The top shelf: This is typically the most accessible for adults and allows for easy reach without bending or stretching.<br /><br />2. Right in the middle at eye level: This is also a good option as it is at a comfortable height for most adults and allows for easy access to items.<br /><br />3. Right below eye level: This is another good option as it is at a comfortable height for most adults and allows for easy access to items.<br /><br />The bottom two shelves are generally not the best options for adults as they can be difficult to reach and may require bending or stretching.
