The Sundae and Fenster series both focus on seating but to very different effects. While the former consists of chubby soft furnishings geared towards comfort, the latter sees stark, black metal frames left exposed by transparent seats and backrests.
All are currently being exhibited at the fair, which forms part of Dezeen's Virtual Design Festival and gives designers and brands an affordable platform for launching new products.
Envisioned by the studio's design and production coordinator Jason Ju, the Sundae Lounges are named after their plump, curvy shape, which is reminiscent of soft-serve ice cream or bunched-up marshmallows.
The chairs and stools in the Fenster collection, on the other hand, play up the contrast between their dark frames and otherwise entirely clear exteriors, in a nod to the traditional design of steel-rimmed crittall windows.
Designers and DesignByThem founders Sarah Gibson and Nicholas Karlovasitis, who go by the name Gibson Karlo, grounded the seats' unconventional use of acrylic in elegant, recognisable shapes that allow the series to feel at home in a range of different settings, including the outdoors.
Finally, their Confetti pieces celebrate rather than conceal the natural texture of recycled plastic, which sees a rainbow array of different coloured fragments mashed together into an almost Memphis-style pattern.
Across the collection, the material is used in the shape of a cylindrical module to form everything from table legs to entire plant pots.
DesignByThem was established in 2007 and as a representative of Australia's burgeoning design scene it hopes to play a part in defining the country's own, distinct style.
"Australian design is definitely on the global stage and I believe Australia has such a broad range of styles and aesthetics, just like we do people," said Ju.
"This is what makes us unique as a Westernised country."
