- The listing uses both medium and medium-firm descriptions for feel, gives dimensions as both 35.6L x 45.7W x 7.6H centimetres and 46x36x7.5 cm, and lists semicircular shape alongside a U-shaped design. Confirm the selected listing's dimensions and profile. Its stated recommendation is for users around 70-100 kg, and it advises measuring the chair before purchase. Customer feedback also includes mixed reports of firmness and chair stability.

## A good fit for

## Customer feedback

Customer feedback describes comfortable padding, support and perceived relief from tailbone discomfort, with some also considering it worthwhile for the money. However, firmness and stability are mixed: some find it too firm, and some report that it slips despite the listed non-slip base. These differences matter if you need a particular feel or a cushion that stays put on your chair. Aggregate ratings are broadly positive, but they do not establish a uniform experience.
- Positive themes: Customers report comfortable, well-padded cushioning and support.
- Positive themes: Customer feedback includes reports of tailbone discomfort relief and good value.
- Negative themes: Some customers report that the cushion slides off their chairs despite the listed non-slip base.
- Mixed feedback: Firmness receives mixed feedback, with some finding the cushion too firm.

## Frequently asked questions

### Can the whole cushion be machine washed?
No. The care details say the foam core is not washable. The cover is machine washable in cold water and should be air dried. Do not bleach, tumble dry or iron.
### Will it fit my chair?
The listing describes it for standard and compact chairs and gives dimensions, but also presents slightly different measurements elsewhere. Measure your seat and confirm the dimensions and shape for the selected listing.
### Is the cushion firm or medium?
The details list medium firmness, while feature copy describes a medium-firm feel. Customer feedback is mixed, with some finding it too firm, so the exact feel may not suit everyone.
