I initally had the assumption (no idea why) that I was supposed to spend most of my time standing if I had a standing desk. Initially I thought standing desks were not for me because I'd start to feel tired after 20-30 minutes. I've now learned that a far more effective approach for back pain and general good posture is to vary your position every 20-30 mins. i.e. got from standing to sitting, or sitting to kneeling (if your setup supports it). The more viable postures you can use, the better.
To enable this, I have invested in an Hag Capisco chair, which supports multiple postures: https://store.flokk.com/uk/en-gb/products/hag-capisco Again, I initially thought it wasn't for me until I realised how it was meant to be used. The intention is to mostly sit on it with the small of your back unsupported, like you're on a stool, but with the option to relax and lean back when you get tired. I now spend very little time in the traditional sitting posture and change regulary to sitting sideways, backwards, or even kneeling on the chair. It's not for everyone but it's made a huge positive difference for me. Places that sell these will often let you try them or hire them for a few weeks to see if you like them. I'd strongly recommend having a go.
Additionally as others have mentioned, having a standing mat is a big help. I used to find that the soles of my feet would become uncofortable quite quickly. The solution I am using now is an Aeris Muvmat https://en.aeris.de/products/aeris-muvmat-schwarz-ohne-bezug which appears to be flat, but actually has irregular hard lumps under the surface. It's designed to mimic the feeling of tree roots on a forest floor. It encourages you to keep moving your feet around without you really relaising you're doing it, effectively massaging your feet slowly, so the circulation keeps going and the soles of your feet don't get tired. Thsi has been really effective for me, so highly recommended.
I dont recommend the capisco for work where you are very concentrated, such as software development. I do however like it for meetings and presentations.
