10 of the best toddler mattresses to give your little one a good night's sleep

Section: Nursery
Toddler asleep in bed

As your toddler grows, so does his bed. Maybe you bought a cot bed that can easily be transformed into a toddler bed, or maybe it’s time to invest in a new ‘big bed’. It might be time, then, to buy a new toddler mattress.

Most toddlers either sleep in a cot bed, toddler bed, or even a single bed – you can buy small single beds, or normal-size single beds.

With so many products on the market for toddler beds, it’s easy to get confused. And given that toddler sleep problems keep us all awake at night, we know how important it is for your little ones to be comfy at night. Remember that safety comes first, and the safest mattresses are firm and flat, and protected by a waterproof cover. Having a cover keeps the mattress safe when there’s an accident – which definitely will happen – so it stays clean and dry, while you wipe clean the cover or even wash it if possible.

Buying a second-hand mattress isn’t recommended, however, we know sometimes it’s necessary. If you’re buying a second-hand mattress, make sure it has always been covered by a waterproof cover, and check that it’s still firm and flat, with no damage or rips.

Winner of the Silver award in the M&B Awards 2020 Best Sleep Product, the Naturalmat Quilted Mattress is handmade from natural materials and scored highly with our real mum testers. Organic coconut fibre makes the mattress breathable and self-ventilating, making it great for asthma sufferers. 

Mum Jasmine tested this mattress for the M&B Awards 2020; she said: "This is an excellent mattress. Before using this one I would lay a duvet over the top to provide extra comfort and I didn’t need to with this mattress. My daughter has slept really well since using this mattress, she would toss and turn for quite a while trying to get comfortable but now she snuggles down and goes straight to sleep."

Mum Candice Sharp tested this mattress in the M&B Awards 2017; she said: "This is a high quality mattress and my baby now sleeps through the night thanks to the comfort factor. I would highly recommend this product as you can see straight away it is a high end mattress and well worth the cost especially for a cot bed that will be used for a number of years. I also really like the fact it's made in Britain."

What size toddler mattresses are there?

  • Cot mattress: 60cm x 120cm
  • Cot bed or toddler bed mattress: 70cm x 140cm
  • Small single mattress: 75cm x 190cm
  • Single mattress: 90cm x 190cm

Small single beds are narrower than a normal single, so they’re ideal for small box rooms, or spare beds for guests.

It’s important to make sure your mattress fits your bed frame properly, and also check the size of bed you’re buying will fit in your child’s room – trust us, there’s nothing worse than ordering a bed and finding it’s too big when it gets delivered.

What sort of mattresses can you buy?

  • Traditional spring mattresses: Feature a series of connected springs for support over the entire sleeping area.
  • Pocket spring mattresses: Individual springs move independently to fit to body shape and relieve pressure.
  • Combination mattresses: Combine springs, and a layer of memory foam, latex or gel, providing enhanced comfort and pressure relief.
  • Advanced mattresses: The ultimate in comfort and support. Advanced materials like memory foam, latex or gel provide enhanced support and comfort.
  • Memory foam mattresses: Innovative and responsive memory foam; conforms to your shape and provides superior comfort.
