Junior Bed vs Toddler Bed vs Single Bed – Which Sheet Do You Need?

Bed sizes for young children can be confusing. Here's a clear guide:

  • Toddler bed – Often the same size as a cot bed mattress (70cm x 140cm). If your child has transitioned from a cot bed to a toddler bed using the same mattress, you may be able to use cot bed fitted sheets. Always measure your mattress to confirm.
  • Junior bed – Slightly larger than a toddler bed, typically around 70cm x 160cm or 75cm x 175cm. Requires junior-specific sheets – standard single sheets (90cm x 190cm) will be too large.
  • Single bed – Standard UK single mattress is 90cm x 190cm. Once your child moves to a single bed, standard single fitted sheets apply.
  • Our advice – Always measure your mattress before purchasing. Junior and toddler bed sizes are not fully standardised, so checking dimensions is essential.

Frequently Asked Questions

Junior bed mattresses are typically around 70cm x 160cm or 75cm x 175cm, though sizes vary between brands. This is larger than a cot bed mattress (70cm x 140cm) but smaller than a standard single mattress (90cm x 190cm). Always measure your junior bed mattress – length, width, and depth – before purchasing. Standard single sheets will be too large for a junior bed and won't stay in place safely. Look for sheets specifically listed as junior bed size and check the dimensions match your mattress.

Possibly – it depends on whether your toddler bed uses the same mattress as the cot bed. Many cot beds convert to a toddler bed using the same 70cm x 140cm mattress, in which case your existing cot bed fitted sheets will fit perfectly. However, if your toddler bed has a different mattress size, you'll need sheets sized for that mattress. Always measure your mattress before purchasing to confirm the right size.

Most children transition from a cot bed to a toddler or junior bed between 18 months and 3 years, though there's no fixed rule. The main trigger is usually when your child starts climbing out of the cot bed, which becomes a safety risk. Some parents also make the transition when a new sibling needs the cot bed. There's no rush – cot beds are safe and comfortable for children up to around 4–5 years if they're not climbing out. When you do make the move, consider adding a bed guard to prevent falls during the night.
