Hello everyone, I am planning to convert my Ikea BESTÅ shelving unit into a bench with integrated storage. Specifically, I would like to know the best way to reinforce the unit to safely use it as a seating surface, which materials besides the original components are practical, and how to incorporate a comfortable seat without losing the storage function. Does anyone have a step-by-step guide or practical tips on what to consider during the conversion—especially regarding stability, comfort, and appearance? I would appreciate constructive suggestions, including any experiences on how to repurpose the doors or drawers to make the bench multifunctional.
For stability: Reinforce the BESTÅ with short brackets or metal braces inside the corners. A thick plywood board makes a good seat surface, which you can cover with foam and fabric. You can keep the doors as storage flaps or remove them, depending on how much comfort you want.
Hello Peojo, your project sounds exciting! It is important to distribute the weight on the bench evenly. I recommend removing the back panel of the BESTÅ and replacing it with sturdy boards that serve both as the seating surface and the supporting structure. For comfort, a 5 cm (2 inch) thick foam with a removable cover is advisable. Also, make sure the fronts (doors or drawers) are fitted with high-quality hinges if you want to keep using them without interference while sitting.
I am wondering how reece70’s statement about short angles for stabilization actually increases the load capacity. Have you tested this or defined any load limits? Recommending just a plywood board as a reference seems a bit superficial to me, especially if the conversion is intended for long-term use as a seat bench. Certainly, tension-resistant reinforcements need to be installed inside; otherwise, the entire structure could sag or even get damaged with frequent use.

My goal is to reinforce the structure so that it can support at least 100 kg (220 lbs) without sagging or rattling. I know that the BESTÅ unit is not designed to bear seating loads, so I’m thinking about adding sturdy internal braces made of wooden battens and brackets. This isn’t meant to be a quick DIY fix but should be as durable and safe as possible.

I would also like to hear how you address stability at the back when the original back panel is removed.
Omitting the back panel involves certain risks. It usually plays a crucial role in torsional stability. Simply replacing it with a single board is questionable unless the component is adequately reinforced. It is recommended to use at least two, preferably three, cross braces or a frame that prevents lateral twisting.
Although plywood is suitable, its thickness should be properly dimensioned and it must be securely fastened to the side panels. Only then will the bench be truly durable and safe to use.
Before the modification, the physical loads should be carefully considered; otherwise, the result may be unsatisfactory.
