Your side of the bed
NM Duo Lifestyle Adjustable Base
A head-and-foot adjustable base built for two sleepers: the head end moves in two independent halves, each on its own 19-button wireless remote, with per-sleeper massage, Zero-Gravity and Anti-Snore presets and two memory slots. The foot end travels as one. Rated to 850 lb, standing 15″ (38.1 cm) in Queen. Backed by a 10-year warranty.
Key Features
A head section for each sleeper
The two halves of the head end rise on their own, or in step.
One foot section, moved together
The foot end lifts across the full width as a single piece — legs up is one shared movement.
A 19-button remote on each side
Two wireless handsets, left and right, each with a safety lock.
Massage, per sleeper
Left and right massage, each with its own timer, modes and intensities.
4 programmable positions
Memory 1, Memory 2, Anti-Snore and Zero-Gravity, each waiting on a button.
Dual USB hubs
Type A and Type C ports built in, one hub for each side of the bed.
Benefits
Two angles, no negotiation — one of you sits up with a book while the other stays down; the head sections are driven separately, so neither waits on the other.
A remote each — left and right handsets mean nobody reaches across the bed, and the safety lock keeps a stray press from moving the deck.
One press to the Zero-Gravity recline — the preset is stored on both handsets, so the deck takes its reclined shape without anyone dialling it in by hand.
A quieter side of the bed — Anti-Snore brings the upper deck to its set incline, and since each head half moves on its own, raising one leaves the other where it was.
Ideal For
Mismatched bedtimes
One of you reading at eleven, the other already flat, on the same bed.
A full-width Queen or King
One whole unit at standard mattress dimensions, rather than a pair of narrower halves.
Two evening routines
Separate massage settings on separate handsets, so each side closes the day its own way.
What Moves & What Powers It
What the base is made of, in four parts, beginning with the one that splits.
A head in two halves, a foot in one
Two powered sections at the head, rising individually or together; at the foot, one section across the full width. That division is what lets two people hold different positions on the same Queen or King.
What carries the mattress
A steel frame finished in non-skid fabric: the steel takes the load, the fabric stops the mattress travelling as the sections angle. The frame folds; the deck surface is spot clean only.
Three leg heights, per size
Heavy-duty 3-in-1 legs stand the Queen at 8.3″, 11.8″ or 15.3″ and the King at 9″, 12.6″ or 16″ — enough to reach a headboard or open the floor beneath. Assembly is minimal and needs no tools.
Two remotes, and a battery in reserve
Each 19-button handset is wireless and locks against accidental presses; the dual USB hubs sit on the base itself. A battery on board covers the emergency lowering when there is nothing coming from the wall.
Compatibility & Fit
Mattress pairing — works with any mattress marked Compatible with Adjustable Bed Base on its product page — most foam, hybrid and latex models.
A 3″ deck, in a frame or on its legs — the easy-fit profile is zero-clearance and needs no gap around it to work, which leaves two ways to set the Duo up: lowered into the bed frame already in your room, or standing on the 3-in-1 legs. A headboard bracket is available.
Queen and King, full width — the Duo arrives as one complete unit in either size, built to standard mattress dimensions so a single mattress lies across the whole deck. Per-size figures are below.

The Duo is covered by a 10-year manufacturer warranty. To start a claim, email support@nationalmattress.ca with your order number and photos or a short video of the issue — our team coordinates the rest with the manufacturer.
