Hello everyone,

I am planning to add a glass top to an Ikea BESTÅ sideboard. My specific question is: How can I modify or adapt the BESTÅ unit so that a glass top sits securely and stably on it? I am especially interested in tips for attaching the glass, suitable materials for spacers or adhesive pads, and advice on preventing wobbling or slipping.

Additionally, it would be helpful to know whether the original top should be completely removed or if the glass can simply be placed on it. What thickness and type of glass are recommended to ensure the top looks good and is strong enough?

I look forward to your experiences and suggestions, including any simple tips for beginners who don’t have much DIY experience!

A brief addendum regarding common mistakes:

- Avoid using self-adhesive pads that may loosen or discolor over time; instead, use silicone or rubber pads designed for furniture.
- Ensure that the glass top has a slight gap all around to allow for air circulation—this prevents stress or damage caused by expansion.
- Before final placement, check that the BESTÅ unit stands firmly and does not wobble; otherwise, instability will transfer directly to the glass top.

Summary:
- Keep the original surface
- Use rubberized pads as spacers
- Tempered safety glass 6-8 mm (1/4–5/16 inch)
- Have the glass cut to precise dimensions
- No permanent adhesion necessary

This way, you ensure safety and a visually pleasing result!

I want to emphasize this point again. Glass expands slightly with temperature changes, which can cause stress cracks if it rests on a rigid support. Therefore:

- The spacers should not be continuous but placed at specific points.
- The edges of the glass must be properly deburred.
- This is especially important when installed in rooms with large temperature fluctuations (e.g., near window fronts).

In your case, Shane33, if the furniture is located in the living area and not directly exposed to sunlight or heat from radiators, the classic solution with pads and the original top surface is sufficient.
