Cot Bed Fitted Sheets

Cot Bed Fitted Sheets – Soft, Breathable & Safe for Every Night's Sleep

Shop our range of cot bed fitted sheets – 100% cotton, breathable, and designed to fit standard cot bed mattresses snugly and securely. A well-fitting sheet is one of the most important safe sleep essentials, and with frequent washing a necessity, having a good rotation of quality sheets makes life significantly easier. Free UK delivery available.

Cot Bed vs Cot vs Travel Cot – Which Sheet Do You Need?

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

  • Cot bed fitted sheets – Fit standard cot bed mattresses, approximately 70cm x 140cm. Cot beds convert to a toddler bed, so these sheets last from around 6 months up to 4–5 years – excellent long-term value.
  • Cot fitted sheets – Fit smaller standard cot mattresses, approximately 60cm x 120cm. See our cot fitted sheets.
  • Travel cot fitted sheets – Fit travel cot mattresses, which vary by brand. See our travel cot fitted sheets.
  • Moses basket & crib sheets – Smaller sizes for newborn sleep spaces. See our Moses basket fitted sheets and brand-specific crib sheets.

How Many Cot Bed Fitted Sheets Do You Need?

We recommend having at least 3 fitted sheets in rotation. Nappy leaks, sick, and spills happen at the worst times. With 3 sheets, you always have one on the cot bed, one clean and ready, and one in the wash.

Why Choose Our Cot Bed Fitted Sheets?

  • 100% breathable cotton – Temperature-regulating natural fibres keep your baby cool and comfortable
  • Perfect fit – Deep pockets and elasticated edges that stay firmly in place all night

Frequently Asked Questions

Standard cot bed mattresses are approximately 70cm x 140cm, so you need a fitted sheet designed for this size. This is larger than a standard cot mattress (60cm x 120cm) – using the wrong size is a safety risk, as a sheet that is too large will have loose fabric that can cover your baby's face. Always check your mattress dimensions before purchasing, and look for sheets with deep pockets and strong elastic that grip the mattress firmly and don't come loose during the night. Cot beds typically last from around 6 months up to 4–5 years, making cot bed sheets a long-term investment.

No – standard cot sheets (designed for 60cm x 120cm mattresses) are too small for a cot bed mattress (70cm x 140cm). A sheet that is too small won't stay on the mattress properly and creates a safety hazard. Always use sheets specifically sized for your mattress. If you're unsure of your mattress size, measure it before purchasing – length, width, and depth – and match to the sheet's listed dimensions.

Ideally, wash cot bed fitted sheets at least once a week – more frequently if there are nappy leaks, sick, or spills. Babies and toddlers sweat more than adults relative to their body size, and sheets can harbour dust mites and bacteria quickly. Wash at 40–60°C with a gentle, fragrance-free detergent suitable for baby's sensitive skin. Having 3 sheets in rotation means you can change immediately after an accident without waiting for a wash cycle to finish.
