Cot Bed Mattress Reviews

Mother Nurture Classic Spring (Editor’s Choice)

The Mother Nurture Classic Spring Cot Bed Mattress is one of the best foam mattress options for your newborn baby. 

It has a super smooth quilted surface on top of the foam that is comfortable and supportive, so that will allow your baby to have a relaxing night’s rest. The sturdiness of this cot mattress is ideal for the newborn baby and also the infant.

There are two layers of nursery-grade foam around the high tensile springs for ultimate comfort. Also, this foam is designed to be dent-resistant to keep the shape of the mattress. With durability in mind, the cot bed mattress also has bound sides to help increase resilience.

Furthermore, the Mother Nurture Classic Cot Bed Mattress has been designed to increase awareness of dangerous chemicals, so this cot mattress uses foam free from organophosphate flame retardants.

There is a robust inner waterproof liner for hygiene. If there are any liquids on the cot mattress, this layer will prevent them from seeping through to the mattress’s core. Also, this mattress is double-sided, which increases the life of the mattress even longer! The cover is super soft, removable, zipped, and machine washable.

Meanwhile, some customers have said that it may have a strong chemical smell when you first buy the mattress; however, this smell should disappear after airing the cot mattress out for a few hours. Because cot bed mattresses are usually quite firm due to the level of support that a newborn needs, some customers have said that this cot mattress is firmer than they wanted.

  • Robust waterproof layer
  • A durable and resilient material
  • Double-sided


  • There may be a chemical smell during the first time of use
