Enjoy a flawless fit and indulgent comfort every night with our 450 Thread Count Pima Cotton Extra Deep Fitted Sheet. Designed for modern, deeper mattresses, this sheet solves one of the most common bedding frustrations, fitted sheets that pull loose, ride up, or simply don’t fit properly once toppers and protectors are added.

Crafted from 100% pure Pima cotton, prized for its extra-long staple fibres, this fitted sheet delivers exceptional smoothness, strength and durability. The fibres are carefully combed and woven from single-ply yarns to create a true 450 thread count sateen fabric. The result is a beautifully smooth, lustrous finish that feels silky against the skin while remaining breathable, moisture-absorbing and temperature regulating, ideal for comfortable sleep all year round.

Available in a range of sizes and colours, this fitted sheet has a full depth of 38cm (15”), designed to fit mattresses up to 30cm (12”) deep. The extra depth ensures a perfect, no-pull-out fit. We recommend fitted sheets to sit 8cm (2”-3”) deeper than the total thickness of your mattress (+ any topper), with any extra fabric held tidily underneath the mattress.
