The opening comes before the storage volume
A boot can have enough internal volume and still be awkward to load through its opening. Measure the narrowest usable part of the opening and compare it with the chair in the configuration you will actually load. Include protruding parts that remain attached.
For an illustrative example, an item presented 65 cm wide will not pass straight through a 62 cm clear opening in that orientation. Turning it may change the result, but also changes the space and handling needed. These are example dimensions, not a vehicle compatibility claim.
Follow the lift over the lip
Look at the path from the ground to the final storage position. The boot lip can require an additional lift before the item reaches the floor. A deep space may then require reaching further inside. The lowest loading floor is not automatically the best arrangement for every person or loading aid.
Four measurements with different jobs
| Measurement | What it describes |
|---|---|
| Clear opening | The space the equipment must pass through. |
| Lip height | The edge it must clear before reaching the floor. |
| Floor height from ground | The height involved in the loading method. |
| Usable depth | How far equipment must move once inside. |
Test with the rest of the journey packed
Bring the equipment that normally travels with the chair: removed battery, cushion, bags and any loading aid. Check whether the boot closes with everything in its intended position and whether the first item needed on arrival remains reachable.
Have the actual loading method demonstrated in a suitable setting. If a hoist or other adaptation is involved, use the installer’s compatibility assessment. Finish by unloading: a successful lift into the car does not establish that removing the equipment is equally manageable.
