The wall bed is a wonderful product and well designed. I think having the two pistons on each side of the bed mechanism makes me more confident that should one stop working it'll still function just as well. Having the multple backboards is also nice since you have lots of options for securing the wall bed to studs behind should the recommend topmost and bottommost sections not be ideal.

Only complaint was that the delivery through Wayfair did not include the bed mechanisms on initial delivery (3 boxes per wall bed, 2 boxes for the wood/frame plus one for the bed machanism) and took ~1.5 months before they could sort out the issue and deliver the missing box for each wall bed purchased. But ultimately Wayfair was able to resolve and delivery the missing boxes.
