No, if the keyboard is properly adjusted, no bounce should be experienced when typing. It is necessary to set the keyboard up to be stable on its four feet to stop any wobble. Pull the locking bar mechanism out. With the right hand lifting the back of the keyboard from underneath, place the left thumb on the Goldtouch logo and pull the handle back into the locked position. Each half needs to be pretty even for it not to rock or bounce. If the keyboard still wobbles, pull the locking bar out again and adjust it slightly until you feel the two halves are stable.
