Best travel cot mattress: the top 7 choices

The best travel cot mattress is firm, flat and sized to fit the cot snugly, without gaps. There is no universal travel-cot mattress size, so the cot’s internal sleeping area determines which product is suitable.

These options cover current UK products with stated dimensions, prices and, where available, Argos customer ratings. Argos lists six products in its travel-cot-mattress category.

Prices and ratings come from the Argos travel cot mattress listings, except for the two Tiny Dreamer products, whose prices and dimensions are listed by The Tiny Bed Company. Sale prices can change.

Travel cot mattress size: measure before you buy

Match the mattress to the cot’s internal sleep area. The NHS describes a suitable cot mattress as firm, flat and snug-fitting, with no space where a baby’s head could become trapped.

Measure the inside length and width of the mattress base, then compare both measurements with the product listing. Check the fit on all four sides after installation and make sure the mattress lies flat. Common sizes in current UK listings include 95 x 65cm, 100 x 70cm, 104 x 74cm, 94 x 66cm and 120 x 60cm. These measurements are not interchangeable.

The Cuggl 104 x 74cm mattress illustrates why similar-looking sizes can still be wrong. Argos states that this mattress is not suitable for a Cuggl cot measuring 93 x 63.5cm, a Cuggl Travel Cot with Bassinet using a 92 x 64cm mattress, an Airpod cot or a cot measuring 106 x 72cm. The mattress itself measures 104 x 74 x 5cm.

Foldable travel cot mattress: which type suits you?

A foldable travel cot mattress is useful for car journeys, luggage and storage. The Baby Elegance 100 x 70cm model is listed as foldable and costs £24.00 at Argos on sale. For a 95 x 65cm cot, The Tiny Bed Company lists the Tiny Dreamer Premium Foam Folding Mattress at £65.95; its 104 x 74cm version is £69.95.

For a 120 x 60cm travel cot, Cotton Haven lists a travel-cot mattress in 120 x 60 x 10cm and 120 x 60 x 13cm options. The same listing includes 95 x 65cm and 100 x 70cm sizes, with thicknesses from 5cm to 13cm.

Best travel cot mattress for Hauck, Cuggl and other brands

Choose by the exact cot model and sleeping-area dimensions. The Tiny Dreamer range includes named options measuring 100 x 69cm for the Joie Baby Commuter Logan, 105 x 60cm for the BabyBjörn travel cot, 94 x 66cm for the Nuna Sena Aire and 95 x 65cm for the Red Kite Sleep Tight.

For Cuggl, the 104 x 74cm mattress is one specific option rather than a fit for every Cuggl travel cot. A model-specific listing is useful when its dimensions correspond to the cot’s sleep area.

Best travel cot with a thick mattress: what to look for

Thickness alone does not determine suitability. NHS guidance recommends a firm, flat mattress that is clean, dry, waterproof and free from rips or tears, with a fire-resistant label present. The Lullaby Trust also says that travel-cot mattresses are often thinner and harder than mattresses in permanent cots.

Cotton Haven lists thickness options from 5cm to 13cm across its sizes. These are product specifications, not a universal recommendation for safe travel-cot use. Never put folded blankets or a quilt underneath a baby to make a mattress softer; The Lullaby Trust advises against this practice.

Travel cot mattress topper: should you use one?

A topper is not the best solution for a hard-feeling or thin travel-cot mattress. Added padding changes the sleeping surface and can affect the fit. Use a replacement mattress made for the cot instead.

For hygiene, use a fitted sheet that fits the mattress properly. The Cuggl 104 x 74cm listing recommends a fitted sheet, preferably waterproof. Keep the mattress clean and dry, and replace it if the cover or surface has rips or tears.

How to buy the right travel cot mattress

  • Start with the size: use the cot’s internal length and width, not the outside dimensions.
  • Consider the model: named options are available for several Hauck, Cuggl, BabyBjörn, Nuna, Joie and Red Kite products.
  • Prioritise the sleeping surface: choose a firm, flat and waterproof mattress that is clean and undamaged.
  • Choose folding construction when needed: compare the folded format with your transport and storage space.
  • Look for the label: NHS guidance recommends a fire-resistant label.

The £24.00 Baby Elegance 100 x 70cm model is the lowest current sale price among the Argos products listed here. The £28.00 Cuggl model is a mainstream 95 x 65cm option with 346 Argos reviews. The Tiny Dreamer products provide specialist folding formats in named dimensions.

Frequently asked questions

Is it safe to put a mattress in a travel cot?

Yes, when it is firm, flat and correctly sized for the travel cot. It must fit snugly without gaps, remain clean and dry, and have a waterproof covering. Do not place folded blankets or a quilt underneath the baby. The NHS cot mattress guidance sets out these requirements.

Do travel cots need a mattress NHS?

The NHS says a baby’s cot mattress should be firm, flat and snug-fitting, with no gaps, and recommends a waterproof cover. Use the mattress supplied with the travel cot or an approved replacement in the required dimensions.

What mattress fits a travel cot?

The correct mattress matches the cot’s internal sleep-area dimensions and fits snugly on every side. Current listings include 95 x 65cm, 100 x 70cm, 104 x 74cm, 94 x 66cm and 120 x 60cm, but these sizes are not interchangeable.

What thickness should a travel cot mattress be?

No universal thickness is specified by the safety guidance. Prioritise a firm, flat mattress with the correct fit. Cotton Haven’s available thicknesses range from 5cm to 13cm, but these are individual product specifications rather than a general safety recommendation.
