These non-weighted foam forms are made of molded polyurethane foam with permanent polyester fabric covers. They are recommended for right after surgery when a silicone form is too heavy. These forms can be worn while sleeping to add comfortable support and are contoured to fit snugly against the body with a security tab to help anchor the forms along a bra, nightgown or camisole band. Beige only in 16 bra sizes, 32A-42D left and right.
