Undersized Mattresses

An undersized mattress is any size smaller than standard UK dimensions. This includes narrow singles under 90cm wide, short doubles under 190cm long, or any custom rectangular size. Common examples are caravan fixed beds, boat berths, children's cabin beds, and antique bed frames with non-standard measurements.

Measure the internal dimensions of your bed base in centimetres. Take length, width, and note any height restrictions. Measure twice to ensure accuracy. If the space has rounded corners or unusual shapes, note these details. Most undersized mattresses need measurements accurate to within 1cm for a proper fit.

Undersized mattresses come in memory foam, pocket springs, reflex foam, and natural latex. Memory foam works well in tight spaces as it compresses easily during installation. Pocket springs offer traditional support but need adequate height clearance. All materials meet BS 7177 fire safety standards required for caravans and motorhomes.

Lead times typically range from 7-14 working days depending on seasonal demand and current production capacity. Each mattress is made to order, so cannot be dispatched immediately. Rush orders may be possible during quieter periods. Free UK delivery is included, with the mattress vacuum-packed for easier handling in tight spaces.

Yes, undersized mattresses can be cut with rounded corners to fit island beds or unusual shapes. Provide a template or detailed measurements showing the curve radius. This customisation doesn't affect the price but may add 1-2 days to production time. Most caravan and boat beds benefit from this option.

Thickness depends on your space and comfort needs. 10-15cm works for occasional use, while 18-20cm provides better comfort for regular sleeping. Check headroom clearance and any storage compartments underneath. Thinner mattresses are easier to install through narrow doorways but may compromise long-term comfort and support.

Yes, guarantees up to 10 years are available depending on the materials chosen. Memory foam typically carries 5-10 year guarantees, while pocket springs offer 8-10 years. The guarantee covers manufacturing defects and premature sagging. Custom sizes don't affect guarantee terms, and all mattresses undergo quality checks before dispatch.
