Before ordering

A named size is not a fit guarantee. Compare the seller’s finished width, length and stated tolerance with the frame opening and bedding specification.

Published tolerance: Nominal UK convention; verify the finished product.

Measure the finished mattress and the frame’s internal opening. Measure the mattress correctly and check which frame dimension controls fit.
