Bearing in mind rockers go through a lot of movement it makes sense to choose a heavy duty rocking chair. The continual rocking motion will create a lot of stress on the joints.
If they start to loosen and don’t get fixed immediately a pile of sticks will be the only outcome.
Plus the fact if the user were to be overweight then this would further compound the problem. The first 2 in my list of five are designed to take weights of up to 600 lb.
This type of seat is meant for relaxation. Although I don’t visualize much relaxation taking place when listening to the sound of squeaky joints.
See my list below for some suggestions.
