Kids' Bed Size Chart
We always recommend selecting a mattress size and bed frame that allow ample room for your child to grow, to maximise the longevity of the product and prevent your child from sleeping in an ill-suited bed for an extended period.
If you're uncertain where to begin, measuring your child's bedroom can provide a rough estimate of the available space. Then, refer to the mattress size chart below to identify the ideal bed size.
Even if you're not in the market for a new mattress, utilising the mattress size is the most effective way to determine the appropriate bed size for your child. While we have included age ranges as recommendations, keep in mind that every child is unique and may vary slightly from these guidelines.
|Mattress Size (WxL)
|Recommended Age Range
0 - 2 years
Toddler Bed/Cot Bed
2 - 4 years
Small Single Bed
Small Double Bed
What age do kids go into a bed?
For children under the age of 2, we suggest they continue using a cot bed that offers protection while they sleep with its high sides. Toddlers aged between 2-4 years should upgrade to a toddler bed, which lacks high safety rails, but instead has raised sides to reduce the risk of falling out of bed at night.
Low sleepers are ideal for children aged 4 and above because they are easily accessible as they are low to the ground. Mid sleepers and high sleepers are recommended for children above the age of 6 due to their increased height, making them suitable for older children.
Bunk beds should only be used by children over the age of 6 on the top bunk to improve safety, while children over the age of 3 can use the bottom bunk.
When purchasing a kid's bed frame for your child, it's essential to keep the kid's bed size in mind since kids' mattress sizes are not always the same as an adult bed. For instance, a toddler bed requires a toddler mattress, and so on.
How do I transition my toddler to a bed?
Introduce the idea: Start talking to your child about the transition a few weeks before making the actual switch. Explain to them that they will be getting a big-kid bed and how exciting it will be.
Involve your child: Let your child help you pick out their new bedding or choose where the bed will go in the room. This will help them feel more involved in the process.
Gradually make the switch: It can be helpful to start by having your child nap in the new bed for a few days before making the full transition. This can help them get used to the new bed and make the transition less overwhelming.
Make the new bed feel familiar: Use your child's favorite blankets, stuffed animals, and other comfort items in the new bed to make it feel more familiar and comfortable.
Open coil sprung mattress: This type of mattress is a popular choice for children, as it provides good support and comfort. It also tends to be more affordable than other types of mattresses. Look for one with a high coil count and a firm support system.
Memory foam mattress: Memory foam mattresses are known for their comfort and pressure relief. They contour to the body's shape, making them a good option for children who tend to move around a lot during the night.
Latex mattress: Latex mattresses are durable and hypoallergenic, which makes them a good choice for children with allergies or asthma. They also provide good support and comfort.
Hybrid mattress: Hybrid mattresses combine the support of an innerspring mattress with the comfort of a memory foam or latex mattress. They can be a good option for children who need both support and pressure relief.
