Onyx 7,750

The Onyx 7,750 from the Harrison Spinks Optimum Support collection of mattresses is made with Cortec™ Quad recyclable pocket springs, layered with HD 2500 Micro Springs and Posturfil pocket springs that adapt to your body’s contours to relieve pressure and provide greater comfort and lumbar support.

This is a seasonal turn mattress with a warm side featuring a wool blend to keep you warm during the colder months, and a cool side featuring a moisture-wicking cotton blend close to the sleeping surface, keeping you fresh and dry during the warmer months.

All 7,750 pocket springs within the mattress are recyclable, along with all-natural sustainable fillings including British wool, Egyptian cotton, kapok, lustrous alpaca, home-grown firming needled hemp and sumptuous mohair.

The ultimate in comfort

It genuinely has transformed our sleep and I would not hesitate to recommend a Harrison Spinks bed to anyone.


Lovely bed

Lovely bed, so comfortable and having the two zones one medium and one hard just works for us.


Elba mattress & divan base

I bought a HS Elba mattress & divan base from Belgica Furniture in early November. I wake each morning feeling refreshed after a thoroughly comfortable sleep.
