Assessed from Feather & Black's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose the Boulton if you want a traditional, deep-filled feel with natural materials rather than foam. The silk and mohair blend is soft to the touch and regulates temperature, which means less overheating on warm nights, while the Platinum 3D polyester layer is fully recyclable at the end of its life. Yes, it is a considerable spend at £1,199 upwards, but the 10,000-spring count and 30cm depth go some way to justifying the price. Free two-man delivery to your room of choice takes some of the hassle out of the purchase, and the 100-night trial gives you a proper chance to sleep on it before committing.
Key Features & what's inside
- Pillow top. A luxuriously plump pillow top sits on the surface, which means a softer, more cushioned first feel before you reach the supportive layers beneath.
- Damask fabric. The mattress is wrapped in soft-touch damask fabric. It gives the sleeping surface a smooth, gentle finish against bedding.
- Silk and mohair blend. A silk and mohair blend brings sumptuous softness and helps regulate temperature. In practice that means the mattress should feel less clammy if you run warm at night.
- Platinum 3D polyester. This Platinum 3D polyester layer is fully recyclable at the end of its life, a small but genuine environmental plus for a mattress in this bracket.
- Pocket springs. Individually wrapped pocket springs distribute body weight evenly for head-to-toe support. Because each spring moves independently, you should feel less disturbance when a partner shifts position.

Who's it NOT for?
If you prefer the contouring hug of memory foam, the springy pillow-top feel here will not suit you. The 1-year guarantee is short for a mattress at this price, so if long cover matters to you, look elsewhere. The 30cm depth may also mean your existing fitted sheets no longer fit.
Feather & Black Boulton Mattress
How firm is the Feather & Black Boulton mattress?
Feather & Black describes it as a medium-firm tension with adaptive support, suitable for side, front and back sleepers. The plump pillow top softens the initial feel, so it sleeps a little gentler on the surface than the tension alone suggests.
How many springs does the Boulton mattress have?
It contains 10,000 individually wrapped pocket springs. Each spring responds separately to pressure, which means your weight is distributed evenly and movement on one side of the bed transfers less to the other.
Does the Feather & Black Boulton come with a trial?
Yes, Feather & Black offers a 100-night trial, so you can sleep on it at home for over three months before deciding. It also comes with a 1-year guarantee, which is on the short side for this price bracket.
What sizes does the Boulton mattress come in?
It is available in UK Single, Small Double, Double, King and Super King. Prices range from £1,199 to £2,099 depending on the size you choose.
Is delivery free on the Feather & Black Boulton?
Yes, Feather & Black offers free delivery on all orders, including two-man delivery to your room of choice. Anticipated delivery is no more than 14 days after the product reaches the delivery depot.
