King size mattresses measure 150cm x 200cm (5ft x 6ft 6in) as standard. However, many bed frames, particularly in caravans, motorhomes, and boats, have slightly different dimensions. A standard high street king size mattress often leaves gaps or won't fit at all. Made-to-measure king size mattresses solve this problem by cutting foam to your exact measurements. This ensures a perfect fit for unusual bed bases, fixed furniture, or spaces with specific width and length requirements. Custom cutting also allows for corner cuts, curves, and thickness variations that standard retail mattresses cannot accommodate.

King Size Mattress FAQs
Standard king size mattresses measure 150cm wide by 200cm long (5ft x 6ft 6in). However, many bed frames vary from these dimensions. Made-to-measure options can be cut to any size within the king size range, ensuring a perfect fit for your specific bed base or space requirements.
King size mattress thickness typically ranges from 10cm to 25cm. The right thickness depends on your bed frame height, comfort preference, and any storage underneath. Thicker mattresses generally offer more support and comfort, whilst thinner options work better for low-profile beds or weight restrictions.
Yes, custom king size mattresses can include corner cuts for fixed furniture, curved edges for boat berths, or notches for bed frame posts. Standard retail mattresses cannot accommodate these modifications. Made-to-measure cutting allows for any shape whilst maintaining the overall king size proportions.
Lead times for custom king size mattresses typically range from 7-14 working days, depending on seasonal demand and current production capacity. Standard sizes may be available sooner, whilst complex shapes or specialist foams may take longer. Free UK delivery is included as standard.
All king size mattresses include BS 7177 fire safety certification, which is required for motorhome and caravan insurance. This certification ensures the foam meets UK safety standards for domestic and leisure vehicle use. Certificates are provided with each mattress for insurance purposes.
King size mattresses are available in reflex foam, memory foam, and high-density support foam. Reflex foam offers good support and bounce-back. Memory foam moulds to body shape for pressure relief. High-density foam provides firm, long-lasting support. All foams can be cut to custom dimensions.
Custom king size mattresses come with guarantees up to 10 years, depending on the foam type selected. This covers manufacturing defects and premature foam degradation under normal use. The guarantee applies to both standard and made-to-measure sizes, ensuring long-term peace of mind.
