## Before you buy

- The feature text gives dimensions as 46 × 36 × 7.5 cm, while the details table lists only 36L x 46W centimetres. The same listing describes firmness as both medium and medium-firm, and labels the shape both U-shaped and semicircular. Confirm the exact version and fit before buying. The suggested user weight is around 70–100 kg, and the maker advises measuring the chair.

## A good fit for

- People wanting an extra memory-foam layer on a desk, office or dining chair.
- Drivers or wheelchair users looking for a cushion that can be moved between seats, if its dimensions fit.
- Adults who prefer a medium or medium-firm seat cushion and can follow the cover-only washing instructions.

## Less suited to

- Buyers needing a washable foam core or a cushion with an unambiguous shape and firmness specification.
- Anyone whose chair is narrower or otherwise incompatible with the stated footprint.

## Customer feedback

Customer feedback highlights comfort, cushioning, support and perceived tailbone relief, while also describing mixed firmness and stability experiences. Some report that the cushion feels too firm or slides on their chair despite the listed non-slip base. In practice, fit and feel may depend on the seat and the buyer’s preference, so the dimensions and reported firmness differences matter. Aggregate ratings are generally favourable but do not establish how it will feel on a particular chair.
- Positive themes: Customers report comfort, support and cushioning, and some describe relief from tailbone discomfort.
- Positive themes: Some customers consider the cushion worth the money.
- Negative themes: Some customers report that it slides off their chairs.
- Mixed feedback: Firmness feedback varies, with some finding it too firm.
- Mixed feedback: Stability feedback varies despite the listed non-slip base.

## Frequently asked questions

No. The care instructions say the foam core is not washable. The cover can be machine-washed in cold water and should be air-dried. Do not bleach, tumble dry or iron it.
### How firm is the cushion?
The details field calls it medium, while the feature text describes a medium-firm feel. Customer feedback also reports mixed opinions, including that some find it too firm.
