A note on Nigerian bed sizes
Nigerian furniture makers and importers frequently use US naming conventions — a Nigerian "King" is often 160 × 200 cm, wider than the UK King (150 cm). We recommend measuring your mattress before ordering a fitted sheet. For all other pieces — flat sheets, duvet covers, pillowcases — our sizes offer generous overhang and will fit Nigerian beds comfortably.
If you're unsure, our team is happy to help you select the right size — get in touch.
