For the highest standards of quality and safety
The Gainsborough Mayfair 5000 Pocket Mattress delivers full body pocket sprung support and cosy comfort from natural fibres.
Pocketful of support
Enjoy the soothing support of 1000 traditional pocket springs. Fashioned from durable material, these springs are shaped to hold a supportive bounce. Placed in individual fabric pockets and secured together so they respond to your individual movements. Highly reactive, the springs adapt to your body and ensure you receive the support you need. Helping to promote better spinal alignment and ease any aches or pains.
The smaller size of the 4000 mini springs helps them contour to your unique shape, offering adaptable comfort. These springs also offer greater airflow through the mattress to help reduce the build up of moisture, heat, mould and odours.
Layers of comfort
Experience blissful comfort with layers of sumptuous natural fibres. A blend of wool and cotton fibres create an ideal comfort layer. The natural properties of wool offer rebound comfort and extra durability to your mattress for longer use. Wool and cotton are excellent at wicking away moisture for a fresher feeling mattress.
An additional layer of cashmere, wool and silk provides comforting cushioning. These natural fibres are great insulators, offering cosy warmth on cold winter nights. Inherently breathable, they are also perfect for the summer. Ensuring there is constant airflow that keeps the mattress feeling fresh and crisp, for ideal seasonal use.
Better for you
Treated with Ultimate Freshness anti-allergy treatment to offer reassuring protection. This is an anti allergenic treatment that protects you against dust mites. This can reduce contact with mites and provide a safer surface for your skin, easing irritation.
Edge to edge protection
The border is complete with Gainsborough's exclusive PowerEdge system. The design features two wire rods along the top and bottom of the mattress border. They are secured in place with butterfly clips. Enhancing the durability of the mattress edge to stop it from sinking when met with weight. So you can sit or sleep right to the edge without the dreaded ‘roll-off’ feel.
This mattress has been hand side stitched which is the process of stitching the spring system to the side panel. This feature keeps the spring unit securely in place. Delivering further durability and stability to the mattress.
Three decades of expertise
Gainsborough established their brand over 30 years ago, focussing on pocket sprung support and finding the finest fibres to place on top. Their manufacturing site is a 100% zero-landfill facility, utilising recycled and recyclable materials.
Complete with a 10 Year Guarantee to protect against any manufacturing fault should they occur during this period.
Please note: pocket spring count is based on a king size mattress.
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.
