Bassinet Sizes

Bassinets are available in a range of sizes. The most common is the 76 x 40cm size, which is used by a number of brands including Cariboo.

Please check your mattress size before ordering to ensure it will fit the linen you order.

All our bassinet linen at The Sleep Store will fit a Cariboo or other 76 x 40cm bassinet. We also have options for bassinets up to 80cm x 40cm.

We have a range of bassinet mattresses in stock and can also make a custom-sized foam bassinet mattresses for you, but please allow 3 weeks for manufacture and delivery.  

Moses Basket Sizes

These come in a range of sizes, generally either 71 x 36cm or 72 x 40cm, which fits The Sleep Store Moses Basket. Please check the individual mattress size of your moses basket as they can be up to 49 cm in width or up to 89cm in length.

You can use any bassinet sheets although most bassinets are square ended rather than the oval shape of a moses basket mattress.

Babu oval bassinet sheets are another good option.

Stokke Mini

The Stokke Mini is an oval shaped bassinet. We recommend the Babu Oval bassinet sheets for this bassinet.

Kaylula Sova Cot

The Kaylula Sova is an oval shaped bassinet that can be adapted to cot and then a toddler bed. The mattress and frame are made in sections to allow the bed to 'grow'. Many of our oval sheets will fit the cot size Kaylula.

Cradle Size

Cradles are more common in Australia than New Zealand, and are basically a large bassinet. These come in a range of different sizes, so please check your specific mattress size before ordering linen.

We recommend the Living Textiles range of specific cradle linen, which is suitable for cradle mattresses up to 47 x 92cm.


NZ Standard Size

This is the old standard size cot in New Zealand and is also called a Euro cot as it is common in the UK.

The NZ standard cot mattress measures 59 x 119cm or 60 x 120cm.

These are very uncommon in NZ now apart from older, handed down cots. While they are called 'standard', they are now far from standard!

We can no longer source any linen specific for this size. Choose any cot linen for an American sized cot and it will fit fine (just the fitted sheet will be a little big and you can tuck in the excess).

Replacement cot mattresses can be ordered in foam only, no innersprung are available in this size.

American Cot Size

This is now the most common size in New Zealand for cots. The measurement is usually 130 x 69cm, with a little variation such as 68 x 129 etc.

All cot linen available from The Sleep Store will fit an American size cot.

We do stock some items for large or Boori cots, which will also fit an American Cot (the fitted sheets will be a little big and the excess can easily be tucked in).

Both innersprung and foam mattress can easily be ordered in this American Cot Size.

Large or Boori Cot Size

This large cot size is much less common in New Zealand but relatively common in Australia.

Please check measurements on linen before ordering, as not all our linen will fit this size.

Boori cot mattresses are usually approx 77 x 132-135cm or variations around that.

All cot sheets from Living Textiles, aden+anais and Babu will fit a large or Boori Cot.

Baby First and American Baby Co sheets will NOT fit a Boori sized cot.

UK Large Cot Size (140 x 70cm mattress) or called UK Cot Bed

This size is very uncommon in NZ and Australia.

Very hard to source linen in this size, click here for all our linen options and use the size or brand filter to find any available options.  Babu cot sheets or sets are the best option (76cm wide, 144cm long and suitable for a mattress up to 17cm deep).

Mattresses are only available in foam. Please enquire if not in stock on our website, as we can easily have this size made for you. No innersprung mattresses are available in NZ in this size, you would need to import from the UK.
