The Serta® baselogic™ Pearl Adjustable Base goes beyond raising your head and feet. A motorized lumbar support bar presses gently into your lower back whenever you want it, joined by a zero-gravity preset, head and foot massage, underbed lighting, USB-A and USB-C charging and three memory presets, all controlled from one wireless remote.

Sitting up to watch TV or answer emails usually leaves a gap behind your lower back. On Pearl, the lumbar support bar rises right into that space, giving you steady, adjustable support that stays in place all night instead of shifting like a pillow.
A dedicated lumbar motor lifts the bar on its own, separate from the head and foot sections. Add it to a reading position, a lounge position or zero gravity, then save the combination to a memory button so it is one press away tomorrow.


The zero-gravity preset raises your knees and upper body into a weightless-feeling recline, with your legs lifted just above your heart. It is an easy way to ease pressure on your back and joints at the end of the day.
Quiet massage motors in the head and foot sections deliver a relaxing vibration while you read or settle in for sleep. Choose one zone or both, pick an intensity and let the timer turn it off for you.


Pearl's remote has a soft-touch finish and logically grouped buttons for positions, massage, lighting and memory. It comes paired to the base right out of the box, and the child safety lock prevents accidental changes.
Remove the legs to drop the base into most bed frames and platform beds, keeping the look of your current bedroom furniture.
The base folds in half, making it easier to carry through tight hallways and to store or move later.
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.
The 3-in-1 legs come assembled at 12" and are built from stackable 4" sections. Remove sections for an 8" or 4" height, or remove the legs altogether for a zero-clearance fit inside a frame.

Pearl works with Serta® mattresses, making it a natural match for a Serta you already own or a new one you are choosing now. Other adjustable-friendly mattresses generally work too; confirm with the manufacturer if you are not sure.
Split King and Split Cal King sets use two separate mattresses (2 Twin XL or 2 Cal Twin).
Pearl is the only model in the baselogic™ family with an adjustable lumbar support bar, positioned between Gold and Platinum.

Pearl keeps Gold's everyday features, from the wireless remote and zero-gravity preset to memory presets, underbed lighting, massage and USB charging, then adds a motorized lumbar support bar for extra lower-back support. If you need a split-head size, look at Gold instead.
Pearl supports up to 750 lbs total, counting the mattress and bedding, as long as weight is spread evenly.
Yes. An adjustable base is used in place of a box spring or foundation, so your mattress sits directly on it.
Pearl is compatible with Serta® mattresses. If you have a mattress from another brand, check with its manufacturer that it is suitable for an adjustable base.
Choose King if you and your partner are happy moving together on one 76" x 80" base. Choose Split King, two Twin XL bases with two Twin XL mattresses, if you each want independent positions and massage; the bases can also be synced to move as one.
Yes, using optional headboard brackets that are sold separately. There is no wall-hugger feature.
Setup takes a few steps: unfold the base, hand-tighten the legs, flip it upright with a helper, insert the retainer bar and plug it in. A surge protector is recommended.
*Foundation Not Required
