Cot Mattresses

Cot Mattresses UK – Supportive, Safe & Perfect for Growing Babies

One of the most important nursery decisions you’ll make is choosing the right cot mattress. Your baby will spend a significant amount of time sleeping—up to 16 hours a day in their first year—so it’s vital to provide a firm, safe, and comfortable surface.

At Baby Travel, we offer a trusted selection of cot mattresses UK that meet strict safety standards, support healthy development, and ensure peaceful sleep for babies and toddlers alike.

Why Cot Mattress Quality Matters

A good cot mattress is more than just a soft surface—it should:

• Support proper spinal alignment

• Minimise the risk of overheating

• Prevent dust mite and allergen build-up

• Maintain its shape over time

• Ensure firm resistance for safety

All our cot mattresses are designed with these principles in mind, giving parents peace of mind while their little one rests.

Types of Cot Mattresses We Offer

We cater to a wide range of preferences and budgets:

1. Foam Cot Mattresses

Lightweight and budget-friendly, these mattresses offer firm support and are easy to clean. Many models come with waterproof, wipeable covers—ideal for those early months.

2. Sprung Cot Mattresses

With a layer of springs for added support and durability, sprung mattresses ensure balanced weight distribution and are great for long-term use.

3. Pocket Sprung Cot Mattresses

A more premium option, each spring is individually wrapped to offer tailored support. These mattresses reduce pressure points and grow with your baby, making them ideal for cot beds used up to 4 years.

4. Dual-Sided Cot Mattresses

Two sleep surfaces in one—often a firmer newborn side and a softer toddler side. These versatile mattresses offer extended usability as your child grows.

5. Natural Fibre & Eco-Friendly Mattresses

Made with organic cotton, coconut coir, and natural latex, these breathable and sustainable mattresses are perfect for eco-conscious families. They’re naturally hypoallergenic and free from harmful chemicals.

Mattress Sizes & Fit

Our cot mattresses are made to fit standard UK cot and cot bed sizes, including:

• 60 x 120cm – For standard cots

• 70 x 140cm – For cot beds

A correct fit is crucial for safety. The mattress should be snug with no gaps larger than 3cm around the edges.

Cot Mattress Features to Look For

When choosing a cot mattress, consider these key features:

• Firmness: Prevents suffocation and supports proper posture

• Breathability: Promotes airflow and regulates temperature

• Removable, Washable Covers: Keeps the mattress fresh and hygienic

• Waterproof Layers: Helps protect against leaks and accidents

• Anti-Allergy Properties: Ideal for babies with sensitive skin

• Reversible Use: Some offer different firmness on each side

We ensure our range ticks all the boxes so you don’t have to compromise on your baby’s comfort or health.
