It's very easy to assemble, just 2 screws to fix the buttock support piece to the back support piece, then 2 screws to fix each handle rail to the back support piece as shown in the video. The mattress is then secure to the back support piece with the Velcro on the back of the mattress. That's it.
See below video guide on assembly
