[This review was collected as part of a promotion.] We were really excited about having an adjustable base and were happy it could be delivered. The box was VERY large and extremely heavy though. My husband put it together mostly by himself but felt the instructions could have been a little clearer. However, after an hour of working on it, we found that the motors didn’t work at all. We went through all of the trouble shooting instructions in the manual, as well as looking online for help, but nothing worked. So now, we have a very heavy flat base. It does support the mattress well, and there is storage underneath, but we could have got that from a standard platform base for less.
