Balance Ball Standing Desk Chair Stool, Adjustable Jellyfish Chair by Coreseat | Ergonomic Exercise Office Chair That Provides Stability and Core Strength for The Home, Office or Classroom

I loved this seat—really helped me stay alert during long days of editing photos at my computer. Around the same time I raised my desk to make it a standing desk, which also really helped, but I got this chair for when I wanted to take seat. It naturally corrects my posture, and is "fun" to sit or lean on.The chair started leaking about 2.5 months in to owning it, and I have had no reply from the manufacturer (over a week now). I am very disappointed as I don't consider $160 particularly cheap, and it's a total pain in the a** (literally 😂) to have to inflate it once it's sagged down to the hard board beneath the pad. The worst part is that I'm tempted to get another top just because I like it so much, but I will try amazon customer service first.

I’ve only had it for a few days, and already a huge improvement on my back. Like it says, you will be sore at first, but that’s a good sign that the supporting back muscles are getting a workout. I’m actually sleeping through the night, with no wrestless back pain! And, I don’t mind sitting at my desk anymore. It was too tall for my desk- my knees couldn’t cross underneath in the lowest setting, so I grabbed those blocks you use to raise the height of a bed and put them under the legs of my desk. Now it’s perfect. Totally worth the money! Same price as the ergonomic chair I purchased last year with way more versatility and comfort. Also, it naturally encourages me to sit up tall and lengthen my spine, where I find myself hunched, slouched, and compressing my spine in my office chair. If you’re back is getting ruined because you sit for long periods, you are worth the cost of this chair!

LOVE this product! I ordered the Standing Desk Chair for my husband after having such a great experience with the classic Jellyfish Chair, and couldn't be happier. Problem is we have to wrestle it away from our kids who tend to swipe it into their rooms for homework. Great, durable quality; simple, easy-to-assemble design; and seamless height adjustment. Most of all it keeps us moving throughout the day, engages the core, even while being 'stationary' at a desk while working from home. I feel energized rather than sluggish like I do at the end of a day of sitting in a regular office chair. Highly recommend!

I absolutely love this chair. However after about a month it would not hold air. I contacted the seller and a replacement top was sent to me. After a short time, the second started to lose air. My husband decided he was going to try to fix this for me and he did. He said it was losing air around the screw holes where the top is mounted to the bottom stand. He filled the holes with an adhesive sealant. It is holding air and I am very happy with my chair. I have lower back / hip pain when sitting in a regular chair. Using this chair relieves stress on my backside. I really notice a difference.

I have been looking at this chair for a while. I read up on the health benefits and really researched if the cost was worth it. I finally bought one and I already feel a difference in my back and my abs. Since I have to sit all day this is a great way to keep me in shape and also out of pain. It wasn't super hard to put together, but it does feel a bit wobbly and I just feel like the screws didn't fully go in. I also feel like the ball deflates very quickly. Overall a good investment.

I was looking for a chair for my standing desk when I need short breaks from standing, I originally had a drafting table chair and even just for short breaks my back was hurting while sitting in it. I found this chair and have used it for the better part of two weeks now and can report that thus far I have no back pain when sitting/leaning on it when taking breaks from standing. What I also like is you can pump the cushion part up with as much or little air as you like to make it as soft/hard as you want. I would highly recommend this chair as long as you can deal without it having a back rest.Update 8/17/18: I decided to get the seat cover as well. I received the cover today and its great, thank you very much! Fully enjoying the chair!

I ordered my Coreseat Jellyfish chair a year ago (Sept 2, 2018). Was a great chair and worked as advertised until it started leaking about two months ago. Now it won't hold air for more than a few hours and needs to be re-inflated. I've reached out to Coreseat a few times, no response. Checked Amazon messages, no response through them either. I don't know about you, but I expect a $160 chair to function for more than 10 months.

The air does not hold. I have to fill up every 2 days or sooner.Very disappointed.
