What length of braided cot bumper should I choose for a 120 × 60 cm cot?

Braided cot bumper in a baby cot

For a 120 × 60 cm cot, it is not just the mattress size that matters. First, determine which sides you want to cover with the bumper, and then measure the internal length of the specific cot.

Quick answer: The geometric internal perimeter of a 120 × 60 cm size is 360 cm. Therefore, a 360 cm bumper is usually compared for the entire perimeter, a 180 cm bumper for one long and one short side, and a 120 cm bumper for one long side.

How to calculate the required length?

Braid along the long side of the cot

Use the sum of the internal sides you want to cover. For the entire rectangle, 2 × (120 + 60) = 360 cm applies. However, the 120 × 60 cm dimension usually refers to the mattress; the actual internal length of the cot may vary slightly.

What do common lengths approximately cover?

  • 120 cm – one long side of the cot.
  • 180 cm – one long and one short side: 120 + 60 cm.
  • 240 cm – one long side and both short sides: 60 + 120 + 60 cm.
  • 360 cm – the entire geometric perimeter: 120 + 60 + 120 + 60 cm.

Compare, for example, a 120 cm braided bumper and a 360 cm braided bumper.

Why might exactly 360 cm not fit perfectly?

Detail of braided bumper thickness

The result is influenced by the thickness of the braid, the rounding of the corners, the ends, the method of attachment, and manufacturing tolerances. Some manufacturers therefore state their own recommended calculation for thicker models. Do not estimate the length: follow the instructions for the specific product.

Important note on sleep: The NHS, the American Academy of Pediatrics, and the Lullaby Trust recommend keeping the infant's sleep area free of bumpers and other soft items. Follow current safety recommendations and the manufacturer's instructions.
