Your baby spends a lot of time lying down: napping, stretching, kicking and doing tummy time. What goes underneath them matters. This guide explains how to choose the right baby matt (baby mat or mattress) for the cradle, the floor and the bed, which materials work best, how to set up a safe sleep space and how to keep it clean.
Quick Answer
For sleep, choose a thin, firm, flat mattress that fits the cradle or cot snugly with no gaps, with a breathable, washable cover. For play and tummy time, use a soft, wipeable, foldable play mat on the floor. A matt placed on an adult bed is for supervised play or changing only, not for unsupervised sleep. Keep pillows, loose blankets and soft toys off any sleep surface.
Types of Baby Matts
| Type | Use it for | Look for |
|---|---|---|
| Cradle or hammock mattress | Sleep and naps in the cradle | Thin, firm, flat, snug fit, breathable |
| Play mat | Floor play and tummy time (awake, supervised) | Cushioned, wipeable, foldable, non-slip |
| Dry sheet or changing mat | Nappy changes and protecting the mattress | Waterproof, quick-drying, washable |
| Decorative or embroidered matt | Supervised play and photos | Soft fabric, secure stitching, no loose threads |
What to Look for in a Baby Sleeping Mattress
- Firm and flat: supportive, not soft or sinking. It shouldn't take the shape of your baby's head.
- Snug fit: no gaps between the mattress and the cradle or cot sides.
- Thin: especially in a cradle or hammock. Avoid thick padding.
- Breathable cover: cotton helps prevent overheating.
- Washable: a removable, washable cover saves you on messy days.

Best Materials for a Baby Matt
- Soft on skin: cotton and muslin feel gentle on sensitive skin.
- Breathable: babies can't regulate temperature well yet.
- Easy to clean: spit-up and leaks are part of the deal.
- Waterproof layer: under the sheet or as a dry sheet, to protect the mattress.
Setting Up a Safe Sleep Space
- Place your baby on their back to sleep, on a firm, flat surface.
- Use your baby's own sleep space, such as a cradle or cot, ideally in your room.
- Keep pillows, bolsters, loose blankets, bumpers and soft toys out.
- Dress your baby in light layers and keep the room comfortably cool.
- Don't put your baby to sleep on an adult bed, sofa or cushion on their own.

Cradle, Floor or Bed: Which Matt Where?
In the cradle: a thin, firm mattress that fits snugly. On the floor: a cushioned play mat for tummy time and play, such as the reversible foldable foam play mat. On your bed: a dry sheet cum changing mat is handy for changes and supervised play, but always stay with your baby, and move them to their own sleep space for sleep.
Embroidered and Decorative Matts
Round, embroidered and printed matts look lovely in the nursery and in photos. Use them for supervised play, and check that the stitching is secure with no loose threads or small decorations your baby could pull off. For sleep, stick to a plain, firm, flat mattress.
Caring for Your Baby Matt
- Spot-clean spills straight away.
- Wash covers as per the care label with a mild baby detergent.
- Air the mattress regularly and let it dry fully.
- Wipe foam play mats with a damp cloth.
- Replace a mattress that sags, cracks or no longer fits snugly.
