Wish I invested sooner
King of the springs is the best investment we’ve made in our sleep. The perfect balance of support and cushioning, we have never slept better since ditching synthetic and moving to our wool mattress and wool bedding. So glad we found Floks - their products and their genuine care and support as a business are such rare gems.

If like me you love sleep
If like me you love sleep, you will LOVE this mattress. It’s just been transformative for my sleep, I can’t wait to get into it at night and I hate leaving it in the morning. I actually hate sleeping in hotels now, the beds are never as comfortable.

FAQs
A British Wool mattress offers naturally breathable, temperature-regulating comfort without relying on synthetic foams. Wool responds to your body's changing temperature throughout the night, helping keep you warm in winter and cool in summer while managing humidity around your body.
Unlike many conventional mattresses, a wool mattress also naturally resists dust mites and bacteria, making it an excellent choice for healthier sleep. At Floks, every mattress is handcrafted in Yorkshire using traceable British Wool alongside hemp, flax and thousands of precision-engineered pocket springs.
No, they’re one of the coolest options. Wool draws moisture away from your body and regulates temperature, so you sleep cooler in summer and warmer in winter. Foam mattresses can trap heat, while wool, hemp and flax let air move through the mattress all night.
Yes. If you often wake up feeling hot or sweaty, a wool mattress can make a noticeable difference.
Wool fibres absorb moisture vapour before it becomes sweat, helping reduce overheating and creating a drier, more comfortable sleep environment. Combined with breathable natural fibres and pocket springs, wool allows heat to dissipate more effectively than foam mattresses.
The healthiest mattress is one that supports your body while creating a breathable, low-chemical sleep environment.
Floks mattresses are:
- Glue free
- Naturally fire resistant without added FR chemicals
- Made with breathable British Wool, hemp and flax
- Handcrafted in Yorkshire
Natural materials help regulate temperature and humidity while reducing reliance on synthetic materials commonly found in conventional mattresses.
Yes. Floks mattresses are naturally fire resistant thanks to the high wool content, meaning they do not require added FR chemical treatments.
Every mattress is also completely glue free, using natural upholstery layers and recyclable pocket spring systems instead.
At the heart of every Floks mattress are generous layers of traceable British Wool, paired with hemp, flax and pocket springs. There’s no foam, no glue and no chemical fire retardants, because wool is naturally fire resistant. Each mattress is handcrafted to order in Yorkshire, so it’s made for you rather than sitting in a warehouse.
