Easy set up and quality materials.  It's clear the designers wanted to make a bed more than a sofa. Pulled out as a bed is like heaven with or without a mattress topper.  As a sofa, it's attractive though a bit stiff, but who cares when it's going in a guest room where you need a spare bed, but don't want to take up all that space with a traditional bed.... or annoy your guests with those bars in the middle of tuck under pullouts. 

Delivery speed was acceptable and service on delivery was great.
