I'm looking for a relatively cheap and comfortable armchair or beanbag that can hold my 193cm and 110 kg and in which you can take a half-lying / sitting position. As a software developer I stick a lot to the notebook and can concentrate and work best in the above position, I'm now looking for such a seat
Are there any recommendations?
Your idea and the long-term working posture in a beanbag are of course not sensible and ergonomic. There's a current (advertising) test of image with relevant bean bags. Here I can really only recommend Fatboy's. Vlt. Get a reserve bag of polystyrene balls right away. Firstly, you can then fill tighter (there's an inner sack) and secondly you need to refill material after a while.
I advise you to get advice in a seating furniture shop and to test different furniture for long-term effects.
Crouching, sitting or slouching on the floor is not a good idea. Vlt. Would be a recamiere an approach.
