Sitting vs Lying Hyperbaric Chamber: Which Is Easier to Use at Home?
Is a sitting or lying hyperbaric chamber easier to use at home? For most people, a sitting chamber is easier: you walk in, sit on a chair and stand up again. Choose a lying chamber only if everyone using it can get up off the floor easily.

Quick answer
- How easily you get in and out decides how often a chamber gets used, so pick the position before the pressure.
- Sitting up costs you no pressure: soft sitting chambers run 1.2 to 1.5 ATA, and hard sitting chambers go up to 2.0 ATA.
- Sitting chambers need less floor length but more height. Our soft sitting and wheelchair models stand about 68 to 75 inches tall.
- Wheelchair users need a roll-in chamber, not a standard sitting model.
Sitting vs lying hyperbaric chamber: side by side
A sitting chamber wins on getting in and out and on feeling less closed in. A lying chamber wins on napping, low ceilings and price per inch of interior space. Body position doesn't set the pressure; shell type and ATA do.
| Factor | Sitting chamber | Lying chamber |
|---|---|---|
| Getting in | Walk through a front zip or door and sit down | Kneel or crawl in at floor level |
| Getting out | Stand up from a chair | Roll over and push up off the floor |
| A 60 to 90 minute session | Upright, easy to read or talk; some models recline | Stretch out and rest; reading is awkward |
| Feeling closed in | Headroom above you, windows at eye level | Chamber wall close to your face |
| Floor space | Compact (the MACY-PAN L1 is 60 × 42 in) | Long (the Kingshare sit-or-lie model is about 87 in) |
| Height needed | 68 to 75 in for our soft sitting models | Low (the Kingshare is about 43 in tall) |
| Pressure | 1.2 to 1.5 ATA soft, up to 2.0 ATA hard | Same ranges |
| Price at Selected Comfort | About $5,950 to $13,800 soft; $27,450 to $45,999 hard | About $5,750 to $10,000 soft |

Our hyperbaric chamber cost guide breaks prices down further. In any sitting vs lying hyperbaric chamber decision, the first row is the one that settles it for most of our customers. If anyone in the house hesitates at the idea of getting down to the floor and back up every day, start with the sitting column.
Why getting in and out matters more than pressure
A chamber that's hard to get into stops being used, no matter what pressure it reaches. With a soft lying chamber, you lower yourself to the floor, crawl through a zipper and lie down. At 40 that's nothing. At 75 with a replaced hip, it's why the chamber sits unused.
At Selected Comfort, we help customers choose a chamber around how they'll actually use it every week, and you can compare every sitting, wheelchair and lying model in our hyperbaric chambers collection.
Vineet Arora, founder of Selected Comfort, is firm on this. His advice is that seniors and anyone with stiff knees or hips should buy a sitting or wheelchair-entry chamber rather than a lying soft one. When he hears about regrets, difficulty getting in and out is near the top of the list, along with buying a chamber that's too small and not planning for the noise and heat.
Hard lying chambers have a proper door, but you still climb in and lie down. In a sitting model, entry works like sitting down at a table.
Quick test
Before you buy, have each person who will use the chamber sit on the floor and stand back up without help. If anyone struggles or needs a hand, buy a sitting or wheelchair model.
Comfort over a full session
Sitting is more comfortable if you want to read, talk or work; lying is better if you want to sleep. A typical home session runs about an hour, often longer, and sitting upright lets you shift position as you go.
The OxyRevo Forward90 1.5 ATA comes with an adjustable folding chair, so you can sit up or lean back into a semi-lying position. The hard OxyRevo Space60 can take a reclining folding chair.
If you feel closed in, an upright hyperbaric chamber with windows at face height tends to feel less confining. OxyRevo says the Space60's windows reduce claustrophobia, but that's a manufacturer claim and won't hold for everyone.
OxyRevo Space60 1.5 ATA$42,999 · financing available
Hard sitting chamber with a large front door, big windows and room for a reclining chair.

Watch out
Heat and noise affect both formats. Check whether an air cooler is included, and plan where the compressor will sit, because you'll hear it.
Soft vs hard sitting hyperbaric chambers
For most homes, a 1.3 to 1.5 ATA soft sitting chamber does the job; a hard shell makes sense only if you need 2.0 ATA or a clinic-style build. Once you've decided to sit, shell type is the next choice (our soft vs hard shell guide goes deeper).
| Model | Shell | Pressure | Entry and seating | Price | Best for |
|---|---|---|---|---|---|
| TECNOTU TecnoSit Classic 1.5 ATA | Soft | 1.3 to 1.5 ATA | Sit-in cabin, about 40 lb, 10 L/min concentrator | $5,950 | Lowest-cost way to sit up |
| OxyRevo Forward90 1.4 ATA / 1.5 ATA | Soft | 1.4 standard, adjustable 1.2 to 1.5 | Curved zip, folding chair included, fits an adult and a child | $9,499 / $10,499 | Sitting or semi-reclining |
| MACY-PAN L1 | Soft | 1.3 to 1.5 ATA | Shaped zip, fits a regular chair, 60 × 42 × 68 in | From $10,990 | Smaller rooms |
| TECNOTU TecnoSit Ultra 2.0 ATA | Hard | 1.3 to 2.0 ATA | Steel shell, 550 lb maximum occupant weight | From $27,450 | 2.0 ATA seated, heavier users |
| OxyRevo Space60 1.5 ATA / 2.0 ATA | Hard | 1.5/1.6 working, up to 2.0 | Large front door, about 79 in long | $42,999 / $45,999 | Walk-up door, clinic-style build |

Vineet would only spend $13,000 or more on a hard shell for someone with a specific need for higher pressure, a wish for clinical-style equipment, or a dedicated room and the budget. If you're weighing that step, read our 1.5 vs 2.0 ATA guide, and check the working pressure on the listing, not just the maximum.
TECNOTU TecnoSit Ultra 2.0 ATAFrom $27,450 · financing available
The lowest-cost way to reach 2.0 ATA sitting up, with a 550 lb occupant limit.
View productHyperbaric chambers for wheelchair users
Wheelchair users should buy a roll-in wheelchair chamber, because a standard sitting chamber still means standing up and transferring to a chair. A wheelchair hyperbaric chamber lets you roll straight in.
- The OxyRevo Heal40 ($11,499) has a sloped aluminium base for rolling in, runs at 1.2 to 1.4 ATA and measures 67 × 62 × 75 in inflated.
- The MACY-PAN MC4000 (from $11,500) comes in an N-type door version for wheelchairs and runs at 1.3 or 1.4 ATA. It measures 61 × 59 × 69 in.
- The TECNOTU 1.3 ATA Wheelchair Chamber (from $7,950) has touchscreens inside and out and a 15 L/min concentrator.
MACY-PAN MC4000From $11,500 · financing available

Who should choose sitting, and who should choose lying
Choose sitting if getting down to the floor is hard for anyone in the house; choose lying only if everyone can get up off the floor easily and mainly wants to rest.
Choose a sitting chamber if…
Getting down to the floor is slow, painful or needs help. You want to read, work or talk during sessions. Lying flat in a tube makes you anxious. Your room is short on floor length but has a normal-height ceiling.
Choose a lying chamber if…
Everyone using it can get up off the floor easily. You mainly want to rest or nap. Your ceiling is low, as in a basement or under a sloped roof. You want the most interior space for the lowest price.
For a lying chamber with plenty of room, look at the OxyRevo Apex32. Split household? The TECNOTU 1.5 ATA Recline (from $5,750) allows seated and fully reclined positions, though entry is still low.
OxyRevo Apex32 1.5 ATA$8,499 · financing available
A roomy soft lying chamber for people who can get up off the floor easily and want to nap.
View productHow much space does a sitting hyperbaric chamber need?
Plan for the chamber's footprint plus room for the compressor, concentrator and cooler, and at least 68 to 75 inches of clear height. The L1 needs about 60 × 42 in of floor and 68 in of height. The Heal40 needs 67 × 62 in and stands 75 in tall, so leave headroom.
Before ordering, Vineet asks customers to measure:
- Doorways and hallway turns on the delivery route
- Ceiling height in the room where the chamber will sit
- Stairs or elevator access
- The setup area, including space for the compressor, concentrator and cooler
- Floor loading, which matters for hard shells: the TecnoSit Ultra's steel shell alone weighs 1,322 lb
MACY-PAN L1From $10,990 · financing available
A compact 60 × 42 in footprint that fits a regular chair, for smaller rooms.

Mistakes we see with chamber position
Most regrets come from choosing on price or pressure instead of on how the chamber is entered. These are the ones we hear about most:
Avoid
- Buying lying because it's cheaper, then finding the floor-level entry hard every day
- Measuring floor space but not ceiling height for a sitting or wheelchair model
- Buying a standard sitting chamber for someone who can't safely transfer
- Choosing the biggest pressure number and ignoring how the chamber is entered
The bottom line
If anyone in your home finds the floor hard to get down to, buy a sitting chamber. You lose nothing on pressure, sessions are easier to sit through, and the chamber actually gets used. A soft 1.3 to 1.5 ATA model such as the TecnoSit Classic or Forward90 suits most homes.
Choose a roll-in model like the OxyRevo Heal40 for wheelchair users, and a lying chamber only when everyone can get up off the floor easily and wants to nap. Talk to your doctor before starting, especially with ear, sinus or lung problems.

Frequently asked questions
Is a sitting or lying hyperbaric chamber easier to use at home?
A sitting hyperbaric chamber is easier for most people, because you walk in, sit on a chair and stand up again. A lying chamber means getting down to the floor and back up every session, so it suits people who can do that easily and want to nap.
Can you sit up in a hyperbaric chamber?
Yes. Sitting chambers are built for it, and some models, such as the TECNOTU 1.5 ATA Recline and the OxyRevo Forward90 with its adjustable chair, let you move between sitting and reclining positions during a session.
Is a seated hyperbaric chamber less effective than a lying one?
Body position doesn't change the pressure inside the chamber. Pressure comes from the shell type and the ATA setting, and sitting and lying chambers share the same ranges: 1.2 to 1.5 ATA for soft chambers and up to 2.0 ATA for hard ones.
What is the best sitting hyperbaric chamber for home?
The best sitting hyperbaric chamber for home use is usually a soft model at 1.3 to 1.5 ATA, such as the TECNOTU TecnoSit Classic or OxyRevo Forward90. Choose a hard sitting chamber only if you have a clear reason for 2.0 ATA, a dedicated room and the budget.
What's the best hyperbaric chamber for seniors with limited mobility?
A sitting chamber is best if they can stand and sit safely, or a roll-in wheelchair model such as the OxyRevo Heal40 if they can't. Talk to a doctor first, especially with ear, sinus or lung problems.
How tall is a sitting hyperbaric chamber?
Our soft sitting and wheelchair chambers stand about 68 to 75 inches tall when inflated. The MACY-PAN L1 is 68 inches tall and the OxyRevo Heal40 is 75 inches, so measure your ceiling and leave headroom before you order.
