Adjustable Lumbar Support

Easily adjust the amount of lumbar support in your bed at the touch of a button to fine-tune your support to your needs. Maximize your sleep health and pressure-relief by ensuring your bed supports you just right.

Weightless Pressure-Relief

Zero Gravity mode puts you in a position where you feel weightless, taking much of the pressure off of your lower back to help you rest and recover form the day.

Improved Circulation

Raising the feet section or lounging in Zero Gravity mode lifts your legs above your heart, greatly improving circulation and relieving pressure from your legs which can help prevent blood clots, varicose veins, DVT, and others conditions.

Therapeutic 3D Wave Massage

Offers therapeutic massage modes with different intensities using 3D wave technology to provide calming sensations and full-body relaxation.

Adjustable Lumbar Support

Make on-the-fly adjustments to your lumbar support at the touch of a button so you can fine-tune to your needs and stay supported while the head section is raised.

Weightless Zero-Gravity

Zero gravity mode makes you feel weightless — taking pressure off the lower back, improving circulation, and positioning you for the perfect cozy night in.

Separate Head & Feet Adjustment

Allows you to raise and lower the head and feet sections independently, and bends at the knee to match your body's natural resting position and promote circulation.

Recommended by Doctors

Tested and recommended by our head of product development, Dr. Rick Swartzburg, D.C. — as well as a growing list of doctors and healthcare workers alike.

Adjustable Leg Heights

The legs come in segments allowing the total height of your base to be adjusted during installation, so your bed can be as high or low as you like it.

Zero Clearance

Zero clearance allows the legs to be completely removed so the base can be placed into almost any platform bed frame even with drawers or other storage.

Heavy-Duty Motors

Heavy-duty motors lift up to 850lb (per side in split king sizes) so you don't have to worry about your base giving out on you like cheaper alternatives.

Four USB Ports

Four convenient, easy-access USB ports (2 on each side) so you don't have to get out of bed to charge your phone, tablet, or other device.

Under-Bed Lighting

LED under-bed light illuminates your path in the night without disturbing your partner's sleep, so you don't have to trip over objects in the pitch black darkness.

BackFlex™ 2 adjustable base with edge-to-edge lumbar support

Get the Support You Need

Edge-to-edge lumbar support feature allows you to instantly adjust your level of lumbar support with the touch of a button, so you can fine-tune it to your exact needs!

Therapeutic 3D Wave Massage

Therapeutic vibration massage sends waves of soothing vibrations and relaxation throughout the bed, releasing stress and tension from your mind and body.

Zero Clearance & Adjustable Height

The base's legs come in sections which can be easily added or removed during installation to adjust the total height of your bed, so you don't have to worry about a thicker mattress making the bed too tall. Zero clearance mode even allows the legs to be completely removed to sit on top of platform bed frames or storage beds with drawers.

Adjustable Lumbar Support

Edge-to-edge adjustable lumbar support allows you to easily and instantly fine-tune your back support at the touch of a button. Whether you're sitting up, relaxing in zero gravity, or laying flat to sleep, BackFlex™ 2 makes sure you have the right support, every time.

Steep Head & Foot Incline

Fully separate head and feet elevation allows for up to 60 degrees incline on the head section and 40 degrees incline in the foot section.

Under-Bed Lighting & USB Ports

Under-bed light dimly lights your way at night so you can see where you're walking without waking your partner up or turning on bright lights. Dual USB ports allow you to easily charge your phone, laptop, or other devices without leaving the comfort of your cozy mattress.

Fits in Your Current Bed Frame

No need to toss the bed frame you love, our adjustable bases fit almost any bed frame! The adjustable base has its own legs and slots right into your frame where the mattress goes, instead of the box spring or slats your frame has now. Zero-clearance more even allows it to go right on top of platform beds and storage beds with drawers.

Stands the Test of Time

Durable, high-quality construction uses high-grade steel and strong, resilient motors to make sure your adjustable base will keep you sleeping happy for years to come, and not give out like cheaper alternatives.
