Currently on display at Dutch Design Week, the range is based on retro camping equipment.
Designed to be easily and quickly put together without tools or screws, the framework of each piece is made from metal tubes that slide into stitched leather sleeves.
The Glissade chair has 12 pieces, including a curved metal rod that forms the back and a rectangular tube that supports the seat and front legs.
Once assembled the chair has a low back and wide seat, with the leather appearing as if it's been shrink-wrapped to the frame.
"I really like the way that camping equipment uses such a select amount of easily accessible materials that are very consistently applied throughout the designs," Heikoop told Dezeen.
"This way there is such an emphasis on the connection: if it's a screw, a weld or a hinge."
The range also includes a pair of benches and a table, each covered in leather of various colours. Heikoop graduated from Design Academy Eindhoven this year and has completed several other projects, including a series of paper masks for fashion label Kenzo.
"A lot of flat-packed systems can be intimidating and burden you from actually putting them together, without your toolbox," added the designer.
"Creating a straightforward system without any screws, fixings, tools, where you'd only need your hands, takes away this burden," he continued. "Instead it is drawing attention to the dialogue between two materials and their connecting aspect with each other."
This year has seen several designers create fresh takes on flat-pack furniture, from a modular collection designed to rival Ikea in ease-of-assembly to a range of wooden furniture designed to last longer.
Major design brands are also getting in on the act, with the Bouroullec brothers designing a customisable self-assembly sofa for Hay and Normann Copenhagen adding flat-pack lounge chairs to its range.
The entire Glissade collection is on display at the Design Academy Eindhoven graduate exhibition at Dutch Design Week, which takes place from 22 to 30 October 2016.
