FYI the ball is NOT too small! It is as advertised, and will fill the cover. As it says above, the ball feels full when it is not fully inflated - just keep pumping. And as silly as you feel using the little plastic foot pump they send, it works the best. Other pumps react to the "full" feeling and get too tight to pump, or let air escape. The foot pump has a one-way valve that traps the air inside, and does not stop working. Handy tip - I filled the ball to the "full" feeling, then let it sit overnight before I finished pumping til it filled the cover. That worked well. ### ⭐⭐⭐⭐⭐ Great buy! *by L***A on Reviewed in the United States on April 27, 2020* Before purchase, I saw that some other reviews mentioned this ball was difficult to blow up. Here's what I did: put the ball in the cover, making sure the nozzle and zipper are aligned. Then, use the wider air spout to blow up the ball about 60%, then switch to the smaller spout and continue to blow up the ball til it reaches 90%, or until it feels tight. Plug the nozzle and leave overnight, or at least 6-8 hours. This will give the ball an initial stretch. After waiting, use the tool to remove the plug, and deflate the ball back to 50-60%. Then, re-inflate, this time going to 100% and plug the nozzle again. Be careful not inflate the ball too much, or you may not be able to zip the cover closed.I did inflate mine too much, got impatient with deflating it, and ended up breaking the zipper. Since I wouldn't be able to zip it up, I added some bubble wrap (fabric would work too) I had around between the zipper and the ball since I wanted to protect the ball from the zipper teeth.I like the ball and the cover. It is working well as on office chair replacement. I'm 5’11”, kinda on the border between a 65cm and 75cm size from what I've read. Now that I've tried the 65, I wish this was available in a bigger size. Overall, I'd recommend this purchase. It's a great price too! ### ⭐⭐ Ehhhh not so great *by B***L on Reviewed in the United States on September 13, 2019* I actually love this... the cover is kind of felt- super great color and fabric. BUT the ball is way too small for the case they sent. The pump they sent is horrible but on par for any pump sent with a blow up thing. I used an electric pump that we use at the beach for floaties. Still leaves a whole lot of space between the ball and the case. I cant use it at my desk because its way too small. I sent a message to the company to see if I got a ball that was the wrong size or something but they never replied. I should have returned it but I was waiting to hear back and then we had a hurricane and the box got thrown away. So I decided I would just try to get another ball that is bigger and maybe fits the cover because that part is really nice. But overall...wouldn't purchase again. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/148839503-stability-ball-chair-for-office-with-cover-65-cm-sitting](https://www.desertcart.tn/products/148839503-stability-ball-chair-for-office-with-cover-65-cm-sitting) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-16*
