I have a 14.5 inch Kirkey micro/mini self containment seat. I have had it for 3 years and bought it brand new. Ran it in my mini. Still in good condition and is comfortable. The seat padding has a little chew mark in it thanks to my lab pup but still usable. Asking $350. Call or text me at (812)890-3256. If I don't answer when calling, feel free to leave a voicemail and I'll get back to you ASAP.
