This is, without a doubt, the most luxurious seat pad you will ever come across. 

Dimensions: Outer inc overflow 57cm , Inner circle 55cm 

Note that sheep are individuals, like the rest of us, so if you buy more than one of either type, the seat pads will be somewhat similar but not the same. Its a natural product, so thats just the way it is.

Made in Galway from Galway sheep.
