Crib Fitted Sheets

Crib Fitted Sheets – Soft, Safe & Snug for Your Baby's Crib

Shop our range of crib fitted sheets – breathable, machine-washable sheets designed to fit standard crib mattresses snugly and securely. A well-fitting sheet is one of the most important safe sleep essentials, and having a rotation of quality sheets makes night-time changes quick and stress-free. Free UK delivery available.

Crib vs Cot vs Moses Basket – Which Sheet Do You Need?

Fitted sheets are size-specific – always match the sheet to your mattress dimensions:

  • Crib fitted sheets – Fit standard crib mattresses, typically 40cm x 90cm or 45cm x 90cm. Cribs are used from birth to approximately 6 months. Always measure your crib mattress before purchasing.
  • Cot fitted sheets – Fit standard cot mattresses, approximately 60cm x 120cm. See our cot fitted sheets.
  • Cot bed fitted sheets – Fit larger cot bed mattresses, approximately 70cm x 140cm. See our cot bed fitted sheets.
  • Moses basket fitted sheets – Smaller oval or rectangular sizes for Moses baskets. See our Moses basket fitted sheets.

Safe Sleep & Sheet Fit

The Lullaby Trust advises that sheets must fit the mattress snugly with no loose fabric that could cover your baby's face. A sheet that is too large is a safety hazard. Always check the sheet dimensions match your mattress size, and look for sheets with deep pockets and strong elastic that stay firmly in place all night.

Why Choose Our Crib Fitted Sheets?

  • 100% breathable cotton – Soft, temperature-regulating natural fibres
  • Perfect fit – Deep pockets and strong elastic that stay in place all night
  • Hypoallergenic – Gentle on newborn and baby skin
  • Machine washable – Easy care, maintains softness wash after wash
  • Available in multiple colours – To complement your nursery decor

Frequently Asked Questions

Crib mattresses are not fully standardised, but most measure approximately 40cm x 90cm or 45cm x 90cm. Always measure your crib mattress – length, width, and depth – before purchasing a fitted sheet. A sheet that is too large will have loose fabric that can cover your baby's face, which is a safety hazard. Look for sheets with deep pockets and strong elastic that grip the mattress firmly and don't come loose during the night. Crib sheets are smaller than cot sheets (60cm x 120cm) and cot bed sheets (70cm x 140cm) – these are not interchangeable.

We recommend having at least 3 crib fitted sheets in rotation. Newborns are particularly prone to nappy leaks, posseting, and sick – often at 2am when you least want to be doing laundry. With 3 sheets, you always have one on the crib, one clean and ready, and one in the wash. This is especially important in the early weeks when you may be changing the sheet multiple times a night.

No – standard cot sheets (designed for 60cm x 120cm mattresses) are too large for a crib mattress (typically 40–45cm x 90cm). A sheet that is too large won't stay on the mattress properly and creates a safety hazard, as loose fabric can cover your baby's face. Always use sheets specifically sized for your crib mattress. If you're unsure of your mattress size, measure it before purchasing.
