### UK Safety Guidelines for Baby Mattresses According to The Lullaby Trust and standard British Safety regulations (BS 1877-10:2011):
- Firm and Flat: The mattress must be completely flat with no sagging or soft cushioning. - Snug Fit: There should be no large gaps between the edges of the mattress and the cot frame (gaps should be under 3cm). - Thickness: Newborn mattresses should generally be at least 8cm to 10cm thick. - Waterproof Cover: Always use a clean, intact waterproof cover to keep the core hygienic.
