Sometimes my back is good, sometimes it’s bad. When it’s bad, it can be very bad, right down to my knee.
We have some pretty pricey furniture in our home. I can’t sit too long on any of it.
My go to spot for most of my sitting is at my desk in an office chair. Price isn’t that important with an office chair as long as you don’t get the very cheapest. My current one is from Wayfair and was about $200. What is important are the adjustments. Make sure you get one that has adjustable tilt and adjustable height. My armrests are adjustable too. I can sit in it all day long with no problems.
Hope this is of some help because back pain really sucks!
