Description

The culmination of 100 years of Sleepeezee's masterful mattress design, the Sleepeezee Centurial 01 4500 Pocket Natural Mattress is not only a truly indulgent natural mattress, but offers unparalleled support for the most rejuvenating sleep possible.

Orthopaedic support to your entire body

Blending innovative, modern technology with tried and tested traditional techniques, this mattress hosts thousands of ingenious pocket springs as well as layers of breathable, natural fibres. These reactive pocket springs adapt to your movements in the night, tailoring support to your pressure points as your weight is dispersed. With orthopaedic support, you'll find your spine is kept properly aligned for the prevention of aches and pains.

Natural alpaca fleece and breathable wool

Sumptuous layers of natural alpaca fleece and insulating wool not only offer a plush surface for your body to rest upon, but offer temperature regulating properties that keep you cool, fresh and dry. A soft damask cover finished the Centurial 01 Mattress in true style, allowing maximum airflow for the most hygienic sleeping environment possible.

Reinforced edges ensure you enjoy the full surface of this exquisite mattress, while no roll together technology offers personalised sleeping zones for you and your partner, preventing you from rolling towards the middle. Hand tufting keeps all fillings in place, while also representing the high quality nature of this regal mattress.

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.

Wool

This type of filling gives a soft cushioned feel to the mattress. Wool is ideal for those who prefer their mattress to be traditional and natural.

Alpaca Fleece

Alpaca Fleece is a high-quality natural filling. An Alpacas fleece is known for being soft, durable and luxurious, it is also a warmer alternative to sheep’s wool.

26cm Depth

This mattress is approximately 26cm deep.

Damask Cover

A mattress cover which is made from a breathable Belgian damask fabric.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

Reinforced Edges

The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.

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.

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 Side Stitched

This mattress has been hand stitched on the borders, which creates a firmer edge on pocket sprung mattresses. This is a very expensive process, only done on top quality mattresses.

Hand Tufted

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

Made in the UK

This item has been manufactured in the UK.

Fire Resistant - Low Hazard

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

Additional features

Made by an NBF-Approved ManufacturerPeace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation.
