What to know before buying
Listing details to confirm
The listing is inconsistent about construction and measurements: the title and feature bullets describe an L-shaped cushion measuring 46 × 42 × 40 cm, while the description calls it a U-shaped donut and gives differing surface dimensions. Weight is listed as 1.15 Kilograms in the specifications but 0.6–0.8kg in the description. The cover is described as breathable mesh in the features and velvet in the description. Confirm the selected listing's actual shape, measurements, weight and cover before purchase. Claims about pain relief, spinal alignment, pressure reduction and long-term support are not independently established here.

Frequently asked questions
Does the cushion have a separate lumbar pillow?
The feature listing describes a one-piece L-shaped design with lumbar support rising from the seat, rather than a separate pillow.
Can the cover be washed?
The feature listing says the cover is removable and machine washable. The description conflicts on whether the cover is mesh or velvet, so confirm the material for the selected listing.
Will it fit my chair or car seat?
The listed dimensions are 46L x 42W x 40H centimetres, and suggested uses include office chairs, car seats and wheelchairs. Check the available seat area and the listing's conflicting shape and measurement details before buying.
Does it treat tailbone or back pain?
The listing makes pressure-relief and pain-relief claims, but these are not established as medical outcomes by the supplied information.
