1) Start with body size: seat width & weight capacity

Your body size is one of the most important factors:

If you have a standard or petite body type
→ you usually don’t need an extra-wide seat.
If you have a larger build (broader hips/shoulders or higher body weight)
→ you’ll be more comfortable and secure in a chair with more seat width and higher weight capacity.

With OAS models:

OAS Air Pro – best for standard or petite body types

Seat width: 16.5"
Weight capacity: 260 lbs

OAS Air Ultra – for larger builds who still want a compact, foldable chair

Seat width: about 17.8"
Weight capacity: 300 lbs

OAS Cruise Pro – roomiest option for larger users

Seat width: about 17.8"
Weight capacity: 350 lbs

If you are close to or above 260 lbs, or you feel tight in a narrow seat, Air Ultra or Cruise Pro will usually feel better. Otherwise choose Air Pro

2) Think about where you’ll use it most

Different models shine in different environments:

Mostly indoors, tight spaces, apartments, narrow hallways
→ You want something compact with a small turning radius.
→ OAS Air Pro is usually the easiest for narrow doors, small bathrooms and elevators.

→ OAS Air Ultra is still quite compact, but a bit wider.

Mix of indoor + outdoor use (sidewalks, parks, shops)
→ All three models can handle mixed daily use.
→ Choose based on body size + how much stability/space you want:
Standard/petite → Air Pro
Larger build → Air Ultra or Cruise Pro
More outdoor cruising, rougher paths, neighborhood rides
→ You’ll appreciate a more robust frame and bigger wheels.
→ OAS Cruise Pro with 12.6" rear wheels offers the most planted, stable ride outdoors.

3) Consider who will lift the chair (and how often)

Ask yourself:

“Who is going to fold and lift this into a car trunk?”

If you want to fold and lift it mostly by yourself
→ OAS Air Pro is our lightest（33 lbs） and most compact option – usually the easiest for one person to manage.
If you have a larger build and can handle a bit more weight
→ OAS Air Ultra is still foldable and trunk-friendly, just slightly heavier and wider than Air Pro.
If you have a caregiver to help or use a ramp/lift
→ You can consider OAS Cruise Pro for maximum space and stability, even though it’s heavier.

All three models are foldable and can go into many car trunks, but Air Pro is the most “suitcase-like” in daily use.
