You should always invest in your comfort. Moreover, physical and mental comfort deserves equal costs. I think that if you feel good physically, your mood will also be better. So, it's a double investment. I spent a lot of money on comfortable garden furniture from gardenfurniture.co.uk. Because I like to spend time outside, read a book, and cook meat on the grill. I felt guilty about the purchase because there are always other options to spend. But I feel so great, the regular chair makes me happy every day. I think it's worth it.

I wouldn’t get that chair, but I would spend that much on certain concerts tickets. It’s about intrinsic personal value. I know you posed the question, but your the only one that can answer it.

Happy birthday in advance.

First, HAPPY BIRTHDAY!! Second buy you a good bottle of spirits and a bean bag chair....OLD SCHOOL GAMING at its best!!

0% interest... hmmmm..... Call it your "going to the movies" chair and think of a movie ticket & popcorn once a month, maybe? That'd be what? $17? so pay $17 on it every month and in 2 years its paid for. No stress, fair swap. And you deserve a movie once in a while.

Do it! if its going to relieve your pain, there's no price you can put on it

Do it. I sit at work all day - and when there's a deadline, several hours after closing time - only getting up for short periods. I require a good chair. As a freelancer, my work place changes often. And the beat-up chairs at offices are always left aside for us freelancers. A good chair is almost always the first thing I request when starting at a new company.

Can you test sit on these chairs? Or are they online?

I have an Autonomous chair that I am quite happy with. Looks like the sell from $250 -$300 per Google shopping. I work from home as a software developer and have had neck issues off and on for more than 15 years. That chair makes a world of difference for me - I really like it and my neck is much better now. It is also affordable compared to some of the fancy Aeron chairs that cost an arm and a leg. [autonomous.ai]

Treat yo self! Plus that's a very reasonable place to do it. The chair I have is twenty years old. It's worn terribly but it's still comfortable.

I feel like spending the money on something that you plan to use so often is a sound investment into your own wellness and happiness.
Happy birthday by the way.

If you can afford it don't feel guilty. Life is too short. If you have a lot of back pain try yoga. It can help a lot.
