Bathroom step stools are designed to help people reach items that are placed high up, such as shelves or cabinets. While these stools can be very useful, they can also pose a safety hazard if they are not designed properly or if they lack certain safety features.

Here are some important safety features to look for when choosing a bathroom step stool:
1. Non-Slip Surface: A bathroom step stool should have a non-slip surface on both the top and bottom to prevent slips and falls. The top surface should be made of a non-slip material, such as rubber or textured plastic, to provide grip and prevent the user's feet from sliding off the stool.

2. Sturdy Construction: The stool should be sturdy and stable enough to support the weight of the user without tipping over. Look for a stool with a wide base or legs that flare out for added stability.

3. Handrail: Some bathroom step stools come with a handrail or handle that the user can hold onto for added support and balance. This can be especially helpful for older adults or individuals with mobility issues.

4. Locking Mechanism: If the stool is foldable or collapsible, it should have a locking mechanism to keep it securely in place when in use. This will prevent the stool from collapsing or folding unexpectedly and causing injury.

5. Weight Limit: Make sure to check the weight limit of the stool and ensure that it can support the weight of the intended user.

Having these safety features in a bathroom step stool can help prevent accidents and injuries, and give users peace of mind when using the stool to reach high items.
