Circle has prototyped many types of materials over the past three years in search of the right combination of functionality, durability, and style when it comes to the construction and finishes. The following materials pages will give insight into the attention to detail and quality of build that goes into each piece of Circle furniture.


Fenix NTM

FENIX NTM® is a super opaque nanotech material used by Circle for surfaces. It is an innovative interior design product, created by Arpa Industriale, that combines elegant aesthetic solutions with state-of-the-art technological performance. With low light reflectivity, its surface is extremely opaque, anti-fingerprint and can thermally heal any superficial micro-scratches. It also features a very pleasant soft touch. The swatch on this page represents the colours Circle furniture can be surfaced in.

Circle use ‘Arctic White’ HI-MACS® by Gunnersen, an advanced polymer resin technology developed by LG Hausys®. The acrylic resin acts as a reinforcing agent, adding extra strength while creating a non-porous surface that can be repaired if scratched or chipped. The acrylic also allows for seamless joins giving every surface a sleek, smooth finish.


Inspired by industrial raw materials but without the constraints of weight, Circle uses surface laminate ‘White Cement’ – a pale, white, realistic concrete with soft grey shadow, ‘Grey Cement’ – a mid-toned, grey, realistic concrete with mid grey shadow and ‘Dark Cement’ – a dark, cool grey, realistic concrete with near black shadow. These lightweight alternatives to concrete provide a true raw concrete appearance without the need for reinforcing steel, curing and casting.

Birch Plywood

Circle uses Birch Plywood because of its warmth and natural markings. Plywood uses more of the log than other timber which makes it much more effective as a resource. Also, kilo for kilo it is stronger than steel, as well as being a longer lasting more durable timber.

Solid Oak

One of the most popular timbers to use in fine furniture making, Circle Oak has great strength and hardness with very appealing grain markings.


A simple and trusted way to make bases, legs and frames Circle uses Square Hollow Steel (SHS) and RectangleHollow Steel (RHS) for all column based products. The SHS/ RHS in the Oosoom range is powder coated white to finish.

Synthetic Leather

For the interior of Circle furniture drawers an ivory synthetic leather is used. Being 100% polyester the synthetic leather is very durable: resistant to most chemicals, stretching and shrinking, wrinkle resistant and abrasion resistant with a soft touch.
