Dogs that sleep with their head up need something to put it on, and a flat mat gives them nothing, which is why so many end up with a chin hooked over the edge or draped across the arm of your sofa. An L-shaped bolster puts a raised back and one raised side into the corner they already choose, so the head is supported and the spine stays roughly straight through the night.

Five sizes run from 91 by 69cm up to 137 by 91cm, with the base 15cm deep on the three smaller ones and 18cm on the two largest. Fill is your choice: shredded sponge, which moves and moulds around a dog that shifts in the night, or egg cotton, which holds a more even surface and springs back. The cover unzips and goes in the machine, which is what decides whether a bed lasts.

On sizing, and on colour. Those dimensions are the outside of the bed, and the bolster eats into the lying area, so measure your dog stretched out and go up a size if they sleep flat.

Who it's for: Dogs who sleep curled or leaning, older dogs wanting their joints off a hard floor, and anyone tired of washing a bed that will not unzip.
