Haven’t slept on this yet but it is comfortable to sit on.
I was able to assemble it by myself; for the back slats it was helpful to leave the slats’s screws a bit loose and to loosen the barrel bolts for the arms. The assembly directions were clear, all hardware was provided (including extra items), except for a screwdriver.
 Having read other’s reviews about the platform slats breaking, I bought thin ‘bunkie’ boards (https://www.wayfair.com/bed-bath/pdp/ebern-designs-terilee-019-folding-wood-bunkie-board-w110351421.html?piid=94373779). To put on top of the platform slats.

I had some difficulty figuring out how to collapse the trundle bed as the assembly instructions were a little lacking on this point. I emailed the manufacturer (Kodiak Furniture) and they were very helpful by sending me a video.

I think this daybed will offer me a lot of flexibility with house guests including tge ability to configure it as a king size bed.
