I use a car seat organizer with one of these on the passenger seat. I pushed them both into the gap at the same time and adjusted them to the position I liked. Very strong together and I can use a mug with it for a mug I keep for everyday items (dishes, sauce bags, etc.). The organizer is black with brown leather trim at the top. Perfect fit for my phone. Driver seat gap only with other gap filler. I don't use a second cup. The cup loop nestles snugly against the end of the gap filler. You don't even notice it without a drink holder. I like the loop that goes over the seat belt clip more than trying to put the clip through the cushion gap filler. The seat belt is also easier to put on. Nice design finish, slightly more upscale. I went for black and I think it looks pretty cute. They are zipped so you can add more padding if needed. Once you pinch it in the top it will flatten out. I think it looks nicer than the puffy whitespace type. The upholstery has a slight curve to fit most car seat shapes more naturally. They can be wiped clean with a damp cloth. Overall I think I got a good product at a good price.
