Care

Cleaning

Warm soapy water and a soft sponge is all you need. Avoid abrasive cleaners or harsh chemicals.

Weight & Use 

The full version supports up to 120 kg. Standing on the stool is not recommended. The Whang (incomplete head) is not intended for sitting or standing — best used as a side table or decorative object.

Material & Process

Photography & Colour 

We do our best to photograph each piece accurately, but lighting, shadows, and screen calibration all affect how a piece reads on camera. Our pieces are batch-to-batch by nature — colour and tone will shift between production runs. What you receive will always be within the character of the piece shown, but may not be an exact match. We encourage you to embrace the individuality of your piece.

The Narrative of Colour Traces 

This is intentional. Where a traditional manufacturer would discard colour blends, we do not. In our single colour Classics, subtle traces of other colours are celebrated — this is how we originally began, making one-off pieces with distinct marble patterns. The more striking versions now live in our Rare and Lookchoop collections, but traces remain in the Classics because we believe in individuality.

Batch-to-Batch Variation 

We work with the natural colour of recycled materials rather than standardising with dye. While we try to match each previous batch as closely as possible, each production run will vary slightly in tone.

Natural Characteristics 

Every piece goes through quality control before it leaves us. Some marks are unavoidable in small-batch recycled plastic production — these are features, not defects:

Mould cut lines: a line runs along each side of the leg near the top, often resulting in a slightly lighter shade. A natural result of the production mould.

Structural visibility: because our stools are semi-transparent, the internal bone structure may be more visible on some pieces depending on cooling rate, which varies piece to piece.

Minor surface lines and crawling: when reclaimed materials are cleaned and reinjected, trace moisture can remain, resulting in crawl lines on the surface. We find these quite charming. Pieces with particularly distinct crawl lines, air gaps, or tiny injected dust particles often find their way into our Rare collection.

If your piece arrived cracked, broken, or structurally compromised — contact hello@rumbabor.com within 7 days with clear photos and video of the outer packaging, unpacking and the damaged item. We will take care of you.

Our Collections

Classic

Single colour pieces, partly intentional, partly material-led. Our Classic colours are mixed from available recycled polypropylene — each batch carries its own subtle tone, and no colour can be exactly repeated.

Look Choop

Began as a spontaneous repurposing of leftover legs and seats from the Classic collection that didn't match. Now intentionally made to be multicoloured — typically in 4–5 colours — each combination is still determined by available materials and may be one of a kind.

Whang

Features the incomplete CHOEI heads — traditionally discarded as production waste where spontaneously missing rims create organic forms. This happens through a few technical errors in the production process where we celebrate the process. These are recommended as side tables or decorative objects only. Not suitable for sitting or standing.

Krasue

Glow in the dark Choei ~ Requires light exposure to charge before glowing ~  in collaboration with Neighborh00ddrama

Rare

Truly one of a kind pieces. Replacing the original PVC injection method with hand-poured recycled polypropylene creates marble-like patterns, transforming what was once identical, mass-produced into objects of chance.  Embracing the spontaneity of an uncontrolled process, no two pieces ever form the same way, each one a unique result of the material and process. 

Cherng

A side table that brings together two distinct remnants of Thai material culture. It features incomplete Choei stool heads, traditionally discarded as production waste, where spontaneously missing rims create unique, organic forms. These are paired with repurposed dead-stock ceramic balusters, a nostalgic fixture of Roman-influenced Thai railings with a local twist of vibrant colours.

Assembly

Your stool arrives flat-packed with one seat and four leg pieces. Attach each leg to the seat and screw the legs to the seat with a hand or electric screw.
