Quite a few reports of the mattress having a strong ‘chemical’ smell when brand new. (This could be just simply be from the manufacturing process and storage, and something that will dissipate after a short while of airing out.

Soft, supportive and anti allergenic. The core is made of foam, which is reflected in the low price. It isn’t going to last forever, but will do the job and it is replaceable after a lot of heavy use (thanks to the low price.)

Kit for Kids Kidtex 70 x 140cm Cot bed Mattress – Whitekit for kids kidtex mattress

An affordable and well built mattress from Kidtex. We like the double cone springs combined with the foam layer. The springs ensure that the mattress gives proper postural support and increases the longevity of its use and the foam layer gives a soft and comfortable finish for baby or little one.

Finished with a water repellent outer layer that has a zip fastening for ease of use, it seems that this cot bed mattress ticks all our our checklist boxes.

Although there are no natural fabrics, this mattress has proved to be a winner by its other values, being hypo-allergenic and anti- microbial – something that is not always available in cheaper mattresses.

Everything about the Kit for Kinds Kidtex mattress is geared towards offering the most amount of quality for money and to give your little one the best sleeping environment possible.

Why we would choose this mattress:

A mattress undoubtedly created with baby and child’s needs in mind. Giving parents the peace of mind that they are giving their little ones the very best start.

Why we would not choose this mattress:

The only reason we can think of is because if contains no natural materials, they are all synthetic. However that would add a higher price tag to the mattress, so we are struggling to put it as a reason!

Baby Cot Bed Mattress – 140cm x 70cm Pocket Sprung Mattressbaby pocket sprung mattress

A great middle of the range cot bed mattress with pocketed springs for maximum comport.

The mattress has a stockinette layers, to reduce friction on the surface of the mattress making it last longer. When visible, this layer looks weird but having it there is super useful and it even makes it easier to put the outer layer back on.

There is no water repellent or waterproof layer, which is the only thing to let this mattress down.

Features What is is made of? Cleaning Warranty
Individual pocket springs for optimum comfort and support. Pocketed springs Washable removable cover with zip fastening None mentioned

Why we would choose this mattress:

Super comfortable and well made fore the money, To get the best of both options, breathable foam and individual pocketed springs is certainly a bonus!


Why we would not choose this mattress:

There is no water repelling fabric used, which means having to buy a separate protector.

It might also be worth mentioning that there are a couple of reviews for this mattress where buyers have complained that after taking the mattress out of the packaging for the first time, it smells of strong chemicals. But again, (like the other mattress, with the same problem reported) we think the smell may be something that disappears after being aired out.

Obaby Sprung 140x70cm Cot Bed Mattress – White

A really pretty mattress with surface detail. We love the side zip which makes washing the cover a doddle and the fact that this is first mattress we have included (in price order or cheapest to most expensive) that actually has a brushed cotton surface. We know the longevity of good cotton, wash after wash. The breathable cover also helps with air movement and heat dissipation.

The cheapest mattress we have discovered that comes with a free five year guarantee too.

We like the Obaby mattress mostly because of the high tensile coil springs, a long lasting and supportive core. That paired with a strong and soft foam layer on top and below the springs ensures the most comfortable experience possible for baby or child.

This mattress has a choice of Foam , Natural Coir, Pocket Sprung or a Spring centre.

Features What is is made of? Cleaning Warranty
Softly quilted and breathable cover High tensile coil springs for extra support Water resistant cover machine washable Free 5 year guarantee

The Mattress, in all variations is quite thin. It is officially 10cm but it looks and feels quite thin.

Mamas & Papas Sprung Cot Bed Mattress

A mattress that does everything we want it to and looks beautiful at the same time.

It is packed with luxury features and a sturdy, well built set of open springs.

When looking inside the mattress, it looks well made and very well padded with a generous layer of cushioning foam on the top and bottom.

Underneath the outer layer is a water repellent layer that can still be used even when the top layer is in the wash. Perfect for night time accidents when you and you child just want to get back to sleep!

This mattress has been designed to assist parents with babies and parents with children in different ways. One side of the outer layer has a luxurious 3D fabric, for better air circulation, breath-ability and heat distribution, (especially for babies).

The other side of the mattress actually has a waterproof fabric, especially useful when older children are toilet training, and thankfully, the waterproof surface is vapour permeable, which makes the bed significantly more comfortable for children, by reducing sweating and allowing air and heat to pass through the waterproof surface.

The part we really love is the inside. One side is specially designed for babies, with supportive coconut fibres, acting as thousands of tiny springs. This gives you baby all the support he or she will need and the freedom from chemicals or synthetic materials.

The other side of this unique mattress is specially designed for older children, being made from a  supportive strong and long lasting natural latex.

Why we would not choose this mattress:

This mattress is in no way waterproof or water resistant. It has to be used with a mattress protector (bought separately). When you are investing in such an expensive mattress, looking after it becomes incredibly important! We wish there was one included, but sadly there is not.

It also cannot be used with sleeping sensor mats or sleeping aids.

Top Luxury Mattress


The Little Green Sheep 70cm x 140cm Twist Natural Latex Cot Bed Mattress

We struggled to pick winner between the John Lewis one and the Little Green Sheep mattress.

At nearly half the price of the Little Green Sheep one, the John Lewis ticks all of our boxes and more. If the high cost of the Little Green Sheep one is an issue then we would certainly give our vote to the well designed, well built and great at everything John Lewis one.

However, as this is a top luxury mattress vote, we feel that what the Little Green Sheep Natural Twist combed mattress has to offer is unique, special and and investment worth making. This really is our best cot bed mattress.

It of course, ticks all of our boxes and then some.. we are astonished at the inner materials of coconut fibres and natural latex. How better to sleep than on something natural, supportive and in a pure and healthy environment, free from chemical fire retardant sprays, adhesives. (Found in almost all other mattresses) (Don’t worry, this doesn’t mean the mattress isn’t fire retardant. The wool acts as natural fireproofing.

We love this mattress so much, with all of its unique qualities. It is definitely and investment that will pay off over the years of use.
