Support system
The Harrison Spinks Bronze 3500 Pocket Ortho Mattress features an innovative and supportive Cortec™ Quad Revolution® spring system with natural wool for sustainable, breathable comfort.

Individualised springs encased in cloth pockets. Expertly adapting to movement to distribute personalised support to each part of your body.

Small, individually cased springs provide added comfort to the mattress whilst offering soothing pressure relief. Mini springs decrease motion transfer so you can share the bed undisturbed.

Stay snuggly all night long. Perfect all year round, wool is a natural insulator and has great temperature regulating properties.

Natural cotton fibres create a perfectly fresh sleeping environment. The soft fillings regulate your body temperature and wicks away moisture.

Hemp is an eco-friendly fibre that is naturally breathable and durable. It is also a natural insulator so it adapts to any temperature condition.

Naturally durable and strong, flax fibres make a sturdy sleeping environment for enhanced support. Flax is inherently breathable and has anti-bacterial properties creating a fresher slumber.

A traditional technique which creates a sturdier and more durable border. The stylish hand side-stitching method is used to improve longevity and edge-to-edge support.

A traditional and elegant design that holds fillings in place whilst enhancing the stability of the mattress. The luxurious tufting ensures zero shifting, shape loss or sagging.

Stitched into the mattress border, turning handles are there for easier moving and turning. When caring for your mattress, simply use the handles provided for ease of use.

With a single-sided mattress, there's no need to flip. Simply rotate every few months to care for your mattress. Fuss free mattress maintenance!

For the highest standards of quality and safety
The Harrison Spinks Bronze 3500 Pocket Ortho Mattress is designed to offer lasting support and dreamy natural comfort.
Pocket springs
Featuring 1000 Cortec™ Quad Revolution® pocket springs, this mattress offers innovative support. Designed with a small spring for support placed inside a larger spring for comfort. Each dual spring is placed into a cloth pocket and secured together in groups of four. This increases the responsiveness of the springs, helping them adapt quicker to your movements and provide full body support
Micro springs
Layers of 2500 micro springs provide additional bounce that is adaptable to your body. Their small shape means they have greater points of contact with your body, offering ultimate comfort. Mini pocket springs can help increase breathability within the mattress. Small gaps between the springs create room for airflow. Promoting a fresher feel and reducing moisture build up.
Natural fillings
A layer of British wool provides a plush and sumptuous sleeping surface to keep you feeling extra comfortable all night long. Wool is naturally temperature regulating for a refreshing feel in summer and cosy bliss in the winter months.
An additional layer made from a blend of cotton, hemp and flax wicks away moisture to enhance the fresh feel. This can also help reduce a build up of mould, mildew and odours within your mattress.
Completing the comfort layers of the Bronze mattress are layers of robust hemp and strong Ecotex fibers. Both these layers add strength to the mattress, helping to reduce dips to the surface so you can enjoy its comfort for longer.
Treatment free cover
The mattress is finished with an in-house woven, FR chemical-free cover, crafted to meet fire safety standards naturally while maintaining a healthier sleep environment.
Turn free
Designed to be single-sided this mattress requires no flipping. Simply rotate it top to toe seasonally to keep it in the best condition.
Lasting quality
Backed by a 5 Year Guarantee and a 5 Year Warranty thereafter, the Bronze Ortho offers you 10 years of assured quality.
This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.
