Office Chair Mat 90 x 120 cm Non-Slip Polyester Water-Repellent, Also 60 x 90, 90 x 90 and 80 x 120 cm, Seven Colors | Sansoti

Four sizes, with 90 × 120 cm as the largest

With a chair mat, the size is the whole decision: too small, and your wheels roll off with every movement, damaging the edge. The largest option here is 90 × 120 cm, just over a square metre, keeping the entire chair base on the mat even when you roll backwards. The range also includes 60 × 90, 90 × 90 and 80 × 120 cm. The material is 100% polyester, machine-woven, with a plain surface, and the mat is non-slip, water-repellent and colourfast. Available in seven colours.

Sizes and features at a glance

• 90 × 120 cm: the largest size, for a workspace where you move both backwards and sideways.
• 80 × 120 cm: the same length, slightly narrower, for a desk against the wall.
• 90 × 90 cm and 60 × 90 cm: square or compact, for a smaller corner or a narrow study.
• Non-slip: stays in place on both carpet and hard floors, without double-sided tape.
• Water-repellent: moisture stays on the surface, so you can wipe it away before it soaks through.
• Colourfast: does not fade by a window or next to a lamp.
• 100% polyester, machine-woven: plain surface with no texture for the wheels to catch on.

Measure before choosing

A practical method: position your chair at your desk, roll backwards to the point where you would normally stand up, and measure that distance plus the depth of the chair base. That is the minimum length you need. In many home offices, this comes to between 100 and 120 cm, which is why the two longest sizes here are 120 cm deep. Choose the width based on how much you move sideways: 80 cm is enough for a single desk, while 90 cm is more comfortable for a setup with two work surfaces side by side. Place the mat with its long side perpendicular to the desk and slide the front edge underneath the desktop, so you do not step over it when sitting down.
