A low, rigid platform for your bed
MARSHALL® Boxspring — Posture Board 2″
The MARSHALL® Posture Board 2″ Boxspring is the thinnest foundation we carry — a low, rigid kiln-dried wood platform that lays a firm, flat surface under any mattress with almost no added height. Built in Canada in a clean grey upholstery cover, it suits platform beds, slatted bases, or a frame. Stands just 2″ (5.1 cm) tall, backed by a 10-year warranty.
Key Features
Slim 2″ profile
At just 2″ thick, it adds firm support with almost no added height — ideal when you want the surface, not the lift.
Rigid wood platform
A solid, kiln-dried wood board lays an even, full-surface base under the mattress; kiln-drying stabilises the wood so it resists warping.
Made for platform & slatted beds
Drops onto a platform bed, over a slatted base, or inside a frame to give the mattress a continuous, solid surface.
Clean upholstery cover
Wrapped in a durable, OEKO-TEX® Standard 100-certified fabric cover in grey that keeps the board finished.
Made in Canada
Built in Canada from FSC-certified wood, by the name behind the original pocket coil.
Benefits
Solid, even surface — the rigid wood board gives the mattress a flat, continuous base, corner to corner.
Support without the lift — at 2″, it firms up the base without raising the height of your bed.
Clean, certified materials — FSC-certified wood and an OEKO-TEX®-certified cover, built to last under your mattress.
Fits where you need it — sits on a platform bed, over slats, or inside a frame and supports any mattress type.
What’s Inside
How the board is built, and how to keep it.
Frame — kiln-dried wood
A solid, rigid wood board engineered as a low platform for even, full-surface support. Kiln-drying removes moisture so the wood stays stable and resists warping under the weight of the mattress.
Cover — upholstery fabric
A durable, OEKO-TEX® Standard 100-certified fabric cover in grey wraps the board for a clean, finished look that sits neatly on a platform or inside a bed frame.
Care
Do not wash or dry the board; vacuum it, and turn and air it out periodically to keep it fresh.
