    The Adjustable Base A4 adds massaging motors, USB ports, and two extra programmable presets to everything you already get with the A3. You still have smooth head and foot articulation, quick one-touch Zero-G and flat presets, and under-bed lighting, now enhanced with soothing massages in three intensity levels and dual USB ports to keep your devices powered. It’s a new take on luxurious comfort – built into one smart base.

     

    Wireless Remote Control for Adjustable Base Bed - Adjusted Independently - Synced for Divided Bases

    Head and Foot Articulation

    Elevate the head and/or foot of the base to fine-tune it and find the ideal comfort position. Ease out snoring and acid reflux (GERD); meditate and relieve back pain; read and watch TV while snug in bed.

    A Bed Built For Two

    When sleeping with a partner, the king-size base (two twin XL bases together) provides individual control over each sleeper's position, allowing them to choose how they want to position their side of the bed.

    Note: The two twin XL bases can also be synced to act as a single king base.

    Syncing Two Bases (optional)

    A Sync Cord is included with King-size bases (two twin XLs). The Sync Cord connects the two motors to a single remote for synchronizing the two bases.

    Note: When using synchronized adjustable beds, there may be an interval of up to 1.5 seconds between the movements of each bed.

    Syncing Two Bases - Two Sides - With Bed USB Remote

    Care & Maintenace

    Do Not Exceed Weight Capacity

    This product is not rated to support weights exceeding a total of 750 lbs, including the mattress and bedding. Exceeding this weight limit can damage the adjustable base, cause serious injury, and void the warranty.

    The base can structurally support this weight limit, provided the weight is evenly distributed across the adjustable base. The adjustable base is not designed to support or lift this amount only using either the head or the foot sections.

    New Product Odor

    Some people may notice a slight odor when they receive their new adjustable base. This odor is normal and usually dissipates before the product is delivered to you. Sometimes, this odor may still be noticeable and should dissipate after a few weeks.

    Break-In Period

    You can speed up the break-in period by simply spending time in the adjustable bed doing activities such as reading, sleeping, and watching TV. The extra movement will help the adjustable base respond to weight and temperature changes.

    Fabric Care

    To prolong the life of your fabric, protect it from direct sunlight whenever possible. Keep at a minimum of 12 inches (30 cm) away from direct heat sources.

    For spot cleaning, wipe the area with a light, damp sponge or vacuum with a soft brush attachment to remove particles.

    For a deeper cleaning, blot liquid spills with a clean dry cloth. Wipe with a clean cloth dampened with warm water. Do not wet excessively or use abrasive or harsh chemicals. A soft-bristle brush may be used to remove ingrained soil. Avoid scratching by gently brushing. Wipe with a clean cloth dampened with warm water to remove residues.

    Dry out of direct sunlight and away from direct heat sources. If persistent marks remain visible after cleaning, seek professional advice.

    Motors

    The massage motors are not designed to operate continuously for more than 30 minutes at a time. Please allow the massaging system to rest for 30 minutes after the automatic massage shuts off before restarting.

    Adjustable Base - A4 FAQS:

    The A4 builds on the foundation of the A3 Base with added features for a more premium experience. It includes everything from smooth head and foot articulation to one-touch presets for Zero Gravity and flat positions, but takes comfort further with dual massaging motors offering three intensity levels. You also get dual USB ports (for both A and C devices), two additional memory presets to save your favorite positions, and soft under-bed lighting for nighttime convenience. Like the A3, it includes gravity release for safe lowering, backup power-down, and a foldable frame for easy setup and transport.

    Zero gravity is a preset position that slightly raises your head and legs above the heart, so your body feels weightless. It was inspired by how astronauts are positioned during launch because that angle helps reduce pressure on the spine and distribute weight more evenly.

    For sleepers, this position takes stress off the lower back and hips, keeps the spine in a more natural alignment, and helps muscles relax. It also improves circulation by raising the legs above the heart, which can ease swelling and reduce pressure on sensitive joints. If you deal with snoring, acid reflux, or sleep apnea, the head elevation can make breathing easier as well.

    Outside of sleep, many people use zero gravity just to relax and watch TV or read a book. The posture helps you stay comfortable for longer without the soreness you’d normally start feeling if you stayed flat on your back.

    All of our mattresses work great on the A4 Adjustable Base. Our top recommendations would be the Latex Mattress, the Latex Hybrid Mattress, and the DIY Hybrid Mattress.

    Yes. Its slim 4" profile fits seamlessly between your mattress and base. You can also use the included 12" stackable legs for standalone support and underbed storage.

    Latex, memory foam, and hybrid mattresses are the best options. Innerspring mattresses with rigid, interconnected coils are not recommended, as they don’t flex well with adjustable movement. Water beds, air mattresses, and extra-thick or ultra-firm mattresses are also not recommended.

    The best mattress for an adjustable bed frame is an all-foam mattress. We recommend opting for an all-latex mattress, which is composed entirely of latex foam layers. It's eco-friendly, durable, responsive, supportive, and provides contouring and cushioning - a perfect complement to the flexibility offered by adjustable bed frames.

    The A4 Base supports up to 750 lbs, including the mattress and bedding. The weight should be evenly distributed across the base.

    Yes, but the setup is simple. The A4 Base comes mostly preassembled – you’ll just need to unfold it, screw in the legs by hand, plug in the power cords, and attach the mattress retainer bar. The process takes only a few minutes and doesn’t require any tools. Two people are recommended for safely turning the base upright.

    An adjustable bed frame can last 10 years or more, depending on how often it’s used and how well it’s maintained.

    You can attach your own headboard to the A4 Base using headboard brackets and the included hardware. Footboards, however, are not compatible with this model as they're fitted with a mattress retainer bar at the foot.

    The A4 Base has built-in power outage protection. If the electricity goes out, you can press the button on the power-down box located under the base, and it will safely return to a flat position.

    Yes, provided that you choose the right fit. Sheets with deep pockets (10" to 14" or more) work best, especially fitted sheets that stretch over the corners. For split king setups, you can even use separate sheets for each side to avoid tugging when adjusting positions.

    Do:

    • Plug your adjustable base into a surge protector.
    • Contact us for any technical issues.
    • Use with adjustable base friendly mattresses.
    • Lower to the flat (horizontal) position after use and in between presets.
    • Evenly distribute weight when sleeping in a split setup.
    • Register your warranty as soon as your adjustable base has been delivered.
    • Use mild soap and water to clean your adjustable base if it becomes stained.
    • Enter or exit your adjustable in the flat (horizontal) position.

    Don't:

    • Sit on corners/edges of base; this may warp the frame, struts, or foam.
    • Tilt the base on its side. This can damage the legs and/or leg screws.
    • Force the base down; this can damage the motors or frame.
    • Stand or jump on the adjustable base at any time; this can damage the frame and motors.
    • Drag the base to move it. Dragging the base could cause damage. Purchase castors if you plan on moving your base routinely.
    • Enter and exit the adjustable base with the head and/or foot in the articulated position.
    • Tinker with or modify the base. This will void the warranty.
    • Press down on the head or foot sections while actuated; this can damage the frame and motors.

    Not at all. The A4 Base is energy-efficient:

    • Zero standby power system keeps energy use under 1 watt when idle.
    • Motors only draw power when adjusting positions.

    Even nightly use won’t significantly affect your electricity bill, and the low-consumption design makes it a sustainable choice over time.

    Seniors often benefit the most from using an adjustable bed base.

    Head and foot articulation eases aching joints, provides pressure relief, reduces back pain, maximizes REM sleep, and can improve circulation.

    Elevating the head can make reading, watching TV, sleeping, and other activities much more comfortable for those with GERD or snoring issues.

    Smooth, silent motors make adjustments effortless, even for those with limited strength.

    No. Box springs aren’t designed to flex with an adjustable base. They’re rigid, which can damage the base and reduce mattress performance.
