The seat cushion is so thin and flimsy it is so uncomfortable. I have been using it for 4 months total, but every single day at least 3-6 hours/day for the past 2 months to nurse my baby and my bottom is always numb. It doesn't help when you're healing from childbirth and your bottom is already sore. It's very narrow and I am 5'3 and 115 lbs. My baby's head always hits the arm rests so I have to hold him in an awkward position.
