The big duvet question
Can I wash a super-king duvet at home?
Sometimes — but a large-capacity machine is the safer bet.
Start around 12kg+
Many super-king duvets need a 12kg or larger drum, especially when thick or feather/down filled.
Check the care label. If the dry duvet is wedged into the drum with no room to move, take it to a laundrette rather than risking poor rinsing or damage.
