I wanted something similar for my terrier - but only so I could fit it between the two front seats in our camper van, so she could face forwards but snooze comfortably.
Ended up making it myself, and I'm not great at such things. At least you can choose a nice fabric and stuff it firmly so it's just right - I used an old bedspread and the filling from some cheapo pillows, took the measurements and cut it out on my landing. The dog laid on it when it was still a template!
I have a small lurcher (large whippet size)and she could do with a longer bed, but each size up, the beds get longer AND wider. I don't actually need the bed to be wider and think we'll all end up tripping over it if it is wider.
Does anyone know of a dog bed company who sell/make beds which are long and narrow? 100cm x 50cm would be ideal, but even 90cm x 50cm would work.
Small problem I know - just curious if anyone can point me to what I want or if I will have to make it myself.
