This is a great Sofa bed, the click clack feature is so convenient and not a massive effort each time you are transforming the sofa.  I did see in previous reviews you cannot really sleep on this sofa without a memory foam mattress topper and after two weeks straight of regular use I must agree, I since picked up a mattress topper from Wayfair and it has improved the overall comfort level by a factor of ten. I am using this due to limited space but as spare room sofa i think this product would be perfect (as long as your guests are under 6 foot).
