Okay, this is a silly thing to give an entire blog post to, but I’m doing it anyway.
The Masterlink Seatbelt Adjuster is a small plastic clip that attaches to the waist portion of a seatbelt and offers a little flap so that you can tuck the shoulder strap into it.
(Please note I linked to an amazon search for it because I only paid $6 for a two-pack of black ones and the prices seem all over the board now.)
As a short lady, I cannot imagine how much this has made my driving life easier. Even having to re-do the shoulder strap every time I sit down is minimal compared to the lack of choking/cutting pressure on the side of my neck from the shoulder strap.
I gave the second one to my mom and she reports similar results — took a week or so to get used to slipping the strap through the latch and now neither of us can imagine driving without it.
Inexpensive and useful. My second favorite combo. (If it was also adorable it would get extra points).
