Buyer beware! Terrible quality control. Frame for the middle piece came in bent. Impossible to mount side panel. Slide out/sleeper section is wobbly and leaves too much room with side piece. I would have expected a better quality for $1150. 
I would not recommend getting this sofa from Wayfair or any other furniture.
Better to shop at local furniture stores in case if there are any issues. At least don't need to spend $100 to get your money.  
Garbage product!
