Overview
Black Mountain Products' peanut-shaped stability ball measures about 14 inches tall by 32 inches wide, rated to a 2000 lb static weight capacity, and ships with a foot pump and plug puller for inflation.
The elongated peanut shape keeps it from rolling away the way a round stability ball does, which is why reviewers use it for labor support during childbirth, infant strengthening exercises, and stationary PT and core work. A couple of buyers found the included foot pump flimsy, and one received a ball that inflated lopsided rather than evenly on both sides.

Who it's for
Good for physical therapy patients working on core and balance, parents using it for infant strengthening or labor support, and general home stretching. Less suited to clinical PT exercises that require guaranteed left-right symmetry, given one report of an unevenly inflated unit.
