I ride one of the ponies in a Best Friend one. It's cool, has a grippy underside and faux suede upper-best not to use it with sticky bummed breeches a friend has a christ lammfelle one and it does look comfy.
Do NOT use stirrups if you get a pad with them on. They create nasty pressure points (mine would be across the withers).
Although I love mine. It has a little handle for Indy's little spins. Bought it in Canada so I can't really help with UK availability, sorry.
