Sleeping under a conventional, constant-tog duvet, the only method of regulating temperature is in binary: either expose a limb to the cold room air, or don't.

Not so with the Gradient Tog Duvet. Much wider than the bed, it begins as the thickest, plushest quilt you could ever desire, but thins across its width all the way down to a single sheet. Now your temperature control is continuously variable -- to warm up, pull from the left; to cool down, pull from the right.

The double bed version is thickest in the middle, and tapers in both directions (a 'reflected' gradient, in Photoshop terminology).

Yes but is it a linear or exponential gradient?

What if there are two in the bed?

//linear or exponential gradient?// Depends if you measure thickness or insulativity.
