This adapter securely holds 12 oz and 24 oz mason jars, along with most large mugs and glass cups, so your drink stops leaning, wobbling, or living on the floor next to the couch.
Made for couch and chair cup holders
It's designed specifically for furniture-style cup holders. The outer diameter is slightly larger than a standard can, and the added height helps it clear the armrest next to it for a better, steadier fit.
Holds mason jars securely without tipping
Works with larger cups that don't fit standard holders
Simple, clean design for home use
Great for recliners, couches and theater seating
Important fit information

A note on 3D-printed parts
Every piece is 3D printed and hand finished in the USA. Because of the way 3D printing works, you may notice small differences in surface texture or color from one piece to the next, or from the photos. None of that affects how it fits or works. I'm always testing and tweaking my designs, so the one you get may include small improvements over what's pictured.
