Easy assembly. Took my husband 80 minutes. The trundle doesn’t attach to the bed frame, so you can set it up to come out of either side and it’s easy to roll in and out, even on carpet. The build is sturdy, but some pieces had minor imperfections (nothing structurally compromising). The slats for the trundle portion were difficult to screw in, and we didn’t like that there wasn’t a middle support rail for the trundle either (there is a support rail for the top, which is nice). The specifications say 5” mattress for the trundle, but we were able to easily fit an 8” memory gel mattress (which we also got from Wayfair and is super comfy). Overall, we are satisfied.
