About Extra Deep Mattresses

Extra deep mattresses typically measure 25cm or more in depth, significantly thicker than standard mattresses which usually range from 15-20cm. These mattresses suit people who prefer more cushioning, need additional support for joint problems, or want a more luxurious sleeping experience. Standard bed frames and sheets often don't accommodate the extra depth properly. Made-to-measure extra deep mattresses solve fitting issues by being cut to your exact bed dimensions whilst maintaining the deeper profile you need for comfort.

Extra Deep Mattress FAQs

Extra deep mattresses start at 25cm depth and can go up to 35cm or more. Standard mattresses typically measure 15-20cm deep. The extra depth comes from additional comfort layers like memory foam, latex, or extra pocket springs. Depths of 28-30cm are most popular as they provide substantial comfort without being too bulky for most bed frames and bedding.
Standard fitted sheets won't fit properly on extra deep mattresses. The elastic won't stretch enough to cover the depth, causing the sheet to pop off. Deep fitted sheets with pockets of 32cm or more work best. Some manufacturers make super deep fitted sheets specifically for mattresses over 30cm thick. Always check the pocket depth when buying bedding.
Most standard bed frames can support extra deep mattresses, but check the weight capacity. The extra materials make these mattresses heavier than standard ones. Platform beds work well as they provide full support. Slatted bases need slats no more than 7cm apart. Some adjustable bases may struggle with the extra weight and thickness.
Made-to-measure extra deep mattresses typically take 7-14 working days to manufacture and deliver. Lead times vary depending on seasonal demand and current production capacity. Complex constructions with multiple foam layers may take slightly longer. Free UK delivery is standard. The mattress arrives compressed and rolled for easier handling through doorways.
Memory foam, latex, and pocket springs all work well in extra deep constructions. Memory foam provides excellent pressure relief in thicker layers. Natural latex offers good support and breathability. Pocket spring systems with multiple comfort layers combine support with cushioning. All materials must meet BS 7177 fire safety standards for insurance compliance.
Extra deep mattresses can work on adjustable beds but check the maximum thickness your base can accommodate. The extra depth may limit the range of adjustment angles. Flexible materials like memory foam and latex bend better than thick spring systems. Some adjustable bases have weight limits that thicker mattresses might exceed. Always verify compatibility before ordering.
Quality extra deep mattresses typically come with guarantees ranging from 5-10 years depending on the materials and construction. Memory foam and latex versions often have longer guarantees than spring mattresses. The guarantee covers manufacturing defects and premature sagging. Custom-made mattresses have the same guarantee terms as standard sizes from reputable manufacturers.
