Head & Foot Articulation
RIO 4.0 offers the flexibility to elevate the head and/or foot of your adjustable bedframe to ease joint pain, reduce snoring, or simply relax with a book or movie.
Three Programmable Presets
Three of the buttons on your wireless remote are easily customizable to keep your favorite presets a touch away.
Under-bed Lighting
Soft LED lights under your bed help guide you through the dark as your feet address the floor.
Wireless Remote
A modern and stylish design makes this device the perfect go-to companion to articulate the bed, or one-touch functions like Zero Gravity.

Relaxation Mode
Two low-noise massage motors help you unwind in the comfort of your home. These powerful massage motors enhance circulation, muscle recovery, and meditation.

Zero Gravity
This dedicated feature raises the head and legs slightly above the heart to promote circulation and relieve lower back pressure. A NASA-inspired weightless experience, now available from your bed.

Dual USB Ports
Ergomotion’s sleek designs allow customers to charge their USB A & C devices while keeping cords tucked away.

One-Touch Flat Preset
With the press of a button, gravity brings the bed back to a flat position so you can get into and out of bed with ease.

Zero Clearance
The sleek, practical design keeps motors and linkages in a position where they do not interfere with under-bed storage, bed slats, or support.

Exactly as pictured, fabric feels higher quality than the price suggests. Would recommend to anyone considering the Ergomotion RIO 4.0 Smart Adjustable Bed .
Comfortable and well built, assembly was straightforward.
Sturdy frame, no wobbling after a few months of use. Wish it came with a carrying case but that's a minor gripe.
Looks great in our living room and several guests have asked where we got it. Would recommend to anyone considering the Ergomotion RIO 4.0 Smart Adjustable Bed .
Sturdy frame and the fabric feels premium. Assembly took a bit longer than expected but works great.
Comfortable and looks even better in person than in photos.
