Harper & Bright Designs Upholstered Daybed with Pop Up Trundle, Twin to King Size Velvet Upholstery Daybed Sofa Bed with Armrests for Bedroom Guest Room, Gray

It feels sturdy enough when put all together as a couch/day bed but pulling out the bed underneath is a little difficult even with a 5" mattress. I hear the front board crack a little with each pull. I try to pull from the mattress itself so that the wood isn't being pulled away from the metal, it's effectively pulling on the metal frame instead. i recommend 5" Zinus foam mattresses! This bed is exactly what we wanted and do comfortable with those mattresses.

The trundle bed came in two separate packages and I was able to assemble it by myself, though really you'd want two people for assembly. It looks like the photo too! My only frustration was that my order came without hex nuts, but the seller has just sent me these. Very responsive and friendly.
