A smart sofa bed, was initially very pleased with it but after less than a year of owning it is now horrendously uncomfortable. Definitely not suitable for every day use, not unless you like the feel of frame and springs digging in to you! I'm fairly lightweight at 53kg, which only emphasises the lack of longevity and durability of the sofa. 
I would recommend buying, but only if it is lightly used and on an infrequent basis.
