Serta® baselogic™Adjustable Lumbar SupportMassage & Underbed Lighting20-Year Limited Warranty

Lift, Lounge and Sleep With Built-In Lumbar Support

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.

Support for the Part of Your Back That Needs It Most

Stop Stuffing Pillows Behind Your Back

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.

Up to 40% better lower back support and improved spinal alignment, according to the manufacturer.

Lumbar Moves Independently

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.

Unwind in Your Favorite Position

Zero-Gravity Preset

Zero Gravity With a Single Press

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.

Single Massage

Soothing Massage for Head and Feet

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.

  • Head and foot zones, each with low, medium and high intensity
  • Timer for 10, 20 or 30 minutes, shown by lights on the remote
  • Auto shut-off after 10 minutes if no timer is set

Handy Features for Every Night

Underbed lighting on the Serta baselogic Pearl Adjustable Base

Underbed Lighting

Underbed lighting casts a gentle glow along the floor, making late-night trips safer and setting a calm mood at bedtime. It turns on and off from the remote.

USB-C charging port on the Serta baselogic Pearl Adjustable Base

USB-A & USB-C Charging

Built-in USB-A and USB-C ports keep phones and tablets charged within arm's reach, freeing up nightstand outlets.

Simple Control From a Wireless Remote

Serta baselogic Pearl Adjustable Base wireless remote

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.

Made to Fit the Way You Live

Zero-Clearance Profile

Remove the legs to drop the base into most bed frames and platform beds, keeping the look of your current bedroom furniture.

Folds in Half

The base folds in half, making it easier to carry through tight hallways and to store or move later.

750 lb Capacity

Rated for 750 lbs combined, including your mattress and bedding, when weight is spread evenly.

Retainer Bar Included

A mattress retainer bar at the foot keeps your mattress from sliding as the base moves.

Battery Backup Strap

Lower the base to flat during a power outage using two 9-volt batteries (sold separately).

Pairs for Split Sizes

Twin XL and Cal Twin bases include a sync cord and connecting strap so two bases move together from one remote.

3-in-1 Stackable Legs

Pick the Height That Suits Your Room

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.

Mattress Compatibility

Built to Pair With Serta® Mattresses

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).

Frequently Asked Questions

Why choose Pearl over the baselogic™ Gold?

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.

What is the weight limit?

Pearl supports up to 750 lbs total, counting the mattress and bedding, as long as weight is spread evenly.

Does it replace my box spring?

Yes. An adjustable base is used in place of a box spring or foundation, so your mattress sits directly on it.

Which mattresses can I use?

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.

Should I get a King or a Split King?

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.

Does it work with a headboard?

Yes, using optional headboard brackets that are sold separately. There is no wall-hugger feature.

How hard is setup?

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.
