Sleepeezee describes the Campaign for Wool Luxe 3700 as Medium-Soft, which means a gentler, more cushioned surface than a standard medium, so side sleepers and lighter bodies should feel the benefit most. Inside are 3,700 springs in total: 2,500 mini comfort springs paired with 1,200 traditional pocketed springs, topped with British wool and mohair beneath a tufted pillow top. At 29cm deep, it has a properly plush, hotel-style build. It comes in five UK sizes, from Single to Super King, and Sleepeezee backs it with a 10-year guarantee.

Why should you choose this mattress?
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. It's a real spend, but the depth, spring count and natural materials justify the position.
Key features & layer details
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.

Best suited for?
Side sleepers
The Medium-Soft feel and 2,500 mini comfort springs contour closely around shoulders and hips, which means pressure points get a cushioned surface to settle into.
Lighter sleepers
A softer, more cushioned surface means lighter bodies sink into the wool and mohair layers properly, so the plush comfort is felt more than on a firmer mattress.
Warm sleepers
British wool and mohair in the comfort layers both help regulate temperature through the night, which suits anyone who tends to overheat in bed.
Couples
Individually moving pocketed springs limit motion transfer, while the Caliber edge support firms the perimeter so both people can use the full width of the bed.
Eco-conscious buyers
Natural fillings run throughout, including 100% British Wool with Platinum Wool label accreditation and mohair, so the comfort layers come from natural fibres rather than foam.
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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.
