Quick Answer

Start with a waterproof mattress protector, then add a fitted sheet that matches the mattress size. If using a Woolnest liner, place it over the fitted sheet for easy cleaning and a custom look. Always check that the sheet is snug and wrinkle-free before putting your baby down.

Why Layering Matters for Cot Bed Safety and Comfort

Layering a cot bed correctly helps protect the mattress, makes changing bedding quick, and keeps your baby comfortable. A fitted sheet that fits tightly reduces the risk of loose fabric, while a liner adds an extra barrier that is easy to wash. The key is to avoid any bunching or gaps that could pose a suffocation hazard.

Choosing the Right Fitted Sheet for a 120x60 Cot Mattress

A 120x60 fitted sheet is designed specifically for standard cot mattresses of that size. Look for one with deep pockets and elasticated edges so it stays put even when your baby moves. The Mokee Cot Bed Fitted Sheet in Melange Grey uses soft, breathable cotton jersey with stretch, ensuring a smooth fit without excess fabric.

When and How to Use a Cot Bed Liner

A cot bed liner, like the Woolnest Liner, sits on top of the fitted sheet to protect the basket or mattress from spills and mess. It is not a mattress protector but a removable layer that can be washed separately. Place it flat over the fitted sheet and tuck the edges under the mattress if the liner has elastic or ties. This adds a pop of colour and simplifies mid-night changes.

Step-by-Step Cot Bed Layering Guide

  1. Step 1: Fit the Mattress Protector: Place a waterproof mattress protector over the bare mattress. Tuck the elastic corners under the mattress so it lies flat and smooth. Common mistake: using a protector that is too big can cause wrinkles. Check that it matches the 120x60 size.
  2. Step 2: Add the Fitted Sheet: Stretch the fitted sheet over the mattress protector. Align the corners and pull the elastic edges under the mattress. Smooth out any wrinkles by running your hands over the surface. Checkpoint: the sheet should be taut enough that you cannot pinch more than an inch of fabric. Loose sheets are a suffocation risk.
  3. Step 3: Place the Liner (Optional): If using a liner like the Woolnest Liner, lay it on top of the fitted sheet. Tuck any elastic or ties under the mattress or secure them as per the product instructions. Common mistake: placing the liner under the fitted sheet. It should go on top so you can remove and wash it without disturbing the sheet.
  4. Step 4: Final Safety Check: Run your hand over the entire sleep surface. Ensure there are no loose corners, wrinkles, or excess fabric. The sheet and liner should be smooth and secure. Checkpoint: if you can lift the sheet easily from any corner, re-tighten the elastic. A safe cot bed has a firm, flat surface with no gaps.
