The Skeletal Chair at my desk is my favourite seat in the house.
I designed and built this chair three years ago and it has been in regular use ever since. It is comfortable and ergonomic, allowing me to lean side to side or forward, or pivot and turn on the front leg. It is lightweight and can be easily carried with just a single hand. I do most of my writing in this seat, as well as manage paperwork, socialize, and eat the occasional meal.
I like the aesthetics of the design, but have concerns about the strength. I’ve had to repair it four times so far, and that has highlighted the areas that need to be built stronger so that it lasts.
A well-made product should be durable, but the question is, how durable? Is it good enough for an item to endure regular use, or should it also tolerate occasional, or regular abuse such as standing on chairs, lifting furniture by their tops, or being toppled? If a chair intended for adult use cannot support an adult of any size, is that okay? Where is the line between the responsibility of the maker and the user?
If durability was the only concern, we would all be sitting on blocks of concrete. Obviously there are other important factors that lead to a successful design, and each must be carefully weighed in importance, and a good compromise established.
