Most hybrid mattresses have 1,000 to 2,000 springs and a few layers of different foams. This one contains 7,300 springs, five layers of foam and various temperature-controlling natural materials. There are 11 layers in total, which might sound like overkill, but once you’ve slept on it, other hybrids seem like works in progress.

So, what do they all do? Well, the base is basically an entire pocket-sprung mattress in its own right, and it’s what gives the Ultra its bounce. Above that are a layer of smaller springs and two layers of yet smaller micro-springs arranged to support the hips and shoulders.

Other hybrid mattresses claim this kind of contouring, but the Ultra is the first where I can feel it; I have a bad back and this helps align my spine, reducing pain.

Another function of the micro-springs is to stabilise the edges. There’s no droop at the sides, so you can use the whole width of the mattress – an important consideration when two people share a double.

Finally, you’ll notice the thermoregulation. Towards the top are layers of natural fibres – including coconut, wool, bamboo, charcoal and kapok (a light and airy plant-fibre) – topped by a soft knitted cover.

They give a gentle, floaty feeling and significantly reduce night sweats. It feels cosy in the cold too. I tried the Ultra as the seasons were changing and the temperature dropped by 10 degrees – it works.
