Most office chairs are designed for a fixed desk height that may not match your leg length — the result is hours spent with feet dangling slightly above the floor or with knees at an angle that compresses circulation. An under-desk foot rest brings the floor up to meet your feet, supporting a 90-degree knee angle that maintains circulation through long sitting sessions. The D-1 is an adjustable height foot rest with a rocking or tilting surface that adds gentle foot and ankle movement to a stationary working day.
The D-1 Performance Pillars
The D-1 sits under a standard desk and provides an adjustable elevated platform that brings the floor surface to the correct height for your leg length — supporting a neutral knee angle during seated work.
The correct seated position has thighs parallel to the floor and feet flat on a surface — but most desks and chairs are not perfectly matched to individual leg lengths. A foot rest closes this gap. The height adjustment on the D-1 lets you set the platform to exactly the right level for your chair and desk combination. The adjustment range covers the typical gap between floor and correct foot position for most adult heights.
The D-1 surface tilts or rocks during use — providing continuous gentle foot and ankle movement that maintains circulation in the lower legs during static desk sessions.
A fixed flat foot rest is better than no foot rest but still creates a static contact position. The tilting surface on the D-1 allows the feet and ankles to move naturally during a session — rocking forward and back, shifting weight, changing ankle angle. This movement maintains circulation in the lower legs and feet — the area most affected by prolonged sitting — without requiring you to stand up or interrupt your work.
The D-1 non-slip surface keeps the feet stable on the platform and the non-slip base keeps the unit stable on the floor — maintaining position under the desk throughout a working session without needing to reposition.
Foot rests that slide away from you during use are a known frustration — you repeatedly push them back into position, which disrupts focus. The non-slip base on the D-1 maintains position on hard floors throughout a session. The non-slip top surface keeps feet from sliding forward on the platform. Confirm material specifications with your supplier.
The D-1 stores flat under the desk when not needed and weighs under 1kg — it can be moved between desk setups, carried in a bag for use at different locations, or stored away completely when not in use.
Lightweight and flat profile means it is genuinely portable — not just theoretically portable. You can take it to a second desk in a different room, use it at a kitchen table for a working session, or pack it for travel. No assembly required — place it under the desk and use it.

Instruction guide
The D-1 pairs with The Zero-Equipment Athlete blueprint which covers desk worker posture principles and how to set up a home office that supports healthy sitting posture throughout a full working day — available with your order.
Before You Use:
Ensure the foot rest is stable and fully adjusted before placing weight on it. Do not use as a step or stand on it with full body weight — it is designed for seated foot support only. Check maximum load rating with your confirmed supplier before publishing. Keep away from children.
