1. The Little Green Sheep Natural Twist Mattress

In search of the best organic cot mattress? Look no further, as it doesn’t get better than The Little Green Sheep Natural Twist. This mattress has a unique two-sided design: one side is amply firm, and the other is a bit more supple. The firmer side of the mattress is great for babies ranging from newborn up to 12 months, whereas the other side is intended for older babies.


Most mattresses on the market tend to suffer from questionable durability, but not Natural Twist, as it’s guaranteed to be your baby’s comfiest companion till 5 years of age. What we admire the most about this mattress is that it’s entirely handmade from all-natural materials, namely natural latex, extremely breathable cotton, hypoallergenic wool, and highly supportive coconut coir.


The combination of these materials makes for an environment where dust mites wouldn’t dare to dwell. What’s more, these are temperature-regulating materials, ensuring your baby is cool and comfortable at all times. Note that high temperature is one of the causative agents of SIDS, and so investing in a mattress that prevents overheating is a brilliant precautionary measure.


The manufacturer also claims that the Natural Twist mattress provides natural fireproofing. This means that chemical fire-retardant sprays were not used in the making of this mattress. It’s also worth noting that the used materials are certified by OEKO TEX. The Natural Twist spans about 70 x 140 cm, and it’s not waterproof, so keep that in mind to prevent damaging the mattress.

All four are quite remarkable!


The Airflow and Essentials models are available in two sizes each: 60 x 120 cm and 70 x 140 cm. Both the Pocket Sprung models, per contra, are only available in the latter size. Each model employs different materials for its construction. The Essentials mattress, for example, features foam and fibrous filling that’s completely free of chemicals, with a core that’s made of polyester.


The Airflow model, on the other hand, flaunts a 3D mesh cover that ensures optimal airflow and proper temperature regulation. Similar to the Essentials mattress, the Airflow model comes with a polyester core that offers supreme comfort and support. The other two models also have their own bells and whistles, so make sure you check them out before making a final decision.

Have you ever heard of plagiocephaly? It’s a disorder that results in a baby’s head looking flattened. It’s a very common and treatable disorder, so don’t be alarmed, but it’s important to know that a lot of mattresses that claim to be baby-specific can actually increase plagiocephaly’s risk. This is why, once again, it’s imperative that you contemplate your selection of a cot mattress.


The Clevamama Clevafoam Support Cot Bed Mattress, as the manufacturer claims, is specially made with the aid of credible academics to preserve the roundness of your baby’s face. The mattress does an excellent job of ensuring ideal spine alignment. Not only that, but it also provides remarkable comfort for your baby’s head, neck, and entire body.

The mattress flaunts 11 cm of thickness to ensure ideal support. And despite being notably thick, the mattress manages to remain very comfy.

Also, to prevent dust mites from setting camp inside the mattress, the core is also covered with lambswool, which happens to be an excellent repellent of dust mites.


Another terrific thing about lambswool is that it serves as a natural temperature regulator that is perfect for allergic babies. The cover is made of organic, soft-touch bamboo, and it’s quite easily removable for cleaning.
