Buddy Seat with ENGLISH saddle

I've found some buddy seats to use with an English saddle and wondered if anyone else had used them?

I also found another horse who would possibly be better suited for my hubby than Gracie bc it is kid safe, double safe and pony-up safe. He's also almost 3 hrs away! Going to talk to the hubby to see his opinion.

Chele, don't want to sound discouraging but some sellers do lie (or should I say exaggerate ) about their horses. What is advertised as "kid safe and bombproof" may be something hyper only owner can ride. 3+ hours drive just to look at the horse is LOTS of time (and gas). So unless you are sure about what want to look at I wouldn't drive that far. I mean, of course it MAY be a great horse and all and its up to you, but can be just wasted time.
