Our sleep team loves connecting with our customers - listening closely, learning from their experiences, and taking feedback to heart. Through these conversations, one thing has become clear; our customers are more than willing to invest in creating their ideal sleep environment, recognising the impact it has on their rest and overall wellbeing.

Inspired by this commitment to better sleep and creating the superlative sleep environment, we developed the King of the Springs mattress. Luxuriously crafted and sustainably made, it offers a medium-to-soft feel that’s both supportive and indulgently comfortable. The result? The ultimate in natural sleep luxury.

If you'd like some help choosing which of our luxury wool mattress range is right for you then you can get in touch with our sleep team at hello@floks.co.uk or have a read of our Buying guide: choose the best wool mattress for you.

The King of the Springs is hand-filled with a generous amount of British, Yorkshire, Herdwick and Swaledale wool, blended with UK grown hemp & flax. These natural, breathable and sustainable fillings offer you the most comfortable nights sleep.

It's not just the fillings that are important to us - our mattresses are topped with 100% British wool, cleverly woven (in Yorkshire) into our very own sustainable, breathable and anti-allergenic Floks mattress ticking.

Our mattress springs (also made under the same roof in Yorkshire) provide the all important springiness and comfort in our mattresses. These springs are made to be fully recyclable, and just like the rest of our mattress materials, are made without the use of any glue, foam or fire retardant chemicals.

At Floks, we partner with Harrison Spinks - pioneers in self-sufficient, vertical manufacturing, to bring you mattresses that are as kind to the planet as they are to your sleep. Every component is grown, woven, and made locally, ensuring the highest standards of comfort, durability, and sustainability.

Dual-sided design for longevity

Our dual-sided mattresses offer two sleeping surfaces, made from the exactly the same materials. This ensures both lasting durability and enhanced comfort.

In order to deliver exceptional edge support and to reinforce this mattresses premium craftsmanship, we have used four rows of hand-stitched side panels.

Advanced pocket spring technology for tailored support

The King of the Springs mattress has 750 Cortec core unit quad springs. These add the tension and give the overall 'bounce' and regular or firmer feel to your mattress.

As well as the mattress tension springs, additional comfort is created with the use of pressure relieving high density pocket springs. These hard-working little springs help to disperse your body weight and keep your spine optimally aligned for maximum comfort. This being our most luxurious mattress, we added more of these pocket springs into this mattress than any of our other mattresses - 2 layers of 2500 and 1 layer of 4000 high density pocket springs are layered on both sides of the mattress.


Available in either regular or firm tension options, and in a single tension, split tension (two different tensions in the same mattress) or a zip and link mattress.

Please note that our mattress and mattress enhancer lead time is 4 - 6 weeks. Pricing includes delivery.  Bespoke sizes are available upon request.  

With a little bit of care your mattress will help to support your sleep for years to come.

If you can, allow your mattress to breathe for a couple of days when it arrives with you.

Regular flipping of your mattress will promote longevity. We recommend to turn every week for the first 12 weeks, then turn seasonally.

Turnable vs. No-Turn Mattresses: Which One is Right for You?

At Floks, we offer both turnable (dual-sided) mattresses and no-turn mattresses, so you can choose the perfect sleep solution for your needs. Here’s what sets them apart:

Turnable (Dual-Sided) Mattresses: Long-Lasting Comfort & Durability

A turnable mattress is designed with two identical sleeping surfaces, allowing you to flip and rotate it for even wear and a longer lifespan. By alternating sides, you help maintain its structure, support, and comfort over time.

How to Care for a Turnable Mattress
  • First 12 weeks: Flip and rotate weekly to help it settle evenly.
  • After 12 weeks: Turn seasonally to maintain its shape and support.

If a mattress isn’t fully turnable, it will need to be rotated rather than flipped to ensure even wear.

Turnable Mattresses in the Floks Range:

✔️ Perfectly Floks Mattress – Balanced support with natural materials.
✔️ Highly Sprung Mattress – Superior comfort with extra spring support.
✔️ Floksy Topsy Mattress Enhancer – Extra layers of comfort for a plush sleep experience.

These dual-sided designs offer exceptional durability, ensuring your mattress feels just as good years down the line.

No-Turn Mattress: Effortless Comfort & Support

A no-turn mattress is a low-maintenance option designed to be rotated rather than flipped, making it an excellent choice for those who prefer a simpler sleep solution.

Why Choose a No-Turn Mattress?

✔️ Ideal for those who want to avoid heavy lifting.
✔️ Perfect for those who love the plush feel of a Pillow-Top mattress.
✔️ Designed for minimal upkeep while still maintaining long-term comfort.

With one dedicated sleeping surface, a no-turn mattress delivers effortless relaxation—so you can focus on getting the best night’s sleep, night after night.

No-Turn Mattresses in the Floks Range:

✔️ Floks Away Mattress – A breathable, handcrafted mattress made from 100% Yorkshire wool, hemp, and flax.
✔️ Pillow Top Mattress – Luxuriously plush with an extra layer of soft cushioning for a cloud-like feel.

Which Mattress is Right for You?
  • If you want maximum longevity and even wear, a turnable mattress is the way to go.
  • If you prefer a hassle-free, low-maintenance option, a no-turn mattress is a perfect choice.

No matter which you choose, every Floks mattress is crafted from natural, sustainable materials, offering superior support, breathability, and comfort—for sleep as nature intended.
