Correct a sunken chest at home, without surgery
FormaChest is a vacuum bell system for pectus excavatum that uses gentle, controlled suction to lift the caved-in area of the chest outward, a little more each day. Worn on a simple daily routine, that steady lift works with your cartilage while it is still flexible, which is exactly how conservative pectus correction is meant to work.
Why people choose it over surgery
The Nuss procedure can run past $40,000, means metal bars in your chest for two to three years, and weeks of recovery. FormaChest is a one-time purchase you run yourself, at home, on your own schedule. No hospital, no anesthesia, no downtime. For most people with mild to moderate pectus, it is the first thing to try long before anything invasive is on the table.
Backed by real clinical research
Vacuum bell therapy has been studied for over two decades. In the largest long-term cohort (Basel), roughly 80% of consistent users saw meaningful improvement, with the strongest results in younger patients whose cartilage is most pliable. Work from Klobe, Haecker, Haje and Scaife all points the same way: start early, stay consistent, and the chest responds.
How it works
Place the bell over the deepest point of the chest and pump out the air with the hand pump. The vacuum draws the sternum toward its natural position and holds it there. You control the pressure the whole time, so every session is exactly as strong as is comfortable. Twenty quiet minutes a day is all the routine asks.
Made to be worn every day
Soft, platinum grade silicone seals cleanly against the skin and stays comfortable through a full session. It does not pinch, slip or irritate, so daily use never becomes a chore. Nine sizes, from XXS to XL for men and S to L for women, each shaped to seat precisely over your chest.
Designed by someone who lived it
FormaChest was built by a founder who dealt with pectus excavatum himself, so every detail, from the seal to the pump to the fit, is built around what daily correction actually feels like. This is the tool he wished existed.
