The flat cardboard form this cover comes on measures 11.25" x 6.5". My Terry bike seat measures 9.5" x 6". Not a cruiser style. It's a road bike style seat tho somewhat vintage. This cover is way too small when stretched over my seat. It won't go over the sides. I tried it on my husband's LLBean Sport Tour hybrid & 2 other seats. Not even close. It seems to be designed for a racing style seat. Those very small, unpadded seats. I'm bummed because it is well constructed & I like the Frida print. I'd recommend it, though, as long as it fit.
