Serena Cot Bed FAQs
Is a mattress included?
No, our Serena Cot Bed does not come with the mattress. The mattress size required is 70 x 140cm, but due to the unique curves of the Serena Cot, a standard mattress may not fit. We recommend purchasing the bespoke Serena Cot Bed Mattress.
Don't forget to pick up the fitted sheets too!
What is the age range of the Serena Cot Bed?
The Serena Cot Bed is designed to grow with your child from birth up to 5 years old. With the Junior Bed Extension (sold separately) it can be used up to 7 years old
How many different 'stages' does the Serena Cot Bed have and what are they?
The Serena Cot Bed converts through multiple stages: Cot Bed High Mattress (0-6 months), Cot Bed Low Mattress (6 months - 3 years), Toddler Bed (3-4 years), First Bed (4-5 years)
When do I adjust the mattress height of my Serena Cot Bed?
It is recommended to use the Cot Bed with the mattress in the higher position until your baby begins to roll over or pull up, usually at around 6 months old. Once you notice these signs, it is recommended to lower the height of the mattress.
How do I adjust the mattress heights on my Serena Cot Bed?
The Serena Cot Bed features a dual mattress height adjustment. You can lower the mattress height as your baby grows and becomes more active. Follow the steps in the instruction manual to find out how to lower the mattress height
What age do I transition the cot to the toddler bed and first bed modes?
This will depend on your child. If they are asking to move to a "big bed" or you feel they are ready to do so, the toddler bed provides a safe, familiar transition stage. Adding the Serena Toddler Rail (sold separately) can give extra security and piece of mind.
What makes the Serena Cot Bed unique?
Our Serena Cot Bed can be converted from a bedside crib (add-on sold separately) to a junior bed, growing with your child from day one up to 7 years old. The cot bed also stands out due to its unique contoured design with soft flowing lines, creating a serene and cosy sleep space for your child. It is also made to stand the test of time, crafted from solid birch wood and is fully safety certified.
The wood construction is described as eco-wood, low VOC and formaldehyde safe. Do your products contain formaldehyde?
All our items and materials are tested to meet the highest global standards and these tests include ensuring that all materials are baby-safe without any harmful chemicals.
Formaldehyde is a natural gas found in all wood and every piece naturally contains some very very small level of formaldehyde. No wooden furniture can actually claim to be 100% formaldehyde free but our Cot is 100% true/solid wood that is proven to have the lowest level of formaldehyde vs MDF or Chipboard variants.
