Head, pillow, lumbar, foot
NM 9.0 Ultra Lifestyle Adjustable Base
The NM 9.0 Ultra Lifestyle Adjustable Base is the top of the Lifestyle line — it moves in four places: head, foot, pillow tilt and lumbar. Zero-Gravity, Anti-Snore and One-Touch Flat presets, 4 memory positions, massage and app control. Rated to 850 lb in every size, standing 15″ (38.1 cm) in Queen. A 10-year warranty.
Key Features
Four points of adjustment
Head and foot articulation, plus adjustable pillow tilt and lumbar support — the deck shapes along your body, not only at the two ends.
Three presets, four memories
Zero-Gravity, Anti-Snore and One-Touch Flat, plus four positions you program yourself.
Massage, three ways
Three modes across three intensity levels, on a timer that switches itself off.
Runs from your phone
Every function is reachable from an Apple or Android device, or from the 20-button wireless remote.
Type A and C charging
Dual USB hubs put the charging point where the phone already spends the night.
Light under the frame
LED under-bed lighting throws a low glow at floor level once the room is dark.
Benefits
The lower back gets its own control — the lumbar section rises independently of the head and the foot, so you decide how much the small of your back is held.
Weight spread wide — Zero-Gravity opens the angle at the hips and knees and lets the whole length of the deck carry you.
Anti-Snore at a single press — one button tips the upper section to its set angle — no hunting through controls in the dark.
Level again in one move — One-Touch Flat returns every section from wherever you left it, and four memories bring back the angles you actually use.
Ideal For
In-bed readers
Pillow tilt sets the head angle separately from the backrest, for books, laptops and long episodes.
Two sleepers, two angles
Two Twin XL units under one bed, with each half answering to its own settings.
Wind-down routines
Massage on a timer, a light under the bed and Zero-Gravity at the end of a long day.
What Moves & What Powers It
Pull the cover back and it comes down to four pieces of hardware.
The articulating deck
Four sections move — head, pillow tilt, lumbar and foot — and each takes its own angle anywhere between fully level and sitting upright.
Steel frame, non-skid cover
A steel frame under a non-skid fabric cover that keeps the mattress sitting where you put it as the deck bends. Safe-locking, zero-clearance and easy-fit, and it folds down to get through doorways and stairwells.
3-in-1 heavy-duty legs
Set the frame at 8.3″, 11.8″ or 15.3″ — 9″, 12.6″ or 16″ on King — to line up with a headboard or clear whatever lives underneath.
Power and safety
An onboard battery keeps enough charge to bring the deck back to level if the power cuts out, and the whole base goes together with no tools.
Compatibility & Fit
Mattress pairing — works with any mattress marked Compatible with Adjustable Bed Base on its product page — most foam, hybrid and latex models.
In a frame or on its own legs — the deck is zero-clearance, so no allowance has to be made around it, and either setup is fair game: lowered into a compatible bed frame, or up on the 3-in-1 legs. An optional headboard bracket attaches a headboard directly.
Split King — put a Twin XL on either side and together they stand at King width; pairing them takes the sync wires that come with every Twin XL, and a split base leg connector is available to lock the two frames as one.

The NM Ultra ships with a full document set — installation, remote and leg-height guides plus the manufacturer warranty, all one click below. (The platform name on these guides is Tranquility — that is the Ultra.)
Fabric deck: spot clean only — mild soap on a damp cloth.
Keep the space under the base clear so the mechanism travels freely.
Snug-check legs and headboard-bracket hardware after the first month, then twice a year.
Use a flexible, adjustable-rated mattress (memory foam or pocket coil) on top.
Troubleshooting basics
No response: reseat the power cord, verify the outlet, and test without a power bar.
Fresh remote batteries cure most missed commands.
Unplug 30 seconds, replug — the control box resets.
Beyond that, the installation guide above covers model-specific checks — or email support@nationalmattress.ca with your order number.
Warranty
The Ultra carries a 10-year manufacturer warranty (full terms above). To claim, email support@nationalmattress.ca with your order number plus photos or a short video — we coordinate with the manufacturer for you.
Parts & service
Replacement remotes, power supplies, legs and add-ons (headboard brackets, leg kits, sync cords) are available through National Mattress. For coverage past the manufacturer warranty, ask about the 10-Year Adjustable Base Protection Plan.
