What the Sleep Expert thinks...

"The Tonedale really does represent what Relyon is all about. I'd recommend it to anyone looking for indulgent comfort and a deep mattress that you can climb up onto in the evening."

Description

In tribute to the rich textile legacy of the village of Tonedale, the Relyon Tonedale 4500 Natural Heritage Mattress celebrates a proud connection between British wool and West Country craftsmanship. Handcrafted here in the UK, this mattress embodies the prestigious reputation of comfort and support that Relyon has earned since it first began manufacturing in 1858.

Thousands of individual pocket springs provide unparalleled support

Up to an incredible 4,500 individually pocketed springs provide the truly impressive level of support you'll experience from this mattress. Each spring, housed in its own fabric pocket, quickly and effectively adapts to your every move, applying gentle pressure relief exactly where you need it. With a balanced medium feel, these springs help to keep you in the healthiest sleeping posture, promoting spinal alignment in any sleeping position.

Sink into a deep pillow top plumped with sustainable British wool

A plump pillow top of sustainably sourced British wool is what really sets this mattress apart. As soon as you climb into bed, you'll be greeted with soft, sumptuous layers of natural materials that let your body sink just the right amount into your mattress. Highly breathable for a refreshing sleep, wool is also known for its elasticity, giving you extra bounce for extra comfort.

Stretch out on one of the most luxurious mattresses on the market

Relyon's specialist Edge+ system reinforces the mattress edges, giving you a larger usable sleep surface so you can stretch out and get comfortable. You'll also notice less side-sagging, and won't have to worry about the dreaded 'roll off'. At a grand 37cm depth, the Relyon Tonedale 4500 Natural Heritage Mattress will sit in pride of place on your bed frame, making it the perfect centrepiece for your master bedroom, or something to treat your friends and family to in your guest room.

Features

4500 Pocket Springs

Pocket springs are springs mounted in their own separate fabric pockets, meaning they work completely independently of one another and can provide your body with better pressure relieving support.

Sustainably Sourced British Wool

Sustainable British wool provides gentle cushioning with impressive resilience, offering durable, indulgent comfort.

37cm Depth

This mattress is approximately 37cm deep.

Belgian Damask Viscose Sleep Surface

A silky soft, highly breathable cover that helps to create a fresher sleeping environment.

Air Vents

Vents which allow air to flow in and out of the mattress are mounted on the sides. These vents help to keep the air within fresh and cool.

No Need To Turn

A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.

Pillow Top

Pillow top mattresses have the benefit of an additional pillow layer of plush fillings on the top of the mattress, which provides extra luxurious comfort.

No Roll Together

Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.

Hypoallergenic

Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.

Hand Tufted

Tufts help to secure the luxury fillings in place, helping the mattress retain it's fullness and plumpness over time.

Edge+™ Side Support

Reinforced edges maximise the usable sleep surface, giving you more room to relax and consistent support right to the very edge.

Fire Resistant - Low Hazard

This product conforms to the BS7177: 2008 standard for domestic use (low hazard) - ideal for use at home.

Handmade in Somerset

Expertly handcrafted in Somerset by local craftspeople, this mattress reflects generations of British mattress-making tradition and quality.
