What to know before buying
Listing details to confirm
Water protection is unclear: the title and feature text describe water-repellent fabric and a water-repellent base, while the details list “Not Water Resistant” and “Water Resistant”. Dimensions also conflict: the details say 36L x 36W centimetres, while the feature listing gives H50 x W36 x D27 cm. Confirm the selected listing's dimensions and included wet-clothing bag before buying. These are listing inconsistencies, not proof of a product defect.
