is olive canvas, which they say is the original color. It's slightly off from the other seat cushions, and the Beachwood Canvas top. Those look a little more tan. Any opinions on this?

These are the seats. The one on the right is the original (and is the same color as the upper seat cushion, the back seat, and the top). The one on the left is the new one from Kaiser-Willy's.

It's easy to just say Olive is the original color. From what I've seen, your one on the right looks correct. I don't think you would ever get a solid match just buying from 1 seat or what ever and hoping it matches up with what you already have. Given time and the elements, what you have could of faded. And who's to say your one on the right is original anyway. Only sure way of getting a match thru an online vendor is buying a whole set or going to an upholstery shop and laying down samples next to your existing material.

Ok, but you know what's strange? They sent me an upper cushion that I didn't need. I sent it back and they sent me the lower cushion. The upper cushion was the right color.

I kind of hate to do it, but the seat cushion canvas is simply stapled on to the bottom of the seat. I could take the shorter cushion, swap it into the old seat canvas, and just have more material I need to staple to the wooden baseboard.
