About Firm Mattresses

Firm mattresses provide enhanced support with minimal surface give, ideal for those who prefer sleeping on a harder surface or need extra spinal alignment. Standard shop-bought mattresses rarely fit motorhomes, caravans, or boats properly due to their unusual shapes and sizes. Custom-made firm mattresses solve this problem by being cut to your exact measurements, ensuring a perfect fit in corner beds, island beds, or any awkwardly shaped sleeping area. Made-to-measure options include various firmness levels within the firm category, from medium-firm to extra-firm, using high-density foams and supportive spring systems.

Firm Mattress FAQs

Firm mattresses use denser foam layers and stronger spring systems that compress less under body weight. This creates a sleeping surface with minimal sinkage, providing enhanced support for the spine and joints. The reduced contouring means less pressure point relief compared to softer options, but better overall body alignment for those who prefer sleeping on top of rather than sinking into their mattress.
Yes, firm mattresses can be manufactured to any size and shape required. This includes corner beds, island beds, V-berths, and other irregular shapes common in motorhomes and boats. Measurements are taken to the nearest centimetre, ensuring the mattress fits perfectly within the available space without gaps or overhang that could affect comfort or safety.
Lead times typically range from 7-14 working days depending on seasonal demand and current production capacity. Custom firm mattresses require manufacturing time as each one is made to order rather than held in stock. Free UK delivery is included, with the mattress arriving compressed and rolled for easy transport through narrow doorways and tight spaces.
Firm mattresses can work for couples, though they provide the same level of support across the entire surface. If partners have significantly different comfort needs, consider a split-tension option where each side has different firmness levels, or separate mattresses for each sleeping area. The reduced motion transfer in firm mattresses can actually benefit couples as movement is less likely to disturb a sleeping partner.
Firm mattresses typically come with guarantees up to 10 years, covering manufacturing defects and premature sagging. The guarantee terms depend on the specific materials and construction method used. All mattresses include BS 7177 fire safety certification, which is required for motorhome and caravan insurance compliance, ensuring peace of mind for mobile accommodation use.
Firm mattresses work well on most existing bed bases, including slatted frames, solid platforms, or adjustable bases. The key requirement is adequate support - slats should be no more than 7cm apart to prevent sagging between gaps. Solid bases provide excellent support for firm mattresses, while very soft or damaged bases may compromise the intended firmness level.
Yes, firm mattresses can incorporate natural materials like organic cotton covers, natural latex layers, or coconut coir for firmness. These materials provide the same supportive qualities as synthetic options while offering benefits like temperature regulation and reduced chemical exposure. Natural firm mattresses may have slightly longer lead times due to material sourcing requirements.
