Construction and Portability

Soft and hard-shell chambers create different installation and operating commitments. Compare the room, user flow and ownership requirements first; use HBOT vs mHBOT when you need the terminology and pressure overview.

Soft chambers use medical-grade TPU with airtight, triple-sealed zippers over an internal support frame. They are light, foldable and installed by one person in a spare room — and folded away when not in use. The COSL15 and COSE15 are good examples of the soft family.

Hard-shell chambers are rigid carbon-steel or stainless-steel chambers on a wheeled base, professionally positioned in a fixed location. They feel like a permanent installation because they are one. The COHT20 single-person and COHB20 multiplace systems represent the hard-shell family.

Soft chambers typically run at 1.3–1.5 ATA, though professional portable models like the COSL20 reach 2.0 ATA. They hold one user, or two in double and wheelchair models . Hard-shell systems reach 2.0 ATA and, in multiplace form , treat up to five users at once — the key to throughput in a busy facility. If pressure terms are new to you, see ATA pressure explained .

Choose a soft chamber if you want home wellness, recovery or a flexible, budget-conscious system you can install yourself — start with chambers for the home . Choose hard-shell if you are equipping a clinic or facility and need clinic-grade 2.0 ATA pressure or multi-user capacity.
