## Before you buy

- Size and thickness details conflict: the title calls this Super King and 10cm thick, while the size field states 5ft King - 150x200cm and the displayed dimensions are 2 x 1.5 x 0.1 metres. Confirm the intended mattress size and actual dimensions before ordering. The listing also describes non-slip dots but customer feedback is mixed on whether it stays in place, and firmness impressions vary. Certification claims are stated in promotional copy, not verified here.
