Extra Firm Mattresses

Extra firm mattresses use higher density materials and thinner comfort layers. They typically rate 8-10 on firmness scales compared to 6-7 for firm mattresses. The support core contains denser foam or more tightly packed springs. Comfort layers are minimal, usually just a thin quilted cover. This creates a very hard sleeping surface with little give when pressure is applied.

Yes, extra firm mattresses can be made to any dimensions. Measurements are taken to the nearest centimetre for width, length and thickness. Common applications include narrow caravan beds, curved motorhome layouts, and antique bed frames with unusual proportions. The mattress is cut from larger blocks of high-density material to match exact specifications.

Most extra firm mattresses work well at 15-20cm thick. Thinner versions around 10-12cm suit weight restrictions in caravans or low-profile bed bases. Thicker options up to 25cm provide additional durability for heavier users. The firmness comes from material density rather than thickness, so even thinner versions maintain their supportive properties.

All extra firm mattresses include BS 7177 fire safety certification as standard. This certification is required for caravan and motorhome insurance policies. The materials and construction meet strict flammability standards. Certification documents are provided with each mattress for insurance purposes. The same safety standards apply regardless of custom dimensions.

Lead times typically range from 7-14 working days depending on seasonal demand and current production capacity. Each mattress is made to order after measurements are confirmed. Free UK delivery is included in the price. Mattresses are vacuum-packed for easier handling and delivered by courier. Peak holiday seasons may extend delivery times slightly.

Extra firm mattresses work well for couples who both prefer very hard sleeping surfaces. Motion transfer is minimal due to the dense materials. However, if partners have different firmness preferences, the lack of cushioning may be uncomfortable for one person. Consider individual comfort needs before choosing extra firm options for shared beds.

Guarantees up to 10 years are available depending on the specific materials and construction used. The guarantee covers manufacturing defects and premature sagging beyond normal wear. High-density foams and quality spring systems maintain their firmness longer than standard materials. Guarantee terms are provided with each mattress along with care instructions.
