The Cheat Sheet: Waterproof Cot Sheets

5 reviews

This sheet will be your best friend at 2 a.m. after a nappy leak or a spill! The snuggly jersey cotton fitted sheet feels and sounds like a normal sheet but has a clever, quiet waterproof layer hidden underneath, making wet bed changes quick and easy. No need to wrestle with or wash a separate mattress protector. More sleep, less washing! 


Changing the sheet and the mattress protector in the middle of the night when you are tired, bleary-eyed and dealing with a wet, crying baby is no fun. We designed the Cheat Sheet to make changing wet or soiled sheets super quick and easy, so you can get back to bed and enjoy a few minutes of extra sleep! 

  • The fitted sheet is made from a super snuggly, soft and stretchy cotton jersey. This high quality fabric is comfortable for your baby no matter what the temperature or season.  
  • Hidden underneath is a sewn in waterproof protector. You won't even know it's there - the sheet looks, sounds and feels like a normal sheet when it's on your cot, but will prevent any nappy leaks, reflux or spills from getting on your mattress. 
  • No need to replace a separate mattress protector every time your sheets get wet, and also means half the washing! 
  • An alternative to leaving a cloth or pad under baby's head to catch spills - the NZ safe sleep guidelines state there should be no loose items or bedding in the bassinet. 
  • Available in classic white, soft blue or soft pink. 

And here's a trick we call "The Ultimate Cheat" - place two Cheat Sheets on the mattress at a time. When one is wet, just quickly remove and - ta da - a clean sheet is already in place!  

How to Use

  • Place the Cheat Sheet straight on your mattress, with no need for a separate mattress protector. 
  • When the sheet gets wet or soiled, whip it off and pop it in the wash. 
  • The Cheat Sheet is designed to fit a standard NZ Cot size mattress of 69cm by 130cm, however due to the stretch of the cotton jersey and generous skirt and full elastic, it can fit slightly smaller or larger mattresses. Please always ensure our sheets fit your mattress snugly for safe sleep. 
  • The Cheat Sheet some in a matching drawstring bag. We have chosen to leave off our branding so you can re-use this for any purpose - use as a gift bag, to store toys or clothes, to help organise your nappy bag etc. 

Care & Materials

The top sheet is made from 95% cotton with 5% elastane for stretch. The waterproof layer is made from coated PUL, and the sheet has a generous skirting with full elastic for a snug fit. 

  • Please wash with like colours before first use, then check for loose threads and remove if any are found. 
  • Cool or warm machine wash and line dry only.
  • Do not tumble dry, bleach or iron. Tumble drying may damage the elastane, or cause shrinkage. 

Safe Sleep

New Zealand’s safe sleep guidelines have been developed from science and research, and have helped significantly reduce the rates of sudden infant death. Please always follow safe sleep guidelines with your baby. In particular when using our sheets:

  • Please ensure our sheets fit tightly on your cot or bassinet. We are more than happy to accept returns if the sheets are not a snug fit! 
  • The mattress must be firm. Soft mattresses and underlays increase risk of SUDI due to changing the position of baby’s airway (even when they are on their backs), and their face sinking into the surface causing suffocation. Please do not use a padded or puffy underlay or protector under our sheets. 
  • Always put your baby on their back in their bassinet or cot. Babies sleeping on their sides or tummies have a much higher risk of SUDI (sudden unexplained death of infants)
  • Once baby is rolling, swaddles must be removed so they can move freely. 
  • Don’t put anything in their bed that could cover your baby’s face, lift their head or choke them – no toys, pillows, loose bedding, bibs, headbands, bumper pads etc. This includes using a muslin, towel or other cloth under their head to catch spills. 
  • Ensure your baby is at a comfortable temperature. You can check that your baby is warm but not too hot by feeling the back of their neck or their tummy (under the clothes). Baby should feel warm, but not hot or cold.

    Waterproof Sheets

    This is a lifesaver. Baby Spits up from time to time and this has saved my Mattress. Had a leak the other night. All I had to do was take out the cover and I had one ready underneath so make sure to buy 2. Highly recommended. Great service too.

    Love these sheets

    I love these sheets! There’s no need for dealing with a mattress protector and sheets, it’s all in one! Super quick and easy to change. The fabric is so soft too! These days with sleep sacks being the go to option for bedding, top sheets aren’t required and being all in one I.e. no need for a mattress protector, it’s really quite affordable too. I’d say if you have to change them frequently the rule of three is the way to go- one in use, one in the wash and one drying/dry.


    Fantastic product. The sheet contained two nappy leaks and many many vomits/spills. My wee one tends to spill or vomit at least once per nap. The best thing was only washing one sheet rather than mattress protector and sheet. It has saved a lot of washing and therefore sanity. I would certainly recommend to other mums, and suggest purchasing in the rule of three. One in the wash, one on the bed and one ready to go.

    Great product! I was skeptical at the start but am now your biggest fan. My little boy is a constant sweater, every night he sweats through so I am forever washing bedding and airing out the mattress. This sheet has stopped any moisture getting to my mattress and is so much easier to change then a traditional mattress protector that is bulky and can be hard to fit. It is so easy to put on, the stretchiness is a game changer for me. I can strip and change his cot so much quicker. Feels so luxurious, so soft but a nice thickness that you know it will last. I would recommend this to anyone that changes their babies bedding a lot or doesn’t want a bulky mattress protector.
