A solid foundation
NM Platform Base
The NM Platform Base is a folding platform foundation that gives any mattress the solid, flat support it needs — no box spring required. A plywood deck rides on height-adjustable steel legs and is finished with a black non-skid surface so the mattress stays put, standing about 11″ (27.9 cm) and backed by a 10-year warranty.
Key Features
No box spring needed
A solid plywood deck gives your mattress the flat, even foundation it's built for — on its own.
Folds flat
The platform folds in half for delivery, tight stairwells and storage between moves.
Height-adjustable steel legs
Sturdy steel legs set the bed height you want — stand it on its own or place it inside a frame.
Non-skid deck
The black non-slip surface grips the mattress so it doesn't shift or travel overnight.
Strong, quiet support
A steel-and-plywood build holds firm and even — none of the squeak or sag of an old box spring.
10-year warranty
Backed for the long haul on every size.
Benefits
One piece, simpler setup — the deck and its legs replace both a box spring and a separate frame, so the bed goes together fast.
Made for tight spaces — it folds flat to clear narrow doorways, stairwells and elevators — the apartment-mover's foundation.
Your mattress stays where you put it — the non-skid deck keeps foam and hybrid beds from creeping toward the footboard.
Set your own height — thread the steel legs to the height that suits your room, or take them off to drop the deck inside an existing frame.
Ideal For
Foam, hybrid & latex beds
Modern mattresses want a solid, flat base — not a slatted one.
Apartments & condos
Folds down to move in, then stores flat when you don't need it.
Box-spring replacers
A cleaner, lower-profile foundation with no squeak.
Want the bed itself to move? If you'd like to raise your head to read or your feet to relax, step up to the NM Lifestyle Adjustable Bases — the 1.0 Rise through 9.0 Ultra add powered head-and-foot articulation, presets and more.
How It's Built
Three simple parts, built to hold a mattress flat and stay out of the way.
Folding plywood platform
A solid plywood deck — not slats — spreads weight evenly and supports the whole mattress, then folds in half so it fits through tight spaces and stores flat.
Height-adjustable steel legs
Sturdy steel legs thread in to set the bed height, so the base stands on its own without a separate frame — or comes off to sit inside one.
Black non-skid deck
The deck's non-slip top surface grips the underside of the mattress so it holds its place night after night.
Compatibility & Fit
Works with any mattress — gives foam, hybrid, latex and innerspring mattresses the solid, flat foundation they're designed for, in place of a traditional box spring.
Stands alone or inside a frame — on its adjustable legs it needs no separate frame; take the legs off and the deck drops straight into an existing bed frame.
Folds for delivery & moving — the folding deck clears tight stairwells, doorways and elevators, then tucks away flat when it's not in use.
