The memory foam filling is the core of what makes this office chair back cushion effective. Unlike standard polyester-filled cushions that compress flat within weeks, slow-rebound memory foam maintains its shape and support over time — consistently filling the gap between your lower back and the chair back to keep your spine in a neutral, supported position throughout the workday.

The cotton patchwork cover is soft against the back and more breathable than synthetic fabric covers — reducing heat build-up during long sitting sessions. The solid colour design in Navy Blue or Silver Moon Grey is professional and understated, fitting naturally into any office or home workspace without looking out of place.

Who This Is For

• Drivers who want lumbar support during long commutes or road trips
• Students and gamers who spend extended hours at a desk and need better back support
• Anyone recovering from lower back strain who needs gentle, consistent lumbar support during seated activities

FAQ

Will this fit my office chair?
At 38x12x44cm, this cushion fits most standard office chairs, desk chairs, and car seats. It is designed to sit against the chair back and support the lumbar region. Most cushions of this type attach via a strap or sit in place by friction — check the product images for attachment details.

How is memory foam better than standard cushion filling?
Standard polyester or foam cushions compress flat over time and lose their support. Memory foam is slow-rebound — it conforms to the shape of your back under pressure, then gradually returns to its original shape when you stand up. This means consistent, personalised support that doesn’t degrade as quickly as standard filling.

Is the cover removable for washing?
The cover is made from cotton patchwork fabric. Check the product for a removable cover zip before washing. If removable, hand wash or machine wash on a gentle cycle. Do not wash the memory foam core — spot clean only.

What colours are available?
Navy Blue and Silver Moon Grey — both solid colours with a clean, professional look suited to office and home workspace environments.
