Support Layers

Our cot mattress support unit is provided by natural coconut coir which has been sprayed with natural latex. The latex coating provides a more responsive and progressive support for the coir.

Coconut fibre is incredibly tough yet highly elastic so can provide excellent rebound properties especially for mattresses. Coir is naturally resistant to salt water and perspiration meaning it doesn’t degrade with moisture.

This latex coir support layer is 3750GSM. This mattress is suitable for up to a 2-3 year-old child not exceeding 16kg in weight.

Comfort Layers

This cot mattress is upholstered with Natural lambswool. The 500 GSM layer is incredibly soft, breathable and 100% natural. It acts as a very soft comfort layer for little sleepers allowing breathability and temperature regulation.

Wools main benefit is that it is incredibly breathable allowing it to wick away both moisture and increases in temperature when it is placed against say a warmer sleeper. It has the opposite effect when it is cold, of helping to trap warm air and release heat against a colder body.

As wool is a durable material it also lasts for years compared to synthetic fibres which can break down relatively quickly when flattened.

Upholstery Layers

Our Natural Cot mattress features a 3750GSM coir and latex support layer which gives little sleepers a firm but progressive support.

This is then topped with 500GSM on each side, of pure lambs wool. This gives a soft and breathable comfort layer perfect for delicate sleepers.

The mattress then features a water resistant and hair proof internal cover. So if any accidents occur it protects the core mattress from damage.

It is then covered with a microfibre pinsonic zipped cover. Adding a final soft layer to the mattress. This is machine washable at 60degrees.

We also supply an additional external cover to assist when changing the mattress. We find parents find having a spare cover a god send!

It is a fully turnable cot mattress meaning you can use both sides.

How it will feel?

This cot mattress has been designed to accommodate even the heaviest of newborn babies. It’s firm support unit is ideal for babies who require more support.

Babies require a firmer support as they are less capable of keeping themselves aligned properly during the night. This is because babies are still getting used to movements and are really dependent on their parents to help support them during the day, the same is true of the mattress.

The 100% natural lambs wool topper will add a super soft, breathable comfort layer for your little sleeper.

Cot Mattress Safety

Fire retardancy or FR applies to all mattresses and every product sold in the UK should adhere to these standards. The standards are set by British regulations (BS 5852: 1982 Part II & BS 7177). You can check products by inspecting the FR label. An example of an official label can be seen below and we have a detailed article dedicated to FR in mattresses here.

This ensures that the product won’t combust when either a lit cigarette or a match is dropped onto it. It should smoulder but never ignite, the tests are stringent for good reason. A cot mattress should always carry this label.
