"2) A rug or mat under the trainer to cut down on noise. If you get used to using a trainer you wll prob wind up with a fluid one. Less noise."
Even if the noise is a non-issue, an old rug or towel will be better to catch the sweat droplets than your carpet.
Actually, I picked up an old Schwinn Suburban step thru frame from GoodWill for $15 I use on my trainer. I am way to old and fat to try to climb up on a bike on a front lift and trainer.
