FormaChest vs Pectushealing: An Honest Vacuum Bell Comparison (2026)

Last verified: August 2026. Prices and stock change. We date this page so you know how fresh it is.

Short answer: FormaChest and Pectushealing both sell vacuum bells built on the same clinical method Dr. Eckart Klobe pioneered in 2005. Pectushealing is a specialist device maker with the widest size range and a 10-year device warranty. FormaChest is a guided correction system (the bell plus a protocol, a fit assessment, and ongoing support) at a lower entry price, backed by a 90-day money-back guarantee. If you want the largest catalogue of sizes or a decade-long warranty on the hardware, look hard at Pectushealing. If you want a coached, lower-cost path with an outcome-based guarantee, especially for a teenager where consistency is the whole game, that's what FormaChest is built for.

The method is the same, so what actually differs?

Both companies sell the same category of device: a vacuum bell that uses gentle suction to lift the sternum, the non-surgical approach Dr. Eckart Klobe developed in 2005 and that has now seen roughly 20 years of clinical use. Vacuum-bell therapy is offered at major children's hospitals, including Cincinnati Children's. Neither brand invented the science, and it would be dishonest to pretend one has a secret mechanism the other doesn't. The device does the lifting in both cases.

What differs is everything around the device: price, what's included, the guarantee, and whether you're handed a piece of hardware or walked through a protocol. For a therapy whose results depend almost entirely on consistent daily use, that "everything around the device" is not a footnote. In one published cohort, structured support raised adherence from 58% to 83% (Haje 2021), and adherence is the single biggest lever on whether a vacuum bell works for you.

Price: where FormaChest is clearly lower

A FormaChest vacuum bell is $360 for men's sizes and $390 for women's, with free worldwide shipping and nothing else to buy to start.

Pectushealing's standard bells run $465 to $635 depending on size (women's design $495; custom bells up to about $1,200), also with free worldwide shipping. Their hand pump ($95) and pressure gauge ($110) are listed as separate purchases. A bell needs a pump to function, so the realistic starting cost for a working Pectushealing setup is meaningfully above the sticker on the bell alone.

That makes FormaChest the lower-cost entry point among active, warranty-backed manufacturers, not by cutting the device, but by shipping the pump integrated and not up-selling accessories to make the thing work.

What's included: hardware vs a system

This is the real philosophical split.

Pectushealing sells the device. You choose a size (they offer a paid size consultation for $25 if you're unsure), it arrives, and you run the protocol yourself. Their strength is optionality: eight sizes plus custom means almost any chest can be fitted, and the 10-year warranty on the hardware is genuinely generous.

FormaChest sells a correction system. The bell ships with a protocol guide, a fit assessment to get your size right before you buy, and ongoing support, plus the option to add the chest brace and post-therapy gel as a Complete System ($461.40 men's / $491.40 women's) if you want the full routine in one order. The bet is simple: for most people, and especially for teenagers, the thing that fails isn't the device. It's stopping after three weeks. The system exists to keep you consistent, because consistency is what the research rewards.

The guarantee: outcome vs durability

These sound similar but protect you against different things.

• FormaChest: 90-day money-back guarantee. This is outcome risk-reversal. If it isn't working for you, you get your money back. A company only offers this if it's confident in real-world results.
• Pectushealing: 10-year warranty. This is durability. It protects the physical device against failure over a decade. Valuable, but it doesn't refund you if the therapy isn't right for you.

Which matters more depends on what you're worried about: the device breaking (Pectushealing has you covered longer) or spending $400+ on something that doesn't fit your case (FormaChest carries that risk for you).

Does the vacuum bell actually work?

For the right candidate, the evidence is real and it's the same evidence for both brands. Across peer-reviewed research the therapy has been studied in more than 1,000 patients; a Swiss (Basel) cohort of ~140 showed significant improvement in roughly 80% of studied patients. It works best on younger, more flexible chests and with consistent daily use; published adult timelines commonly run 12–24 months, and results vary from person to person. It is not a fit for every case. Severe, rigid adult chests respond least, and inconsistent use is the most common reason it fails. Anyone considering it should confirm their diagnosis and candidacy with a physician.

Which one should you choose?

Choose Pectushealing if you need a very specific centimeter size or the widest possible size range, you want a decade-long warranty on the hardware, and you're comfortable self-managing the protocol without built-in coaching.

Choose FormaChest if you want a guided system rather than a bare device, a lower entry price, an outcome-based 90-day money-back guarantee, and, especially for a teen or a child where a parent is steering the routine, structure and support to keep the therapy consistent long enough to work.

Both are legitimate Klobe-method vacuum bells from real companies. This page is published by FormaChest, and we've tried to represent Pectushealing accurately from their own site; if anything here is out of date, tell us and we'll fix it.

Frequently asked questions

How does FormaChest compare to Pectushealing?

Both sell Klobe-method vacuum bells. Pectushealing offers the widest size range (8 sizes plus custom) and a 10-year device warranty, at $465–$635 with the pump sold separately. FormaChest is a guided system (bell plus protocol, fit assessment, and support) at $360 (men) / $390 (women) with the pump integrated and a 90-day money-back guarantee.

Is FormaChest cheaper than Pectushealing?

Yes. FormaChest's bell is $360–$390 with free shipping and the pump included. Pectushealing's standard bells start at $465 with the hand pump ($95) listed separately, so a working setup costs more.

Do both actually work for pectus excavatum?

They use the same clinically studied method. Across peer-reviewed research the therapy has been studied in 1,000+ patients, with ~80% of a studied Basel cohort showing significant improvement. It works best on flexible chests with consistent daily use; results vary and it isn't right for every case. Confirm candidacy with a physician.

Which is better for a teenager?

Younger, more flexible chests tend to respond best, so the teen years are a strong window, but only if the routine stays consistent. FormaChest's guided system is built around that, and for anyone under 18 the right path is a parent or guardian leading the process. Get the free parent assessment →

What if it doesn't work for me?

FormaChest offers a 90-day money-back guarantee, so the outcome risk sits with us, not you. Pectushealing offers a 10-year warranty covering the device itself.
