Mattress Size & Firmness


Mattress Size & Firmness

When selecting your Glencraft Mattress, it's important to ensure you choose the correct level of Firmness. Firmness is determined by a combination of pocket spring tension, density and the layers of natural fabrics.

Most commonly, a medium firmness will provide the perfect balance of support and comfort. The ideal firmness depends on how the mattress is made, sleeping position, body shape and ambient temperature.

Please note, if the internal measurements of any bed frame differ from the standard sizes listed, Glencraft can't be held responsible in the event of the mattress not fitting.

Due to our mattresses being bespoke and hand-finished, no two mattresses are identical and come with a variance tolerance of 1 inch.
