AFS‑TEX® 4000X Black Active Anti‑Fatigue Mat 50 x 76cm

A compact Premium Standing Desk Mat engineered for active standing

The AFS‑TEX® 4000X is a space‑efficient premium standing desk mat designed for users who want the ergonomic benefits of active standing without requiring a large footprint. Its contoured, non‑linear surface helps reduce fatigue during prolonged standing, improving comfort and posture at height‑adjustable desks in both office and home settings.

At 50 x 76cm, this model offers a smaller working area than the 3000X while retaining the same focus on long‑term support, stability and durability.

Made for Natural Movement Throughout the Workday

The 4000X is designed specifically for the demands of standing desk use. Its active, contoured surface encourages continuous, subtle shifts in foot and ankle position. These micro‑movements help stimulate circulation, reduce joint strain and limit the static posture that often causes discomfort.

Ergonomic benefits

• Supports feet, knees and lower back during extended standing
• Encourages posture variation and micro‑movement
• Helps maintain focus by reducing physical fatigue

The compact size also suits smaller workstations or home office setups where space efficiency matters.

Active Features for Enhanced Foot and Ankle Mobility

Several raised features are integrated into the surface to support movement and stretching throughout the day.

Built‑in functionality includes:

• Raised ergonomic surround for controlled rocking and stretching
• Ergo‑bar and rear recess to facilitate ankle‑flex exercises
• Non‑linear contours that guide natural foot movement

These elements work together to provide the benefits of an active anti-fatigue mat in a more compact profile.

Durable Cushioning That Retains Its Support

A high‑gauge polyurethane core forms the heart of the mat, offering reliable cushioning that does not flatten or break down with regular use. The fine polyester cover provides tactile comfort and withstands daily wear.

Construction details

• Approx. 20mm cushioning depth
• Engineered to maintain its supportive structure over time
• Comfort‑oriented surface suitable for use with or without footwear

This combination makes the 4000X an excellent option for users who prefer to invest in durable, long‑term equipment.

Stable, Safe and Easy to Position

Stability is essential for standing desk accessories, and the 4000X’s non‑slip base ensures secure placement on most hard floors and carpet tiles. The mat also includes an easy‑slide profile to help reposition the mat during sit‑stand transitions.

Safety and usability features

• Anti‑slip base for dependable stability
• Compact footprint for smaller work areas
• Designed for quick adjustment between standing sessions
• Hanger hole for storage

Bevelled edges further minimise trip risk and allow smooth migration on and off the mat.

Built‑In Anti‑Microbial Protection

An integrated anti‑microbial ingredient protects the mat from microbial deterioration throughout its lifespan. As the protection is built into the material, it does not wash away or reduce with cleaning.

Hygiene benefits

• Effective 24/7 for the life of the mat
• Supports barefoot use
• The polyester cover allows easy surface cleaning

This helps maintain a cleaner, more hygienic working area.

Size and Colour

• Size: 50 x 76cm
• Colour: Black
• Shape: Rectangular

The black finish blends easily into both commercial and home office environments.

Ideal Applications

The AFS‑TEX® 4000X is well-suited to:

• Smaller sit‑stand desks
• Home office workstations
• Compact commercial work areas
• Users who prefer an active cushion mat without the footprint of a larger model

Its ergonomic design and smaller size make it a practical choice for users seeking reliable, high‑quality support in limited spaces.
