RTG Sleep 3900 King Adjustable Base

This base is designed with a "zero clearance" low-profile foundation and height-adjustable legs, making it exceptionally versatile. It is engineered to be compatible with most decorative bed frames, including platform beds and those with slat systems. Because it can function without legs directly on a flat surface, it is a perfect solution for modern, low-profile bed designs.

The dual massage system provides targeted relaxation for both the upper and lower body. The integrated wave technology goes beyond standard vibration by creating a rhythmic motion that helps to soothe sore muscles and increase blood flow. This feature is particularly effective for those with active lifestyles or those who experience evening restlessness, as it helps transition the body into a state of deep relaxation before sleep.

Yes, the included wireless remote features a dedicated anti-snore preset. This position gently elevates the head to help open airways and improve breathing. By using this ergonomic adjustment rather than just stacking pillows, you can achieve a more supportive angle that reduces the likelihood of snoring without putting undue strain on your neck.

Yes, this is a standard, single-piece king adjustable base. Choosing a single base is ideal for couples who prefer a seamless sleeping surface without the "cuddle gap" often found in split king setups. This configuration allows you to use standard king-sized sheets and ensures that the entire mattress moves in unison, providing a consistent feel across the bed.

The zero gravity preset on this base is designed to mimic the weightlessness experienced by astronauts. By elevating your head and knees slightly above your heart, it helps to decompress the spine and reduce pressure on the lower back. This posture also promotes improved circulation and can reduce swelling in the legs, making it a highly recommended setting for recovery after a long day on your feet.

Despite its sturdy construction and dual motors, this base features a foldable design. This makes it much easier to navigate through tight hallways, around corners, and into elevators, which is a significant advantage for urban apartment living or frequent relocators. Once in the room, it unfolds quickly for a straightforward setup.

This base is built for the modern home, featuring both a wireless remote and mobile app compatibility for effortless adjustments. For safety and convenience in the dark, it includes a built-in flashlight on the remote and soft under-bed lighting. These thoughtful additions ensure you can navigate your room at night without needing to turn on bright overhead lights or disturb your partner.
