I have two fully Jarvis sit / stand desks. One at home and one at my coworking space.
There are mats and balance boards you can stand on to keep your balance moving around which makes standing less…boring?
I have to remind myself to stand up and set a timer to take a seat again. It can help vary things up a bit.
It’s somewhat pricey, esp w the accessories I mentioned. Supposedly this can be a big contributor to health though, so hard to put a price on that.
I also put some time and a little money into the under desk power and cable management basket and a high watt power strip so only one cord would hang.
It all takes time and money and then you gotta use the stuff but it’s nice.
I’d suggest investing in a nice office chair first.
