Firmness: Medium · 200-night sleep trialThe Naturalmat Terrific is a 6cm handmade topper of natural latex wrapped in organic wool, adding springy comfort to a tired mattress.
The Naturalmat Terrific is a 6cm topper with a natural latex core wrapped in organic wool and an organic cotton and wool cover, handmade to order in Devon. It sits in the middle of Naturalmat's topper range, adds both cushioning and some support to a tired mattress, and at the time of writing (September 2026) it costs £630 in a single and £760 in a Naturalmat double (137 x 190cm).
The Terrific product page lists three materials, sewn, tape-edged and tufted by hand like a mattress.
| Layer | Material | What it does |
|---|---|---|
| Core | Natural latex from Hevea rubber-tree sap, aerated | Springy support in place of synthetic foam |
| Wrap | Organic wool from local farms | Softens the surface, manages heat and moisture |
| Cover | Organic cotton and wool blend | Meets UK fire rules without chemical retardants |
Naturalmat describes the Terrific as "not too soft, not too firm", and it publishes no firmness grade, so our medium 5/10 rating is an estimate from the build. Latex pushes back quickly, which keeps you on top of the topper rather than in it, while the wool takes the edge off the surface. That balance suits back and side sleepers on a mattress that has become uncomfortable but is still flat. One buyer reviewing it on Naturalmat's site found it firmer than expected on an already firm mattress, so do not count on it to soften a very hard bed.
A topper only helps if the mattress under it is sound. The National Bed Federation's guide to whether you need a new bed lists sagging, lumps and an age of more than seven to 10 years as signs that the mattress itself needs replacing, and a 6cm topper will follow any dip beneath it.
| Naturalmat topper | Depth | Fillings | Our firmness rating | UK double (137 x 190cm) |
|---|---|---|---|---|
| Frome | 2.5cm | Two layers of organic wool | Medium-soft, 3/10 | £420 |
| Terrific | 6cm | Natural latex core, organic wool | Medium, 5/10 | £760 |
| Tremendous | 7cm | Natural latex core, cashmere and organic wool | Medium, 4/10 | £880 |
Firmness figures are our assessment from the materials; Naturalmat does not grade toppers. The Tremendous adds cashmere and a centimetre of depth for about £120 more in a double.

The Naturalmat guarantee covers adult toppers for 2 years against 10 years for its mattresses, and toppers are excluded from the 45-day Sleep Promise; the standard returns policy allows 14 days, with return postage paid by you unless the topper is faulty. Naturalmat asks for toppers to be turned every three months to even out the wear on natural fibres.

“The Terrific is the most balanced Naturalmat topper: 6cm of latex and wool adds cushioning and support at once and keeps a foam mattress breathable. It is not the choice for a very hard bed or a tight budget, and the guarantee is only 2 years.”Go to shop →
