Reddit reviews TiiL Universal Car Seat Cover, Quick-Dry Microfiber Seat Protector with Storage Bag, Absorbent and Non-Slip, Machine Washable, Fit-Towel (Black)

I’ve got these TiiL car seat cover, I’ve had them over a year, used 3-4 times a week after running or the gym and so far no stink! I give them a fabreeze every once in a while and pop them in the washing machine when needed. So far so good.

I've purchased 2 seat covers in the past 2 months. The first one I bought was this microfiber towel. The second one was this neoprene one. I ended up hating the microfiber one for a few reasons: after even one use it stunk terribly, it wouldn't dry overnight if i hung it up, and the whole strapping it to the seat thing was a pain in the ass (not difficult, just annoying). The neoprene one I only got recently but it just slips over the headrest and tucks in. The rubber backing means it doesn't slide too much and is actually waterproof. Best part was that it has actually dried overnight and not smelled horribly. My seats are black cloth so I didn't really worry about color transfer but make sure you don't just leave whatever cover you purchase on the seats permanently, that's not what they're meant for.
