Harrison Spinks Ruby 12500 Pocket Sprung Mattress
Experience premium natural comfort with the Harrison Spinks Ruby 12500 Mattress, available from Bridge Bedding Centre in Essex. Handcrafted in Yorkshire, the Ruby 12500 combines advanced spring technology with luxurious natural fillings to create a deeply supportive, breathable and beautifully balanced sleeping surface.
With up to 12,500 pocket springs in a king size, this mattress is designed to respond precisely to your body, helping distribute weight evenly, relieve pressure points and maintain healthy spinal alignment throughout the night. Its medium tension offers a versatile balance of cushioning and support, making it suitable for a wide range of sleepers.
Advanced 12,500 Spring Support System
The Ruby 12500 features a sophisticated multi-layer spring system combining Cortec™ recyclable pocket springs, HD micro springs and Posturfil springs.
Each spring works independently, adapting to your body shape and movement for more personalised support. This also helps reduce motion transfer across the mattress, making the Ruby 12500 an excellent choice for couples.

Naturally Breathable Luxury
The Harrison Spinks Ruby 12500 is filled with carefully selected natural materials including British wool, hemp, flax and cotton.
These fibres are naturally breathable and help regulate heat and moisture throughout the night. Wool is particularly effective at helping maintain a comfortable sleeping temperature, while hemp, flax and cotton support airflow and freshness.
For customers looking for a luxurious mattress without heavy reliance on synthetic foam, the Ruby 12500 offers an excellent natural alternative.
Medium Comfort for Balanced Support
The Ruby 12500 has a medium tension, offering a refined combination of cushioning and support.
Its multiple spring layers respond progressively as you move, helping the mattress adapt to the contours of your body while maintaining a stable underlying support system. This makes it suitable for many side, back and combination sleepers.
Fully Turnable for Longer-Lasting Performance
The Ruby 12500 is a double-sided, fully turnable mattress.
Regularly turning and rotating the mattress helps distribute wear more evenly and allows the natural fillings to settle consistently, helping preserve comfort and support over the long term.
Three Rows of Hand Side-Stitching
Traditional three-row hand side-stitching strengthens the mattress borders, helping maintain stability right up to the edge.
This provides a more supportive sleeping surface and allows couples to make better use of the full width of the mattress.
Sustainable British Craftsmanship
Harrison Spinks is renowned for combining traditional mattress-making with a strong focus on natural, sustainable materials.
Many of the natural fibres used in its mattresses are grown or sourced close to its Yorkshire manufacturing base, while the use of recyclable spring technology, natural fillings and foam-free construction helps reduce reliance on synthetic materials.
