Here are some features and characteristics typically associated with hospital step stools:

1. Non-slip Surface: Given the potential hazards in a hospital environment, these stools usually have a non-slip surface on the step to ensure safety.
2. Sturdy Construction: They’re typically made of durable materials and are designed to support a significant amount of weight.
3. Handrails: Some hospital step stools come with handrails to provide additional stability and support, especially if the patient is elderly or has mobility issues.
4. Lightweight and Portable: Many are designed to be easy to move around, and some might even have wheels or casters (which can lock in place for safety).
5. Height: While most are single-step stools, some designs might offer multiple steps to cater to different needs.
6. Easy to Clean: Given the importance of hygiene in a hospital environment, these stools are typically made of materials that are easy to clean and disinfect.
7. Storage-friendly: Some step stools can be folded or nested for easy storage.
8. Durable: They are made to withstand frequent use, so they are typically quite robust.
9. Rubber Feet: To prevent the stool from sliding and to protect the floor from scratches, many step stools come with rubber feet.
