The Beautyrest® baselogic™ Pearl Adjustable Base adds something most bases in its class leave out: a lumbar support bar you can raise and lower from the remote. Pair it with head and foot adjustment, a zero-gravity preset, head and foot massage, soft underbed lighting and USB charging, and your bed becomes a place to read, work, recover and fall asleep in comfort.

When you sit up in bed, the curve of your lower back often floats unsupported, which is why a pile of pillows never quite feels right. Pearl's lumbar support bar lifts into that curve on command, so you can dial in firm, even support whether you are propped up with a book or lying flat for the night.
Unlike a head or foot section, the lumbar bar has its own motor in the middle of the base. It works independently of the other sections, so you can add lower-back lift to any position you create, including zero gravity or one of your saved memory presets.


Press Zero Gravity and the base raises your legs slightly above heart level while lifting your upper body. This neutral posture takes pressure off the lower back and joints, a favorite after a long day on your feet or a tough workout.
Gentle vibration in the head and foot sections helps your body let go of the day. Run both zones together or just one, and set a timer so the massage fades out on its own as you fall asleep.


The soft-touch wireless remote puts every Pearl feature a thumb press away, with clear groupings for position, massage and memory. It arrives already paired to your base, and a child safety lock keeps little hands from changing your settings.
Take the legs off and set the base inside most existing bed frames and platform beds for a clean, built-in look.
The base folds for easier delivery through doorways and up stairs, and for simpler storage if you move.
Rated for 750 lbs combined, including your mattress and bedding, when weight is spread evenly.
A mattress retainer bar at the foot keeps your mattress from sliding as the base moves.
Lower the base to flat during a power outage using two 9-volt batteries (sold separately).
Twin XL and Cal Twin bases include a sync cord and connecting strap so two bases move together from one remote.
Each 12" leg is made of stackable 4" segments. Keep them all for a taller bed, remove segments to match your nightstands, or take them off completely to use the base inside a frame.

Pearl is compatible with Beautyrest® mattresses, so you can pair it with a Beautyrest model you already love or shop for both together. Most adjustable-friendly mattresses from other brands will work as well; if you're unsure, check with your mattress manufacturer.
Split King and Split Cal King sets use two separate mattresses (2 Twin XL or 2 Cal Twin).
Pearl sits between Gold and Platinum, and it is the only baselogic™ model with an adjustable lumbar support bar.
