Most uncomfortable couch or futon ever.
There is wood down the middle and I plopped down on my couch and hurt my back by smashing my tail bone.
The fabric is sagging and it is a month old, gently used. 
I fully regret buying these. I bought two and they are horrible but didn't know how to go about returning two couches. 
Literally one of my worst purchases of all time.
We have people stay with us and we take these as beds to give guests the bed and the wood frame makes it feel like you are sleeping on a letter H with that bar right in your hips.
DO NOT BUY.
