Hildur chair

Comfortable seat & backrest

The fabric is soft and breathable, ensuring comfort when in use over a long time. The front edge of the seat is soft and yielding, further adding to the chair’s comfort. Both the seat and backrest are easily replaceable, making the chair both durable and easily maintained.

Lighter chair
less physical strain

A light chair means it’s easier to manoeuvre and set up, on or off a trolley, which saves both time and labour.

Hildur chair stack

up to 40 chairs

Stackable upholstered steel frame chairs generally weigh between 6 and 8 kg (13–17 lbs) but the Hildur chair is only 4 kg (8.8 lbs). Its light weight improves safety when stacking and moving around on a trolley. This also makes it easier to stack the chairs higher and save storage space.

Hildur chair linking glides

Easy to link together

The linking glides are replaceable and transparent. They are made of polycarbonate plastic and their base is made of TPU soft plastic, which can be replaced separately.

Strong lightweight frame

The steel frame is made of a very strong, high-tension, lightweight tube, welded together by a robotic welding machine.

Hildur chair numbering system

Numbering system

The numbering system is simple and can be adjusted to different needs. Printing the numbers is easy and can for example be done using a label maker app for smartphones. The numbers can be made to fit different setups and they are easy to store.


The Hildur chair is the ideal choice for multifunctional spaces like conference halls, hotels, schools and workplaces. It combines comfort, durability and practicality, achieved through innovative design and attention to detail.

The Designer
Valdimar Harðarson

Valdimar’s ambition has always been to design a stackable chair that is lightweight, comfortable and multifunctional. He has been working on and improving his design for the past 12 years. In 2010 he introduced the chair, which has, among other places, been in use at the Harpa Concert and Conference Centre in Iceland since its opening. With the newest version, Valdimar has finally fulfilled his design ambitions. The chair is both beautiful and functional: it is light, easy to move, and stackable, which makes it ideal for a number of different functions.

Architect Valdimar Harðarson was born in Reykjavík, Iceland, in 1951. He graduated from Lund University in Sweden in 1980 and started his own company when he returned to Iceland. He is one of the founders of ASK Architects, a leading architectural firm in Iceland. Apart from his work on buildings, Valdimar has designed furniture for both the Icelandic market and international buyers. Among his early works is the folding chair Sóley, which was introduced in 1983 and has since become a classic piece. Sóley has earned Valdimar a number of awards, including the Möbel des Jahres (Chair of the Year) award and Stuttgart Design Center prize in Germany, the Roscoe Award in the USA and Design Prizes in Japan, as well as the Deutscher Designer Club medaille. Over the course of his career, Valdimar has worked on several buildings and urban planning all over Iceland. ASK Architects have won numerous awards, and Valdimar’s design for the summer house Gata in Iceland was nominated for the 2007 Mies van der Rohe Award.
