Along the hot, dry desert of the Sahara in Egypt, the Nile has created an oasis that enjoys extraordinary weather conditions. The two extremes combine to create ideal conditions for growing the world's best cotton - referred to as Giza cotton. All Giza cotton is assigned a number - the smaller the number the longer the staple and finer the thread. Traditionally, the finest cotton sheets on the market are woven from Giza 70 cotton.

Giza 45 cotton is exactly what makes Sferra's Giza 45 collection stand out from the pack. The thread is so fine that it is challenging to work with - let alone weave bedding from it. Sferra introduced its collection in 2008 following two years of research and development, and today remains the only bedding manufacturer confirmed to weave bedding from Giza 45 cotton.

As of summer 2019, Sferra readily offers eight separate Giza 45 sheeting collections. The percale sheets are cool and crisp, exceptionally airy yet relatively silky due to the fine threads. The sateens are silky like satin yet maintain a light, airy feel that is uncharacteristic of a cotton sateen sheet.

In the past, Giza 45 Percale has boasted a thread count in the vicinity of 500, while the sateens and sateen jacquards have been closer to 700. Sferra does not currently provide the thread count, emphasizing that these sheets transcend thread count. Ironically therefore, a Giza 45 Luxe collection remains available by custom order. Available only in White, Giza 45 Luxe features Giza 45 cotton woven to a thread count in excess of one thousand, and it is proclaimed to be the world's richest sateen.
