The No-Tip Block is constructed with a dense light-weight foam and then topped off by a soft, high quality foam making it sturdy yet comfortable. Its unique design allows weight to be distributed evenly keeping it from tipping like most foam ottomans. Bella is a soft velvet with a soft hand that is easily removable for washing or a quick trip to the dry cleaner.
