Verified PurchaseUpdate: After two

Verified Purchase
Update: After two weeks of use, I still like this Sivan balance ball chair with no back. I solved the sore bottom problem by sitting a little further back on the ball. Much more comfortable. I still have had no incidents of feeling like I am going to fall off. I keep all 4 wheels locked, and the surface of the ball is not slippery. I have the ball filled to 65 psi and it does not seem to have lost any air in two weeks.

After reading many reviews, I selected this Sivan balance ball chair with no back. The company was very responsive to my request for a piece missing from the box with a broken seal. I suspect I got a chair that someone else returned, but the Sell Below Cost company offered the best price I found, were quickly and accurately responsive, and included an apology for the missing piece and an offer to help if there were any more problems. Love doing business with a company with that type of service and attitude. The original order was received quickly, and the replacement part followed quickly within a couple of days while the ball was sitting at room temp and getting the first fill of air. I love that all 4 wheels lock. At my age, it is critical to avoid falls, and I think 4 locks helps. I have not had any trouble with falling off or feeling like I might fall off. With the wheels locked, I am able to move around a little and reach where I need to reach with no extraordinary efforts. Initially, I did not put enough air in the ball. The low air was perfect for my height to the ground with 90 degree angles at the knees, but I felt too low for my office desk and felt none of the movement advantages others described. I added air from a compressor and used 65psi as my cutoff. The ball almost doubled in size! I like the way it sits much better, but it is too high and I use a stool or I exercise calves while not using a stool. I choose to use the ball higher because I feel the "balancing" effect is there with the extra air, but not with the lower air. The whole assembled chair is also light enough for me to pick it up and put it outdoors on my deck, my favorite place to work! My only complaint is that my 'bottom' gets sore, kind of like riding a new bicycle seat but more spread out. The soreness is only after I have been sitting awhile, and does not continue after I get up and move around. I am hoping the soreness goes away completely as I use the chair more often and for longer periods. Plus, the pain forces me to get up and take a break, which is a huge plus for circulation. I tend to forget the lengthy time stretch I am sitting, so forced breaks are a plus. I am taking the advice of others and attempting to gradually extend time on the ball. I have had no more back pain than I have in regular office chairs. I recommend this Sivan balance ball and chair base for economy, quality, and the exercise-while-sitting purposes for which it is intended. I doubt I will ever do other exercises on it, because of the chance of falling. I hope I can benefit from the balancing movements others have described while using it as a desk-work chair.

Xác nhận mua hàngCập Nhật: Sau hai tuần của việc sử dụng, tôi vẫn thích chiếc ghế thủy cân bằng bóng này với không trở lại. Tôi giải quyết vấn đề đau dưới bằng cách ngồi một chút xa hơn trở lại vào bóng. Thoải mái hơn nhiều. Tôi vẫn còn có không có sự cố của cảm giác như tôi sẽ rơi ra. Tôi giữ tất cả các bánh xe 4 khóa, và bề mặt bóng không phải là trơn. Tôi có quả bóng đầy 65 psi và nó không có vẻ đã mất bất kỳ không khí trong hai tuần.After reading many reviews, I selected this Sivan balance ball chair with no back.
