OK, so you're interested in an adjustable base. Let me start by saying this one is great. It's sturdy, relatively quiet (except the massage which is thunderstorm loud on hard floors) has great features. One minor complaint is that you need to press a key on the remote before it lights, so if you don't have the keys memorized it's not real helpful. It would be great if the remote would illuminate by motion sensing like modern tv remotes. So now onto the important part. It's amazingly heavy, the king comes in two pieces with the separation between the center of the head and foot, opposite of the split king. We had three people and it was all we could do to lift and carry each half. After assembly the weight doubles. The connections could have been a bit more clear, the manual says they are color coded but matching orange to red isn't a match...confusing. Once we got it lifted up and on its side we lifted one end and got a shower towel under the leading end and used it to help drag the base into position in front of the bed frame. We couldn't dead lift the base once assembled and if you roll it into the legs they can bend or break. We attached the 3 legs on the side that was towards the ceiling and left them off the side near the floor. Next we placed a heavy redwing crock in front of the side without the legs and rolled the bed over it so the side with legs ended up on the floor and the other side was suspended by the crock which was high enough to allow the legs room to be screwed in. Then once the legs were mounted we lifted that end and removed the crock. At this point 3 of the 6 legs were inside the bed frame and 3 outside. We finished by lifting and sliding the base to get the remaining 3 legs over the frame and in place. I should mention we added felt floor protector pads to all 6 legs. Truly, if white glove service is available I would highly recommend it. It was not available due to COVID. I hope this helps someone, we expected this to be heavy but truly were not prepared for the reality of the weight and awkward handling. Note before the two halves are locked together and also somewhat after, the metal frame moves and can pinch or smash your hands, so be mindful your not lifting from a part that moves.
