What to know before buying

Listing details to confirm

The title and size details give a 120 cm diameter, while the product description gives 1200mm (47¼"). These are broadly consistent, but the title's 47.5-inch conversion differs slightly from the description's 47¼-inch figure. The listed packaged dimensions of 32 x 23 x 16 cm are not the inflated ball dimensions. The maximum user weight and burst-resistance wording are manufacturer claims, not independently verified here. The inflator is sold separately.

Who is it for?

A good fit for

Buyers seeking a large ball described for therapy, sports, gymnastics or aerobic exercise.
People looking for a ball that can also be used as a sitting ball, subject to checking its diameter against their space and needs.

Less suited to

Buyers who need an inflator included in the purchase.
Anyone whose space or intended use calls for a smaller ball.

Aggregate ratings are positive overall, with a majority in the five-star category, but some lower-star ratings mean experiences are not uniformly favourable. The evidence contains no written review summaries, so it cannot show what customers liked or disliked. For a large ball where fit and intended use matter, confirm the diameter and stated weight limit against your requirements rather than treating the ratings as proof of performance.

Frequently asked questions

What diameter is this gym ball?

The description says the ball is supplied ready to inflate and explicitly states that the inflator is sold separately.

What is the stated maximum user weight?

The product description states a maximum user weight limit of 300kg (47st). This is a manufacturer listing claim.

What can the ball be used for?

The listing describes uses including therapy, sports, gymnastics, games, toning, aerobic exercise and sitting.
