Rize Tranquility Adjustable Base

Rize Tranquility II: the platform-friendly base built around zero gravity

The Rize Tranquility II is the relax-and-recline adjustable base for people who want the comfort positions without the bulk or the long feature checklist. One touch drops you into a preset Zero Gravity recline, the position that floats your weight off your lower back, and a second touch sends the bed back to flat for sleep. Rize specializes in adjustable bases, and the Tranquility II is its comfort-forward pick: a clean, modern frame that slips under almost any mattress and gets the day off your back.

What you notice first, raising head and feet together, is how fast pressure leaves your lower back. The bed cradles you into a gentle V so your weight settles into the mattress instead of pressing down on it. That is what Zero Gravity does, and it is the position to test first.

What the Tranquility II actually does

• Zero Gravity, one touch: a preset weightless-feeling recline that takes the load off your spine, plus a One-Touch Flat return. Both positions are re-programmable, so you can set the buttons to your own favorite angles.
• Full head and foot range: head incline up to 64 degrees for reading, TV, and relief from snoring, congestion, and reflux; foot incline up to 34 degrees for tired legs and circulation. Roughly 65 degrees of movement end to end.
• Two heavy-duty motors: dual lift motors rated up to 850 lb per single unit, so the base moves a real mattress without straining.
• Wireless ergonomic remote: move between positions from bed and back to flat for sleep, no cords to fight.
• Backup battery and gravity-release: a backup battery keeps you supported in a power outage, and a built-in gravity-release safety feature returns the bed smoothly to flat if the power drops.

The part most adjustable bases get wrong: it fits

The Tranquility II is built thin on purpose. A 3.3-inch zero-clearance profile lets it sit right on top of a platform or pedestal bed, so you keep your existing frame and headboard instead of buying new furniture. Six stackable legs set the top-deck height anywhere from 3.3 inches to 16.3 inches, and it assembles with no tools. King and California King ship as one piece, not a split, if you want a seamless top across the bed. Measure your frame opening and your sheets before you order, and the showroom team will confirm the fit.

Who the Tranquility II suits

• shoppers who want a bed to decompress in, not just sleep on;
• anyone with lower-back tension or tired legs who would benefit from a nightly recline;
• platform-bed owners who want adjustable positioning without replacing the frame;
• couples upgrading a primary bedroom and wanting one unbroken King surface.

Honestly, it is not for everyone. If you only ever sleep dead flat with no interest in reclining or reading in bed, a fixed foundation may be all you need, and the Mattress Overstock team will say so. The Tranquility II earns its place when you actually want those positions.
