A real lift at a lower line
NM Boxspring — White — Low Profile 4″
The NM White Low Profile 4″ Boxspring is a solid wood foundation that keeps overall bed height in check under today's thicker mattresses — a true foundation lift at a lower line, with easier sitting down and standing up. It stands 4″ (10.2 cm) tall, pairs with any mattress, and is made in Canada with a white non-slip stretch-knit top.
Key Features
Low-profile 4″ height
Trims the total height of the finished bed under a thick mattress, while still giving it a genuine foundation to sit on.
Solid wood frame
A rigid, solid-wood build that holds the mattress flat and evenly supported from edge to edge.
Non-slip stretch-knit top
The smooth, non-quilted stretch-knit surface grips the mattress base so everything stays squarely in place.
Vented base
Ventilation built into the foundation lets air move freely through the base of the bed.
Corner guards included
Reinforced guards on every corner protect the white cover where frames and rails make contact.
Benefits
A lower, cleaner bed line — with a tall modern mattress on top, the finished bed settles into a lower-slung, modern profile.
Easy in, easy out — the 4″ height puts the top of a thicker mattress right where sitting down and standing up feel effortless.
A true foundation underneath — solid wood across the full footprint carries the mattress flat and even, season after season.
Built clean, built here — made in Canada and built to meet or exceed provincial and federal fire-retardancy standards.
What’s Inside
How this foundation is put together — and how to look after it.
Frame — solid wood
A solid wood frame gives the foundation its whole structure: flat, rigid, and vented so air can move through the base. Corner guards reinforce every corner where a bed frame makes contact.
Cover — white polyester
The frame is wrapped in a white polyester cover with a non-quilted, non-slip stretch-knit fabric across the top — a clean finish that grips the mattress and meets or exceeds provincial and federal fire-retardancy standards.
Care
Spot clean only — a light spot clean keeps the white cover looking its best under your mattress.
