"Of the time honoured quality fillers that go into the most expensive world-famous mattresses, barring the use of horsehair, I chose quality soft weave rebounded cotton fibre to be our breathable and flexible support barrier which surrounds this Ultimate mattresses spring unit. Its natural fillers are readily available within a low impact environment. I chose organic wool because it is of such great comfort, as well as being incredibly responsive to our 'homeostatic' need to self-temperature regulate, which means being able to cool down and warm up easily throughout the night, allowing the body to temperature regulate freely. I added as much organic wool as practicable to achieve the desired firmness rating. The cotton barrier pad surrounding the spring unit breathes really well, allowing for continuous airflow, consistently good comfort and support as the years go by. All the constituents of this mattress are hand bound together with wool finished tufts. It is a single sided mattress which encourages the air to move through it more than any other mattress, and of course this makes it easier to manage when only needing to rotate it regularly. A Fantastic Mattress!" (Warren Evans)

The GOTS certified British wool we use maintains the flexibility within wool fibres so that the strands bounce back again and again, crucial to enhancing the properties of wool helping it to:

  • Wick away moisture, removing heat when you're hot and insulating you when you're cold
  • Reduce the moisture held in your mattress, vastly increasing the healthy air and creating a micro fungi free environment
  • Completely deters dust mites from being in or breeding on organic wool, reducing asthma and allergies
  • Naturally resistant to bacteria and fungus growth

Most manufacturers will not use organic wool because of the inhibitive cost, especially as it is much harder to machine, prepare and manage, but we know its well worth it!

The Air Sprung unit provides a 'tri-level support' accommodating individuals of various weights and sizes.

The Air Sprung mattress is specifically beneficial for people across the weight spectrum, accommodating all types of sleepers. As weight increases in particular places on your body, the top and lower spring become engaged and resist excess indentation and spinal curvature which causes lower and middle backaches.

The design not only allows lighter individuals to experience comfortable support but also ensures robust support for those with a heavier weight. It delivers exceptional uninterrupted sleep with 'no roll' and jiggling motions disturbing sleeping partners.

This mattress has an exceptionally responsive and comfortable spring unit which over the years, outperforms a traditional pocket spring. It responds to your body's shape, delivering consistent year in, year out support. The patented German Air spring responds in a three-dimensional resistance pattern that allows for continued comfort and uncompromised support. As the fillers of all mattresses age, giving less and less soft arch support, these springs will continue, year after year, to feel as comfortable as they did on day one. Good-quality springs do much more as a support provider than anything else for long-lasting comfort.

"It's a truly lovely mattress to sleep on. It's made the last 3 years of sleeping on it a lovely sleeping experience." (Warren Evans)

When purchasing a natural mattress with no foams, rubber or latex materials inside, one is confronted with a brand new smell. Instead of it being the scent of glue, rubber or foam, this mattress will smell of a beautiful field with horses. The smell dissipates quickly and poses absolutely no harm from 'forever chemicals' found in man made foams, chemical fire retardant sprays, rubber, latex, glue and so on..

All of the wool within our mattresses is from British sheep and has been GOTS certified!

Velcro Link is available in king-size mattresses and larger.

I've slept on a lot of mattresses over the years, but nothing comes close to this. I wake up without any back pain for the first time in years it's genuinely changed my mornings.

We were hesitant to spend this much on a mattress, but after six months we wish we'd done it sooner. The quality is evident from the first night. Worth every penny.

James & Louise T.

Delivery was smooth, the mattress arrived rolled and set up beautifully within hours. It feels luxurious without being too soft exactly what I described when I called the team.

Two years in and it still feels like new. No sagging, no springs, nothing. Warren Evans clearly make things to last I'm already planning to order a second one for the guest room.

Natural Smell & Care Information

We only use British organic wool in the top sleeping layers of all our mattresses, because it is so much better for a deep sleep. It takes the heat away from your body when you perspire and keeps you warm; and if you are perspiring, wool assists in cooling the sleeping surface more than any fibre known to Man. It is how sheep live through the coldest winters and very warm summers; nature's miracle fibre, never matched by anything man made.

It is essential to our health that our body can cool down and warm up throughout the night so that it can reac and maintain the deepest forms of sleep. This is called homeostasis and is necessary for a full physical and mental recovery from the day previous days challenges, whatever they are and whatever age you are. Mixing organic wool with great ventilation underneath and within our mattresses is our manufacturing and design specialty. Comfort and support are in fact not as important as good homeostasis, but why choose when you can have all three?
