Climbing up and down

The differently-abled child with sufficient motor ability to move without the use of a wheelchair can be made reach higher levels also by the use of special stairs.
These stairs should have steps with a lower height and wide deep tread, to make it easier for a crawling child or one who can use only their arms to climb up. These steps should be fabricated or covered with low impact thermal material, be non slippery, draining and have a certain smoothness.
At the base of the stairs there should be a “transfer platform”, a landing, connected with the stairs, to allow the passage of wheelchairs to the platform itself, to be able to then access the stairs without the need of assistance.

It would be interesting if the transfer platform were composed of at least two floors of different heights, so that its use could be extended. The actual stairs should in any case arrive to the ground.
The stairs should also be fitted with side protections to avoid falls. The presence of handrails, handles, or other types of handholds could be useful at the side of the stairs, at different heights to offer the differently-abled child the possibility to stand up or pull himself up with more ease.
