I assembled a LOT of furniture this week and I dreaded assembling this daybed because normally the hardware is inferior and strips of never aligns well.  We’ll not this day Em and trundle.  All the hardware was high quality and screwed in effortlessly without the risk of cross threading. The wooden pieces fit together well and after assembly, it’s a sturdy and nice looking daybed.  We put an 8” memory foam mattress on it and it fit perfectly.
