Not worth the wait & the bands aren't stretchy enough
Color: Red
Doesn't fit on a Cadillac XT6. The console isn't flat underneath and the stretchy band can't go through all the little bumps. Too tight. Plus the back part of fhe console has no space to pull the band through so it essentially flaps around freely. Color is a 80% match also

Worth it and it fits
Color: Black
This this is the cutest. It’s so fluffy. I appreciate the packaging. It is super fluffy once it’s out the packaging. I try not to place my arm on it too much which keeps me come flattening the material and abusing the arm rest. It’s comfy and flash. I can’t wait to finish decorating the inside. I’ll have to update with a photo

Cute but didn’t fit
Color: Red
Did not fit my console. It’s a bit small. I did measure my console before I ordered it, but it didn’t fit. It is really cute. I do have the steering wheel clever and seat covers that match this.

Happy customer!
Color: Black, Color: Black
Love it, mine came in all black underneath the fur and the straps. 🖤 (try combing out with fingers rather than brush so you don’t have too much shedding)

It doesn’t fit my armrest !
