I have it (in black) and I got it from GW Little too...
It is HUGE!! I have two teapots (both are 12 lbs) and they both fit in it, probably could get another one in there too.
It's very soft and comfy, but mine hate it with a passion, but they like it better than a crate. It has these straps you hook onto the seatbelt and the other end hooks to their harness. This does allow it to have some play in it, because it can slide along the seat belt. It has a nice drawer underneath for storage, too.
But it is really, really big
Also, forgot to mention, it is humongous!!
