Purple adjustable bases fit inside most modern bed frames. However, they may not fit inside antique bed frames or other non-standard frames. We recommend you measure the inside of the bed frame and compare to the measurements below before you purchase.
When the Premium Plus base is placed within a bed frame, sometimes the motion sensor can become blocked. If you are using the base "zero clearance" with the legs removed, the motion sensor will need to be removed, as it extends below the frame. The motion sensor comes pre-installed on the base.
