This sofa bed gets 5 stars on functionality, and space-saving features although it is smaller than another sofa bed in the house that only houses a twin-bed (!!), this one manages to stretch out an almost full-sized mattress (I say almost because it is a bit smaller than a standard full size mattress, BUT it does fit 2 people, which was the desired function). 

The reasons I dont actually give it 5 stars is because some of the aluminum pieces (2 of them to be exact) came a little bent at the end, so I had to hammer them a bit to straighten them, and also the mattress is extremely firmnot as comfortable (which can be easily fixed with a mattress topper).

Note it does come with the pillows in my picture - I just flipped them to the gray side to make them more neutral (they are the same design as the pillows shown in the product picture on Wayfair).
