What is the maximum weight that the Alps Mounaineering dual action chair can hold?

You can find replacement springs for anything at any hardware store. The heavy duty spring on my sisters recliner broke and the chair would not stay down. I found the original spring laying under the chair with the hook broke off one end. She went to a local hardware store and they had springs that were the right length and proper pull weight, got one and brought it home. I turned the chair over, opened it up and put the spring on, closed the chair up and set it upright and it works perfectly. So don't tell me you can't find a spring to fix your little scooper. Go to the hardware store.

(You didn't say which chair.) From a warranty sheet that came with a chair: "Warranty is limited to normal usage, not exceeding 40 hours per week and 250 lb. weight."

Cheaper chairs can have lower ratings.

well have you ever thought about loosing weight because if you sit in a chair and it creaks that means that the chair is just trying to hold you up.

This is most likely a case that the controller/computer(the box that the joystick plugs into down inside the chair)is placing the chair into what is called a "limp-home" mode. It automatically senses something seriously wrong with the chair and starts cutting the power to the motors, such as overheating. If they are still getting hot, it will shut itself down completely, and you can restart after all cools down, but you have a serious problem on your hands. This usually happens when a chair is loaded near or past its maximum weight, and say you try to drive it up a long incline....motors will overheat and it will slow down, then shut down. If it is doing it on a flat surface without being heavily loaded, you have motor problems or controller problems.

i think these chairs are rated at 100 kgs

Electric massage chairs have some disadvantages:

• They are very expensive- cost at least $1,000, but usually much more.
• They are very heavy, so they are quite difficult to move around.
• Because it reduces blood pressure, it is not advised for people with low blood pressure to use these chairs.
• Some chairs can only hold a certain amount of weight.
• They are not as effective as getting a massage by a therapist.

heavy duty beach chairs can hold a capacity of at least 280 pounds. Some chairs can hold even 400-500 pounds.

A folding beach chair is a type of chair that's made of lightweight materials and can be folded. These chairs are also very easy to move around because they're so light.

Each manufacturer has their own weight limit published, so I advise asking in advance. From my research, it seems that most chairs can hold up to 270lbs; although there are some models that have a higher capacity.
