I love this bed so much. We recently surprised my stepdaughter with a brand new bedroom when she returned from camp, and this was the center of it all. Putting it together definitely requires two people, but it’s not complicated. The back does have the same fabric as the rest, so feel free to float this day bed! We ordered the Alwyn 8 inch plush foam mattress for the top, and the 7 inch for the trundle. So comfortable! The bed came before all other furniture, so each night when we finished working I’d lay on it for an hour or so lol! The mattresses are a VERY tight fit, so I would choose a comforter rather than duvet and down setup if you’re planning to tuck it in for looks. Get plenty of big pillows and enjoy! 

P.S. Do NOT order twin xl mattresses! Just regular twins. Hope this helps!
