Description

Drift off to dreamland with the gorgeously plush Harrison Spinks Grassington 5750 Pocket Mattress.

Featuring generous layers of natural fillings and thousands of pocket springs, this medium-firm mattress will feel tailor-made, just for you. It's exclusive to us at Mattress Online.

Smooth and decadent

Handcrafted from a fine blend of 100% Yorkshire wool and wrapped in a soft-touch cover, the Grassington will envelop you in comfort.

Perfect temperature, year-round

A natural insulator, wool gently regulates your body temperature during the changing seasons. You'll feel cooler in summer and warmer in winter.

Thanks to the cooling layers of cotton, flax and hemp, this mattress will help if you overheat in the night. These clever fibres are breathable, for a fresher feel.

Medium-firm feel

This is the perfect mattress if you need a little extra support. We rate it medium-firm - so it's ideal if you prefer a slightly firmer, more supportive feel.

Looking for a firmer mattress? The Harrison Spinks Knaresborough features orthopaedic support and and a truly firm feel.

Total body support

Harrison Spinks' Cortecâ„¢ Quad Core spring system is at the heart of the Grassington. Every spring is encased in a breathable pocket, providing extra airflow around your mattress.

Featuring an impressive 5750 pocket springs, you'll enjoy perfect support for every area of your body. Each spring reacts to your unique shape, for greater comfort and pressure relief. This spring count includes not only traditional pocket springs but also mini springs. Mini springs offer extra comfort within the spring system for a blissful rest.

The perfectly-supportive pocket springs help reduce motion transfer and roll-together. That means you and your partner can experience a deeper, more peaceful sleep.

Better for you and our planet

Harrison Spinks operate with a great deal of love and care for our planet and their customers. This is why they make all their mattresses right here in the UK to reduce their carbon footprint. Their luxury hemp and flax fibres are all grown on their farm which also houses their impressive collection of award winning sheep. They use sustainable 100% British wool in their mattresses to offer indulgent softness and comfort.

Years of comfort

This is a mattress that will stand the test of time. Thanks to expert hand tufting and 2 rows of side-stitching, all the sumptuous fillings are carefully locked in.

Conveniently designed

The Grassington is designed for easier care. Since it's single-sided, you'll never need to turn it over.

With 4 built-in turning handles, it's easy to rotate. We recommend doing this once every 6 months, to keep it in the great condition you expect.

Sleep deeper, wake refreshed

Enjoy well-deserved rest and relaxation with the natural comfort and handcrafted goodness of the Grassington. Ready for you tomorrow, deeper sleep is only a day away!
