Bartlett died yesterday (12 August). He had been suffering with chronic obstructive pulmonary disease for some time, and succumbed to an infection after a recent operation. 

He was a multi-talented designer who worked in glass, steel, and paper-based substrates. 

He found fame in the 1960s with his iconic 'Tab' flat-pack cardboard chair, produced in association with Thames Board Mills. 

It was the first paper chair that could support an adult’s weight, and retailed for the equivalent of £2.25 at the time. 

In the year 2000, one of the original chairs sold at Christie's for nearly £400.

The Tab chair featured in a book about landmark designs

Known as ‘Barty’ to family and friends, he worked with many high-profile clients and collaborators including Lady Gaga, Isabella Blow and milliner Philip Treacy, as well as brands including Habitat and Conran. 

He was well-known in the printing industry for his Brand-it range of printable cardboard furniture designs, which are ideal for exhibitions, pop-up shops and events, and promotions. 

Bartlett regularly exhibited his work and spoke at Fespa events. 

Long-standing associate John Charnock, founder of Print Research International, paid tribute and said: “He was a fantastic designer and a great person. Barty was a real glass-half-full type of person, the most positive, upbeat person even in the face of challenges in his life. 

“He was a dear friend and an amazing designer.”

Bartlett also worked with Cambridge-based interactive print experience developer Novalia. 

After hearing the sad news yesterday, founder and CEO Dr Kate Stone commented: “He will be missed by many people. I know he impacted my life and those around me. Anyone who unswervingly dedicates their life to their creative passion is always my hero. Today a hero died.”

Bartlett is survived by his son, Stefan.
