British Bed Company The Ortho King Mattress

Assessed from British Bed Company's published specification for this mattress, captured October 2026, and from regular price comparison across our UK retail partners.

The firm feel suits sleepers who want a flat, supportive surface rather than a sinking one, which usually means back and front sleepers. The fillings are 100% hypoallergenic polyester fibre, a sensible point if you're sensitive to allergens. The mattress is two sided, so you can turn it to spread wear and help it last longer. It's also hand-tufted, handled and vented. At 28cm deep, it's a fair height on most bed frames. Mid-range in price, it's a straightforward, traditional choice, although side sleepers may find it too firm.

Back sleepers
The firm feel gives a flat, supportive surface rather than a sinking one, which suits anyone who likes to lie on their back.

Front sleepers
Firm support keeps the surface flat beneath you rather than letting you sink in, which is what many front sleepers look for.

Allergy sufferers
The fillings are 100% hypoallergenic polyester fibre, which makes it a sensible pick if you are sensitive to allergens.

If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It's rated firm, and the fibre fillings are there for support rather than deep cushioning. Side sleepers and lighter sleepers may find it hard on their shoulders and hips. British Bed Company also doesn't publish a spring count.

How firm is the British Bed Company The Ortho King?

It's rated firm. That suits back and front sleepers who want a flat, supportive feel, but side sleepers and lighter sleepers may find it too unyielding at the shoulders and hips.
