Rather than containing large exhibitions, rooms in the newly opened extension are themed around specific individuals.
The display dedicated to Morrison – who provided furniture to decorate the Switch House interiors – is titled Thingness. It includes works that date back to 1984, alongside detailed commentary from the designer himself.
Morrison's Thinking Man's Chair, the first piece he created for Cappellini in 1986, is among the objects on display. Its dramatic curved structure is based on an antique chair that was missing its seat, and was modelled using a packet of pipe cleaners.
The collection also includes other pieces created for the Italian brand, like Morrison's Red Carpet and Universal System of storage.
Visitors can gain further insight into Morrison's design process through models and drawings for his Air Chair for Magis.
Other highlights include a showcase of the designer's foray into electronics – a kettle designed for Muji and set of alarm clocks for Punkt – as well as his longstanding partnership with lighting brand Flos.
A prototype of his Superloon floorlamp is on display, alongside his earlier Smithfield pendant.
Morrison's Luxmaster floor lamp, which includes an adjustable light and a wound cable similar to that of old telephones, also features.
Thingness continues at the Tate Modern until 2 October 2016.
