"TRUE INNOVATIONS"

 TRUE INNOVATIONS  is the name of the company who made our computer chair.  They were nice enough to send a replacement part when our chair malfunctioned, even though the warranty period had passed.  The seat of the chair would gradually sink so at the end of a session at the computer, your chin would be at the level of the keyboard. 
    Evidently the faulty part was a gas lift.  The instructions explain how to install the new part.  
         1) "To remove the gas lift, keep the chair upside down.
         2) Use a hammer to hit around the area where the gas lift fits inside the seat plate while pulling out the gas lift.  These two items are locked together by pressure; the more you hit the seat plate and pull on the gas lift simultaneously, the more pressure will be released.   Eventually the two items will separate."

Stamped on the part, which, incidentally, weighs almost three pounds, is the caution, "Do not open or heat up."
I had never before  considered the possibility that I  would be afraid of a chair.
