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. SupportAdjustable lumbar bar Capacity750 lbs total Height4", 8" or 12" legs ControlWireless remote Support for the Part of Your Back That Needs It Most Adjustable Lumbar Support BarStop 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. See the MechanismLumbar 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 PresetZero 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 MassageSoothing 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 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-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 Pearl's remote has a soft-touch finish and logically grouped buttons for positions, massage, lighting and memory.

How Pearl Compares in the baselogic™ Lineup Pearl is the only model in the baselogic™ family with an adjustable lumbar support bar, positioned between Gold and Platinum.

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. 20-Year Limited Warranty2 years full, 5 years parts, 20 years structural. Adjustable LumbarLower-back support you control from the remote.
