Assessed from Feather & Black's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The Elsham suits you if you want natural materials without a top-end price. The Black Country wool is fully traceable and helps regulate temperature, which means less of that clammy feeling if you run warm at night. The pocket springs respond to each sleeper independently, so a restless partner is less likely to wake you. It is also double-sided, rarer these days, meaning regular flipping should extend its useful life. The medium tension should suit most sleepers, although those who prefer a very firm or very soft feel may want to look elsewhere. The 1 year guarantee is shorter than many brands offer, which is the main compromise at this price.
Key Features & what's inside
- Cover. A sumptuously soft natural cover, designed for enhanced breathability. In practice, that means air can move through the sleep surface rather than trapping heat against you.
- Wool. Fully traceable Black Country wool that regulates temperature. Wool wicks moisture and buffers heat, so you should feel more even in temperature through the night.
- Fibres. Recyclable, air-blown fibres that give the feel of a million micro springs. This creates a cushioned, responsive surface layer above the main spring unit.
- Pocket Springs. Individually encased pocket springs that adapt to your body's movements to minimise disturbance to your partner, while supporting your back and hips. Each spring moves on its own, so one person turning over is less likely to jolt the other.

Who's it NOT for?
Skip the Elsham if you need a long warranty for peace of mind: the guarantee is 1 year. The 100 Night Comfort Guarantee applies only in-store with a mattress protector, so online-only buyers lose that safety net. Fans of a very firm feel may find this medium tension a little forgiving.

How firm is the Feather & Black Elsham mattress?
Feather & Black describes the Elsham as a medium tension mattress. That middle-ground feel suits most sleeping positions, although committed stomach sleepers who like a firmer surface, or lightweight side sleepers wanting something softer, may prefer a different tension.
Does the Feather & Black Elsham have a sleep trial?
There is a 100 Night Comfort Guarantee, but with conditions: it is valid only in-store, and you must use a mattress protector. If you plan to buy online, check with Feather & Black how, or whether, the guarantee applies to your order before committing.
How many springs does the Elsham mattress have?
Spring count varies by size. The double is listed with 858 individually wrapped pocket springs, while Feather & Black's page references 1,000 individually wrapped pocket springs for the king size. Larger sizes generally carry more springs to cover the wider surface.
Can you flip the Feather & Black Elsham mattress?
Yes, the Elsham is double-sided, so you can flip it as well as rotate it. Turning a mattress regularly helps the fillings settle evenly, which tends to keep the feel consistent for longer than a one-sided design.
What is delivery like for the Feather & Black Elsham?
Feather & Black offers free delivery on all orders, with two man delivery to your room of choice. Anticipated delivery is within 14 days after the product arrives at the delivery depot, so allow a little flexibility on timing.
