What will we do with your old bed/mattress?
We will do one of three things:
- A local charity may want it. We have given them many items in the last year
- We may recycle the mattress
- Some mattresses cannot be recycled, and so we use a local disposal service to take care of the goods.
Product Description
The Triple Firm Mattress is a very supportive hybrid mattress designed to deliver comfort and stability for those who prefer a firmer sleeping surface. This orthopaedic mattress combines advanced pocket spring technology with high-performance foam. As part of the range of three mattresses within this collection, this is certainly the firmest, although you can also choose the Soft or Medium options, all with the same price and specification (aside from the firmness!).
At the core of the Triple Firm Mattress are 1500 pocket springs (based on a king size). Each pocket spring reacts independently, moving up and down like a piston, as your body moves throughout the night, promoting correct spinal alignment and helping to reduce pressure points (the main cause of aches and pains some people wake up with). This spring type will also minimise motion transfer, making it a practical choice for those who share a bed.
Above the 1500 pocket springs is a layer of Cloud Lite foam, a modern alternative to traditional memory foam. It offers a firmer feel while maintaining breathability. This foam is designed to be comfortable and also to improve airflow and temperature regulation throughout the night, helping sleepers remain cool and comfortable.
The mattress is constructed with durability and ease of use in mind. It is a single-sided, no-turn design, requiring only rotation (spinning around) to maintain even settlement. We recommend this be done every 12 weeks or so. A ventilated mesh border around the sides helps improve breathability, while the soft-touch, knitted cover provides a smooth and comfortable finish. Integrated handles are stitched into the sides to make rotation more manageable.
The Triple Firm Mattress is manufactured in Yorkshire, England, and is available in a range of sizes, including single, small double, double, king and super king. Ideal for anyone who prefers a firmer mattress feel, the Triple Firm Mattress offers reliable support with modern materials. Combining the proven benefits of pocket springs and cool, responsive foam, it’s a practical option for those seeking a mattress that balances firmness, airflow and durability - as well as value for money!
