ᐅ How can I build an IKEA Besta unit into a multifunctional bench with storage?

Hello everyone,

I am planning to modify the IKEA Besta system to create a multifunctional bench with built-in storage. My idea is to combine the modules in a way that makes them comfortable for sitting while also providing storage space in the compartments for items like cushions, blankets, or other household goods.

I am particularly interested in the following points:
- What dimensions are recommended for a comfortable seat height when using Besta units for this purpose?
- Are there proven ways to add a padded seat on top without compromising the stability of the modules?
- How can the doors or flaps be modified so they remain easy to use despite the bench function?
- What are common pitfalls when carrying out such a conversion?

I look forward to your experiences and tips, as I want to build a durable, functional, and aesthetically pleasing piece of furniture that offers more than just storage.

Thanks in advance!

That’s a very good approach. A comfortable standard seat height is about 45 cm (18 inches), which you can ideally achieve by fitting Besta units with suitable legs or bases to reach this height.

I recommend using a custom foam cushion covered with durable fabric or faux leather. These should be attached with Velcro or other removable fasteners so the padding can be easily removed when needed and stays securely in place.

How can the doors or flaps be modified so they remain practical even when used as a bench?

It’s worth choosing doors with soft-close hinges. Also, replacing solid doors with flaps or drawers can be useful, as these are often easier to access while sitting on the bench. Make sure the hinges are strong enough to handle the weight and use involved in sitting.

Common pitfalls usually include:
- Lack of reinforcement of the units to support seating loads
- Insufficient cushion thickness for comfort
- Doors that are too tight or inconvenient to open

I hope this helps! If you have more specific questions, feel free to ask.

A seat height of about 44 to 47 cm (17 to 18.5 inches) is ergonomically ideal. Since the standard Besta cabinet is approximately 38 cm (15 inches) high, I recommend combining it with feet or a plinth of 6 to 9 cm (2.5 to 3.5 inches) in height.

Use high-density foam with a thickness of at least 4 cm (1.5 inches) and a fabric cover with some friction. Secure the padding with Velcro straps or tension bands on top to prevent slipping. Alternatively, a plywood sheet can be placed on the Besta cabinet as a base for better load distribution.

Drawers often prove more practical than doors here, as they are easier to open when sitting on the bench and accessing storage. Soft-close hinges or dampening hardware also improve usability.

What are common pitfalls when converting like this?

- Insufficient reinforcement of the cabinets under permanent load
- Foam that is too thin and uncomfortable
- Inconvenient access to the storage space

For a durable piece of furniture, I recommend connecting the modules on a stable base to prevent tipping.

This should serve as a structured guide.

I’m happy to provide you with a step-by-step guide for implementing your project, based on my experience with the Besta system:

1. Planning & Measurements:
- Take precise room measurements and measure the seat height of the modules.
- For comfortable seating, aim for a final height of 45-46 cm (18-18 inches).

2. Selecting Modules:
- Use 2-3 Besta cabinets side by side as the base.
- Consider whether you prefer drawers instead of doors – often better ergonomically.

3. Increasing Stability:
- Connect the modules with brackets or screws to create a solid unit.
- Optionally reinforce the back panel or stabilize it with wooden strips.

4. Making Seat Cushions:
- Obtain foam with about 5 cm (2 inches) thickness and a suitable fabric cover.
- Use a thin, sturdy wooden board as a support on top of the Besta cabinets.
- Fix the cushion and support board together with Velcro to prevent slipping during use.

5. Adjusting Doors / Flaps:
- Opening aids such as push-to-open or press-to-open mechanisms make access easier.
- Ensure that sitting on the unit does not deform any flaps.

6. Avoid Common Mistakes:
- Not connecting the cabinets leads to instability.
- Insufficient padding reduces seating comfort.
- Improper opening mechanisms make access to storage difficult.

In summary: Ensure a solid connection between the modules, a comfortable and secure seating surface, and practical access to storage. Keeping these points in mind will give you a stylish, comfortable, and multifunctional bench.
