Super King Size Fitted Sheets

A super king mattress is as it sounds - it’s the top of the food chain, measuring 203cm x 203cm, a perfect square. This size gives plenty of room, plus its square shape makes it easier than any other bed size to make - just use our handy labelled corners to match the top left of the sheet to the top left of your mattress and you’re set, first time. Super king mattresses are also often deeper than the standard range of sizing, which is why the sheet wall (vertical depth) is 55cm rather than our typical 50cm, with a thick elastic lining the full perimeter so the sheet grips evenly.

Because two people (plus the odd kid, cat or dog) under one doona can get hot, the fabric of your king size fitted sheet needs to be of a certain quality. Our sheets are all 100% GOTS-certified organic cotton percale - a breathable, matte weave - meaning air flows through the sheets rather than getting trapped, stuffy and sweaty, which you’ll likely find with microfibre or polyester blends. Because Bonny sheets are made with long-staple fibres, they also last a long time and can handle regular washing. 

To complete your super king bed, add a super king flat sheet (280cm x 290cm) and king pillowcases (made for longer pillows that suit the super king better than standard pillows). For your doona, stick with the super king doona and super king quilt cover - for more details on our sizing and measurements, check out our bed linen size guide.
