This review is for the Queen size adjustable bed. At 6' 2" and 320lbs it lifts me or rather props me up to read or watch TV with no problem. The legs go up too which is great. If there are any heavy guys out there looking for an adjustable bed "Go For It". As far as operational noise... QUIET. Assembly is a cinch. Attach the legs, plug in the remote's cable to bed and finally the power adapter into wall socket. That's it. I was able to do all this by myself but I would suggest having another pair of hands just for the sake of having them. If you live in an apartment with stairs/elevator or if this is going to the upstairs room in the house the second person will be needed. I matched this with 10" Medium Firm Latex Mattress from this manufacturer and they are fantastic together. After price matching online from different sites I found Wayfair to have the better price for both these items. Wayfair's price for the adjustable base was even cheaper than the company's. Thanks Wayfair.
