Soft-Shell vs. Hard-Shell Chambers
Soft-shell and hard-shell hyperbaric chambers are the two main chamber styles: flexible fabric enclosures rated for mild pressure (up to about 1.5 ATA), and rigid steel or acrylic enclosures built for higher, repeated-use pressures (often up to about 2.0 ATA).
Quick answer
- Soft-shell chambers are flexible, portable, and operate up to about 1.5 ATA.
- Hard-shell chambers are rigid, reach higher pressures (often up to ~2.0 ATA), and suit clinical, high-throughput use.
- Home users usually favor soft-shell; clinics usually favor hard-shell.
Hyperbaric chambers come in two broad styles: flexible soft-shell chambers and rigid hard-shell chambers. The right choice depends on the pressure range you want and where the chamber will be used.
Soft-shell chambers
Soft-shell chambers use a flexible, sealed fabric enclosure with a zippered entry. They are lighter, more portable, and typically operate up to about 1.5 ATA, which places them in the mild range.
Because they are easier to move and set up, soft-shell chambers are popular for home users and smaller studios. Our Horizon soft-shell chamber is designed for this kind of use.
Hard-shell chambers
Hard-shell chambers use a rigid frame, usually steel or acrylic, with a sealed door. They can support higher pressures — often up to 2.0 ATA — and are built for repeated daily use.
These chambers suit professional, higher-throughput settings such as clinics. Our Summit clinical hard-shell chamber is built for that environment.
Choosing between them
Think about pressure range, available space, how often the chamber will run, and who will operate it. A home user prioritizing comfort and portability and a clinic running back-to-back sessions have very different needs.
Whatever you choose, the equipment must be installed and operated per the manufacturer's instructions and any local code requirements.

Common questions
Which is better, a soft-shell or hard-shell chamber?
Neither is universally better — it depends on your goals, available space, and how often the chamber will run. Home users who value comfort and portability often choose soft-shell, while clinics running back-to-back sessions often choose hard-shell.
What pressure can a soft-shell chamber reach?
Soft-shell chambers typically operate up to about 1.5 ATA, which is the mild range. Hard-shell chambers can reach higher pressures, often up to about 2.0 ATA.
