The key aspects of a custom footstool revolve around tailoring it to meet specific aesthetic, functional, and ergonomic needs. Here are the main aspects to consider:

1. Dimensions
Height, width, and depth based on the user’s preferences and how it will be used (e.g., footrest, extra seating, or storage).

Should match the proportions of the furniture it will accompany (e.g., a sofa or chair).

2. Functionality
Standard footrest or multipurpose (e.g., storage ottoman, tray table, or convertible seating).

Mobility: Fixed legs or casters for easier movement.

Weight capacity if it’s to be used for seating.

3. Materials
Frame: Wood, metal, or composite based on durability and design preference.

Upholstery: Leather, fabric, vinyl, or other materials tailored to the room’s style and durability requirements.

Padding: Foam density affects comfort and longevity.

4. Style & Design
Matches the interior decor (modern, traditional, rustic, etc.).

Custom fabric patterns, tufting, piping, or nailhead trim for aesthetics.

Shape options: rectangular, square, round, or custom forms.

5. Finish & Color
Choice of stain or paint for wood elements.

Upholstery color and texture to coordinate with the room.

6. Ergonomics
Designed for proper leg support (ideal footstool height is typically 10–18 inches from the ground, depending on the seat it accompanies).

Sufficient surface area for comfort without taking up excess space.

7. Craftsmanship & Durability
Quality of joinery, stitching, and upholstery.

Long-term durability, especially if it sees frequent use.
