S1 stools by Alexander Lotersztain for Derlot

S1 stool and side table by Alexander Lotersztain for Derlot

Dezeen Showroom: the minimalist S1 stool created by Australian designer Alexander Lotersztain for furniture brand Derlot is designed to double as a side table.

Intended for both indoor and outdoor use, S1 has a deliberately simple form that Lotersztain modelled on an I-beam – a structural member with an I-shaped cross-section.

"Strikingly minimalist, S1 captures the modesty of a stool yet quietly commands any space," said Australian brand Derlot.

"S1 can be both a stool or a side table for indoor or outdoor use – a solid reminder that simplicity equals versatility."

Lotersztain crafted S1 from the durable thermoplastic called low-density polyethylene (LDPE), which means it is fully recyclable material at the end of its life, according to the brand.

The design is available in a range of colours, including orange and green, as well as in three heights to maximise its versatility.
