The answer to this question is so easy! It's a coffin.
The maker doesn't want it because he or she is not dead.
The buyer doesn't need it because he or she is not dead as well.
And of course the user doesn't know/see if he or she is using it because they are dead.

The answer to the riddle is a coffin. The person who makes the coffin (the carpenter or manufacturer) does not need it for themselves, as they are alive. The person who buys it (usually a family member) does so for someone else who has passed away and has no use for it. Finally, the person who uses it (the deceased) cannot see or feel it.
