Not a problem at all. We have removed that chair and the little tv cabinet and installed a larger cabinet for the flat screen tv with storage under it for our vcr, dvd, and satellite reciever. Only have the chair by the door now. Lots more room!
The chair is fastened to the floor with four bolts through the base and with nuts under the floor. You will need to slide the battery drawer out to get at the nuts. Be sure to plug the holes when the bolts are removed. Pretty much takes two people to remove the nuts and bolts.
