What size is a double mattress?

A standard UK double mattress measures 4ft 6in x 6ft 3in (135cm x 190cm) and is designed to fit most double bed frames.

Who is a firm double mattress suitable for?

Firm double mattresses are often chosen by sleepers who prefer a more structured sleep surface with minimal sink-in. They can be particularly appealing to back sleepers and those who enjoy a steadier feel across the mattress.

What types of firm double mattresses are available?

Our options include memory foam, pocket sprung, hybrid, and orthopaedic mattresses. Each offers a slightly different feel while maintaining a firmer level of support.

Memory foam mattresses gently contour to the body while pocket sprung designs provide responsive support through individual springs. Hybrid mattresses combine multiple comfort technologies in a single design. Orthopaedic mattresses are designed to offer a firmer, more structured sleeping surface with a focus on support.
