by grandkids it’s money well spent
