This sofa bed is perfect for my woman cave/exercise room/spare room!  The bed is very! well made, sturdy, yet light weight enough to move around, we put sliders under the legs so as not to scratch the floor.  I used 8.5 inch mattresses on both top and bottom, the bottom is a tight fit with the 8.5" but I will have no bedding on the bottom (besides fitted sheet) unless it needs to be pulled out and used.  Shipping was quicker than expected. My partner put this together in maybe 2-2.5 hours.  A Win Win for me!!
