Assessed from Sleepeezee's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose this if you want natural fillings and a softer feel without giving up spring support. The two-tier spring system, mini comfort springs over traditional pocketed springs, means the surface contours to your shape while the base layer handles deeper support, and Caliber edge side support helps you use the full width of the bed. The wool credentials are genuine rather than a marketing flourish: 100% British Wool with Platinum Wool label accreditation, plus a Royal Appointment to His Royal Highness The Prince of Wales. Wool also regulates temperature naturally, a quiet advantage if you tend to overheat. £699 to £1,249 is a real spend, but the depth, spring count and natural materials justify the position.
Key Features & what's inside
- Pillow top finish. A sumptuous pillow top with a Damask cover and deep woollen tufting. The tufting keeps the fillings anchored in place, so the surface stays even over time.
- British wool & mohair comfort layer. British wool blended with mohair sits directly beneath the surface, which means a soft, breathable first point of contact. Both fibres help regulate temperature through the night.
- British wool layer. A further layer of British wool adds cushioning depth. It builds on the natural, gently yielding feel of the layer above.
- High density support layer. A high density layer that firms up the transition between the soft fillings and the springs below. You sink into comfort rather than through it.
- Mini comfort springs. 2,500 mini comfort springs respond to smaller shifts in pressure, which means closer contouring around shoulders and hips. They add responsiveness that foam alone can't match.
- High density support layer. A second high density layer separates the two spring systems. It keeps each tier working independently.
- Pocketed springs. 1,200 traditional pocketed springs form the main support base, each moving on its own to follow your shape and limit motion transfer. Caliber edge side support firms the perimeter, so you can sleep right to the edge.

Who's it NOT for?
This is a Medium-Soft mattress, so it's unlikely to suit anyone who needs a firm surface, including heavier sleepers and most dedicated front sleepers, who may find their hips dip too far. The pillow top is fixed rather than a flippable design, and if you prefer the closer hug of memory foam, the springy wool feel here is quite different.
