It's not what you asked about but something to keep in your pocket for some time you're stumped on another gift for her. https://www.amazon.com/SONGMICS-Folding-Garden-Kneeler-UGGK050B01/dp/B085Y5ZZ4G/ref=sr_1_3?crid=954CLEX9V0JD&keywords=garden+kneeling+stool&qid=1649159400&sprefix=garden+kneeling+stool%2Caps%2C132&sr=8-3 (there are lots of brands and versions if you just search "garden kneel stool". This was just the cheapest listing I saw at a glance.)

Hubby got me one one year. It's dead now because I didn't have anywhere shaded to keep it from the tx sun. But it was absolutely fantastic for my knees. You can flip it one way and sit down or flip it over and kneel. Either way has a small footprint so you can easily avoid accidentally crushing plants with a bigger pad or chair.

Good luck on your quest, though. Sorry I couldn't help with that.
