What to Think about when Choosing a Kids' Mattress?

Choosing a mattress for your child isn't just about fluffy comfort; it's about building a foundation for healthy growth. To complete your hunt successfully, let's explore the key factors to consider:

Firmness Levels

While selecting a mattress, choosing its firmness according to your child’s age is important to ensure their comfort. Let’s have a look at how to select one:

  • Infants & Toddlers (0-3 years old): Firmness is your best partner when selecting an infant mattress. A firm mattress reduces the risk of SIDS.
  • Preschoolers & School-aged Children (4-12 years old): Growing bodies need growing support! Medium-firm mattresses offer the perfect balance, keeping their spines aligned. Also, consider edge support to prevent tumbles and keep adventurers tucked in.
  • Teenagers (13-18): Involving your teenagers in the mattress hunt is important! Let them test different firmness levels to discover their comfort zone. You can also consider their preferred sleeping positions – side sleepers might appreciate a softer surface, while back sleepers may need a firmer mattress for optimal spinal alignment.

Mattress Types

Kids' mattresses are built with different materials to cater to their various sleeping needs. Here are some common types that you may consider:

  • Innerspring: The classic choice, offering good air circulation and bounce. Though, it may not conform as snugly to your child's curves.
  • Memory Foam: Memory foam relieves pressure and hugs the body but can trap heat. Latex foam offers similar comfort with better breathability, making it a warm sleeper's dream.
  • Hybrid: The best of both worlds! Combines innerspring support with foam comfort layers for a balanced sleep experience.

Allergies and Hypoallergenic Materials

Kids are more vulnerable to allergies than adults, and their growing immune systems can get easily irritated by typical allergens found in mattresses. These allergens can include:

  • Dust mites: Creatures that live in dust and feed on dead skin cells.
  • Mold and mildew: They can thrive in moist or humid environments, such as within the mattress.
  • Latex: Some mattresses contain a naturally occurring material that some individuals may be allergic to.

What You Can Do?

To tackle allergies, here are some options you can use:

  • Hypoallergenic materials: Look for mattresses made from dust-mite-resistant fabrics and fillings such as encasements or wool. Also, select breathable items that do not trap moisture and mold.
  • Waterproof covers: These protect against spills, accidents, and dust mites in search of a moist environment.
  • Regular Cleaning: Regularly vacuum your mattress whenever possible and allow it to air. Wash covers and bedding with hot water to eliminate allergens.

Size and Fit

In the UK, choosing the right mattress size for your child isn't just about comfort; it's about ensuring proper sleep posture and space for growth. Here are some size considerations to look for:

  • Cots and cribs for newborns and infants should be a close fit size-wise to prevent babies from getting limbs or heads stuck between the mattress and bars. The mattress should be less than 15 cm thick.
  • Toddler beds and mattresses for ages 1-3 should allow for growth. Recommended mattress sizes are 140 x 70 cm. Depth should be 10-12 cm.
  • Children's single beds for ages 3+ often use a standard 90 x 190 cm single mattress. However, ‘mid-sleeper’ beds with an underbed may use a shorter 140 x 70 cm mattress. Depth is typically up to 18cm.
  • Bunk beds should have appropriate mattresses for upper and lower beds so children cannot fall out of bed. Guard rails provide added safety. Lower bunk mattresses are often 140 x 70 cm.
  • When choosing mattress size, allow 20 cm length growth and consider the child's height and weight over the next few years.

Durability and Safety

When selecting a mattress, balancing between quality and budget is not easy. But it is achievable if you use the following tricks:

  • Set realistic expectations: Quality kids' mattresses have a costly price tag. Specify your budget and explore choices within that cost bracket. Keep in mind that quality does not necessarily mean expensive.
  • Search alternatives: Try online shops or discount stores that sell cheap stuff of some good brands. Seek sales and clearance promotions to find a steal.
  • Second-hand Option: A second-hand mattress can also be cheap and effective, but only if it is in good condition and safe.
