Harrison Spinks Radiant Pillowtop 15000 im Test

The Harrison Spinks Radiant Pillowtop 15000 is a turn-free mattress with an attached pillow top, built on 15,000 springs and natural fillings. Harrison Spinks describes its pillow tops as a layer you sleep in rather than on, and the Radiant is the most widely stocked of its four pillow top models. A double costs £2,059 at Now to Bed (October 2026).

Construction

The spring unit stacks three grades of micro springs, HD 2,000, HD 3,000 and HD 4,000, over Cortec Quad Revolution and Posturfil pocket springs, which is more spring layers than any turn-free Harrison Spinks model on our list. British wool blends, a cotton, hemp and flax blend and a cover woven in-house without FR chemical treatment complete it, finished with three rows of side stitching.

Who it suits

We rate the feel medium-soft, 4 out of 10: the pillow top cushions shoulders and hips while the deep spring unit keeps the spine supported. That makes it a strong choice for side sleepers and for couples who want a plush bed that never has to be flipped. Front sleepers will find it too soft. The appeal over a seasonal turn mattress is practical, because a pillow top is one-sided, and that is also its weakness: every night falls on the same surface, so the fillings settle where you lie.

Prices and care

A single costs £1,499 and a super king £2,859 at Now to Bed, with delivery in four to seven weeks. In a double that is a little more than the Emerald 16500, which has more springs but must be turned twice a year. The Harrison Spinks care guide asks owners of pillow top mattresses to rotate them weekly for the first 12 weeks and monthly after that, and it treats body impressions in natural fillings as normal, so plan for that routine before you buy.
