I really like this little convertible sofa!  It's not the softest thing in the world when lying down, but with a memory foam cover for guests, it'll do just fine.  It's pretty firm for sitting but I actually don't mind that for just sitting.  My friend who is 5'7" played down on it to see if she could fit and it was just fine for her.  Not sure my 6'1" husband would sleep all night comfortably, but he was happy laying there curled up with our dog for 15 minutes.
