How Wide are MX5 Seats?

[Enoch]

As per the title really. I am looking at what options I have for seats, in my last build I used the Mamba club seats but they were terrible quality. Tryng to find a seat from a production car that will fit. Can anyone with an MX 5 build measure the widest point of the seat and let me know the measurement please? If anyone has any other ideas what might fit I would welcome any suggestions. I don't want buckets or racing type seats, don't think they would look right.

PS the budget is virtually non existent so can't afford new ones.
