[Spridgets] Seat options

[pelliott at innercite.com (Patrick Elliott)]

I need seats for my 1962 MK2 Sprite.

What fits?  Who sells them?  

I have two little buckets I bought 12 years ago, but they hurt my ever
widening posterior.  I have the option of getting them recovered and foam
added for $300 each. I found something similar on Ebay for $595 each..

I see that I can get a pair of Miata seats for under $200, but do they fit
without the back being straight up and thus uncomfortable?

Any other options?
