What Kind of Mattress is Best for a Child?
Choosing the right mattress type depends on your child's age, sleeping habits, and any specific needs they may have. Our collection of kids’ mattresses include:
- Kids' Memory Foam Mattresses - These contour to your child's body shape, providing pressure relief and proper spinal alignment. Perfect for children who need extra comfort or have growing pains.
- Kids' Pocket Sprung Mattresses - Featuring individually wrapped springs that work independently to support your child's movements throughout the night. Great for active sleepers who change positions frequently.
- Kids' Open Coil Mattresses - Traditional spring mattresses that offer firm, reliable support at an affordable price point. A budget-friendly choice that doesn't compromise on quality.
All our children’s mattresses are made with non-toxic materials and are hypoallergenic, ensuring a safe and healthy sleep environment for your child. For guidance on selecting the best option, read our guide to choosing a mattress.
Kids' Mattress Sizes and Age Suitability
Selecting the right mattress size ensures your child has enough room to sleep comfortably as they grow. Here's a breakdown of available children mattress sizes:
- Cot Mattresses (60 x 120 cm or 70 x 140 cm) - Suitable for newborns to approximately 2-3 years old. These fit standard cot beds and provide a safe, snug sleeping space for babies.
- Toddler Mattresses (70 x 140 cm) - Perfect for the transition from cot to bed, typically for ages 2-4 years. The smaller size helps young children feel secure in their new bed.
- Kids’ Shorty Mattresses (75 x 175 cm) - Ideal for smaller bedrooms or younger children aged 4-8 years who don't need a full-length bed yet. These space-saving kids’ mattresses work well in compact rooms.
- Kids’ Small Single Mattresses (75 x 190 cm) - Narrower than standard singles, these kids’ mattresses suit children aged 5-10 years in tight spaces while still offering sufficient length.
- Kids’ Single Mattresses (90 x 190 cm) - The most popular choice for children aged 5 years and up. This size provides ample space for growing kids and fits most standard children's beds.
- Kids’ Small Double Mattresses (120 x 190 cm) - Suitable for older children and teenagers who need more space or for siblings sharing a bed. This size offers extra width for comfort.
- Kids’ Double Mattresses (135 x 190 cm) - Ideal for older teenagers or for siblings sharing, providing generous width and comfort.
- Kids’ King Size Mattresses (150 x 200 cm) - The largest size in our kids' range, suitable for teenagers who want maximum space and comfort.
In our children’s mattress collection, you can also find single, small double, and double continental sizes. These offer 10cm extra length, perfect for taller children or those who need more growing room.
Before purchasing, measure your child's current bed frame and room space. It's also worth considering how long you want the mattress to last, as choosing a slightly larger size can accommodate growth spurts. For more detailed sizing information, check our bed and mattress size guide.
What Firmness of Mattress is Best for a Child?
Mattress firmness plays a significant role in your child's comfort and spinal health. Here's what works best for different ages:
- Toddlers and Young Children (2-5 years) - Firm to medium-firm mattresses are recommended. Firmer support helps with proper spine alignment and reduces suffocation risks. Young bones need solid support as they develop.
- School-Aged Children (6-12 years) - Medium-firm mattresses strike the right balance. They offer enough support for growing bodies while providing comfortable sleep. This firmness accommodates changing needs as children grow.
- Teenagers (13-18 years) - Preferences vary at this age. Medium to medium-firm typically works well, though some teenagers may prefer slightly softer options, especially if they're heavier. Consider their sleeping position and personal comfort preferences.
Our medium-firm mattresses are the most popular choice for children, offering versatile support across different ages and sleeping styles. If you're unsure, visit our West Yorkshire showroom where your child can test different firmness levels in person.
What to Consider When Choosing a Kids’ Mattress
Age and Development - Younger children, particularly toddlers and those under 5, need firmer mattresses to support developing bones and prevent suffocation risks. As children grow older, their preferences may shift towards slightly softer options.
Sleeping Position - Side sleepers benefit from memory foam that cushions shoulders and hips. Back and stomach sleepers need firmer support to maintain proper spinal alignment.
Allergies and Sensitivities - If your child has allergies, look for hypoallergenic materials like natural latex, organic cotton, or certified memory foam. Avoid materials that trap dust mites or moisture.
Breathability - Children tend to sleep warmer than adults, so choose mattresses with good airflow. Pocket sprung mattresses naturally offer better ventilation, while memory foam options with gel infusion or open-cell technology help regulate temperature.
Durability - Kids can be tough on their beds. Look for mattresses with strong edge support and robust construction that can withstand jumping, bouncing, and general wear.
Safety Standards - All our mattresses meet UK safety standards, including fire safety regulations and are free from harmful chemicals.
How Often Should You Replace a Kids’ Mattress?
Children's mattresses typically need to be replaced every 5-7 years, although this timeframe depends on the mattress's quality, usage, and your child's growth. If you see visible wear and tear such as sagging or lumps, or if your child’s feet hang off the end or they’re waking up complaining, it’s time to size up or get a new mattress.
When you're ready to upgrade, read our guide on how to dispose of an old mattress for the best disposal methods. You might also find our article on how often you should change your mattress helpful for planning future replacements.
How Can I Ensure My Kids’ Mattress Stays Clean and Lasts Longer?
Use a waterproof mattress protector from day one to guard against spills and accidents. Vacuum the mattress monthly to remove dust and allergens. Rotate it every 3-6 months to prevent uneven wear. Clean spills immediately with a damp cloth and mild detergent, then let it dry completely. Wash bedding weekly in hot water. Ensure proper ventilation by removing bedding during the day. These simple steps significantly extend your mattress's lifespan while maintaining a hygienic sleep environment.
