I am using this net in a 12x16 room with hardwood floors. It was an experiment, but I figured it was my best winter option in a Wisconsin climate. I set the net up with relatively low tension and tilted it backwards to limit the rebound distance. The results were even better than I had hoped! After a few sessions I was managing long rallies. I was even using the net to begin a switch to a two-handed backhand, and was successful after a few minutes! Note that I am a 73 year-old male who took up tennis as an adult, and am still improving!
