Trideer Exercise Ball Chair – Yoga Ball Chair for Office, Pregnancy & Home

This yoga ball is great. My wife found it hard to blow up, but the two of us got it blown up. We use it for balance exercises and wall squats.

Great quality, and a good value. I ordered according to the size guide on the Amazon page for this item, but when I tried to use the ball it was too large. I emailed Trideer customer service explaining my problem and received a reply the next day. We went through a couple of attempts to see if the ball would work for me at different inflation levels. When it became clear that it was just too big Trideer promptly sent me the next size down, which turned out to be the perfect fit for my needs.

I've had this for a couple of years; when I first got it, put it together and used it for a week or two, and then put it aside and never got back to it until recently. The ball itself is fine; naturally, it does lose air over time. When I returned to using it recently, I had to put more air in. The plugs are pretty hard (very hard, perhaps?) to get out... it's a very good thing I didn't lose the little tool. The weakest part of this is the inflator - I have had the hose pop out at the hose pump by just using it. The other end (that one puts into the ball or ring) is two-parted, and came apart, losing air. The pumping up system could use to be improved. Except for the inflation thing, the ball seems pretty solid and sturdy and does its job. I tend to set too far forward on the ball (maybe I'm afraid of going over backwards), so it feels like it's tipping me forward a lot... I usually have to adjust 2-3 times until I get it right. I assume it's doing what it says... after using it, I can feel my core muscles.my core muscles are

Love the quality and purple color

The ball and base were super easy to inflate with the included pump. It came with a few extra plugs in case the other ones get lost. The material feels very thick and sturdy, and the aqua color is bright and happy. I have mild scoliosis and a stenosis at L5 which is just above the tail bone. Every now and then it will get inflamed and cause lower back pain. When I tell you the MOMENT I sat on this ball the back pain disappeared, I am not exaggerating. I am going to get another one so I can have them in both my home and work offices. I am just over 5'5" so got the 65 cm ball. It feels ergonomic to sit on, but I am wondering if the taller one would have been slightly better to reach the keyboard on top of the desk. I'll probably wait a few days to inflate it a little more (per the instructions to give it time to stretch) and see how comfortable I am with the height before ordering another one. Edit: It is now fully inflated, and it is the perfect size for my height with a keyboard that sits at 29-30"

Really great quality ball. I’m excited to use it to build up my core due to a weak pelvic floor and help with my degenerative disc disease, which makes it hard to sit while working. I give it three stars for a perfect ball. I give it only three stars because the base is way too big even after following the guidelines of filling it to 80% and then leaving it for a day or two and filling it more to make the ball bigger. Even when I sit on it, flattening it a bit, it still rolls a ton. The ring is just way too big for my liking. I have the size large ball and I hate how much it rolls. I’m gonna buy a plastic ball base instead. I also really could use the extra 2-3 inches in height that you get with a hard base since I am 5 feet tall and my desk at its lowest setting of 28 inches, with a tray that drops down even lower for a keyboard, is still too high. I hope it works out. If not, I at least have it for exercise.

I pulled it out of the box and gave the included little hand pump a try. Holy cow. That was a workout! Both arms were tired and if you stop, the air back- flows. No thanks. I'll save that for inflating balloons. I broke out an air compressor and filled the ball until it looked taught, but not over-filled. I let it sit overnight. The next day I gave it a sit and felt entirely too low to the ground. I put a little more air in it, but was worried about how much air it could take. I have it another sit and it felt much better... so I worked a full day on it. I had to keep reminding myself to straighten up my back. It takes some getting used to. You certainly can't whirl around to see behind you, like you would in a typical office chair... so when I heard my dog outside the door, I had to twist and crane my neck. LOL. After a day on it I decided it still felt a little low for me. I'm 5'6" tall, with a 28.5" desk, so I got the Large 65cm ball as suggested. I broke down and grabbed the instructions, to make sure I didn't over-inflate it. I measured from the floor, up the wall 65cm, made a pencil mark, then took a straight edge and held it out... I definitely had more room to go to inflate it... and I did! It's at about 63cm now, because I don't like to press my luck. I'm up at a good height now, comfortably resting my forearms on the desk, the keyboard is comfortable and I can still put both feet firmly on the floor. I put the ring under the bottom because I don't want to accidentally bust my ashtabula on this thing. It's comfortable. I can work a very full 12 hr day on it. I push it up so 40% of it is under the desk, and I approach it from the side and swing my leg over it like a horse, then plop my arse down. It's sturdy, has a little bouncy bounce to it, but only when you shift your weight or adjust your legs. It retains air well, so far. Another nice thing is that you can grab ahold of the front of your desk, lift your feet up in front of you, and roll forward while arching your back, until your basically laying on your back, over the ball. It gives a great stretch. Overall, I give it ⭐️⭐️⭐️⭐️⭐️.

Offered in three size ranges. I wax not expecting a ring base to stabilize the ball during exercise and for storage. The ball is dark space gray in color. No skimping on the quality and materials either.

I use this as a seat at my desk. It has caused me to sit correctly, plus it is just SO easy to exercise your hips and core whilst working. I am sure it can be used for many other exercises, but haven’t discovered them yet. Wouldn’t be without it!

Der Ball wird mit einer Pumpe geliefert - man muss zwar erst rausfinden, welches der beiden Pumpenenden hier Luft saugt und welche bläst, aber das hat man schnell rausgefunden. Der Ball hält die Luft sehr gut drin und der Standring ist ideal für die Aufbewahrung. Rundum: Klasse Gymnastikball.

It's pity there is only black colour, so I had to order another one from Amazon US.

Sit on it daily. It does encourage you to slouch to focus on not slouching.

Der Ball hat unschöne Falten. Er ist seit Donnerstag aufgepumpt und würde nochmal nachgefüllt. Aber die Falten gehen nicht weg. Der Äquator ist weder Beim Ball als auch bei dem Ring nicht schön verarbeitet. Widerstandsbänder wurden keine mitgeliefert.
