Your guide to buying a kids bed
Just like clothes, shoes and toys, finding the right bed for your growing child can feel like a never-ending game of catch-up. One day their bed’s a perfect fit – the next, their toes are poking out the bottom!
To help make that journey from cot to toddler bed to ‘big kid’ single feel smooth and simple, we’ve pulled together this handy kids’ bed buying guide. Read on to find the right fit for your little one, ensuring they can enjoy a good night’s sleep every night!
When should children transition from a cot to a bed?
One of the toughest parts of watching your child grow up is knowing when to make the move from cot to bed. It’s a big moment – and every child reaches it in their own time.
As a general rule, most children move into a toddler bed around the age of two. However, some may want to stay in their cot for a little longer, while others might be ready to upgrade earlier.
The best approach is to keep an eye out for the signs. If your child is trying to climb out of their cot (or succeeding!) most nights, says they’re uncomfortable, or starts asking for a ‘big bed’, it might be time to make the switch. And if you’re not sure, trust your gut – you know your child best!
What are the different kid bed types?
Every child is different – and so is every bedroom. That’s why we’ve got a wide range of kids’ beds designed to suit all ages, personalities, and spaces.
Cots and toddler beds
Designed to keep babies safe and cosy, cots are perfect up to two years of age. Most feature adjustable sides for easy access and safety rails to stop your little one from rolling out of bed. As they grow, you might move on to a toddler bed – a small single that’s low to the ground and gives them a touch more independence from around age two to four.
Single beds
Once your child outgrows their toddler bed, a single bed is the next big step. Great for children aged four and up, single beds come in a wide range of styles to suit every bedroom, including small single beds with funky themes and character designs. From simple classics to clever storage beds and pull-out trundles, singles offer convenient, compact comfort for your little one.
Bunk beds
Ideal for siblings sharing a room or kids who love sleepovers, bunk beds give you two beds in the space of one. Sturdy, safe, and built with strong frames, bunk beds like our Stompa compact bunk bed offer peace of mind for parents. You’ll also find designs with clever extras such as drawers, shelves or eye-catching different-sized bases, like the Noha bunk bed with double bottom bunk.
Mid sleepers
Mid sleepers, or cabin beds, are single beds raised off the ground with space underneath for handy extras. With guard rails and a ladder for easy access, they’re a great choice for kids who love a little adventure. Many come with pull-out desks or built-in storage – ideal when you want to make the most of every inch of floor space.
High sleepers
Taking things a step further, high sleepers (or loft beds) elevate your child’s mattress to create even more room underneath. Whether you go for a gaming zone, homework desk, or chill-out area, there’s loads of flexibility to make it their own.
Which bed size is best for my child?
Children grow quickly, which means they’ll likely need a few different beds before they reach their teens. To help you make the right choice, here’s a breakdown of common kids’ bed sizes and when they’re best suited.
Cots
Standard dimensions: 120cm x 60cm (3ft 9” x 1ft 9”)
Recommended age range: 0-2 years old
Cots and cribs are designed for newborns and young toddlers, with high sides to stop babies from rolling out. Many feature adjustable mattress levels so you can lower them as your baby grows and starts standing.
Toddler beds
Standard dimensions: 140cm x 70cm (4ft 6” x 2ft 3”)
Recommended age range: 2-4 years old
Ideal for toddlers and pre-schoolers, these small, low-to-the-ground beds are a natural next step after the cot. Without enclosed sides, they offer more freedom while still feeling snug and safe. Plus, they often come in fun, colourful designs your child will love.
Small single beds
Standard dimensions: 190cm x 76cm (6ft 3” x 2ft 6”)
Recommended age range: From 4 years old
Smaller than a standard single, these beds are a great space-saving option – perfect for box rooms or when your little one is ready to move on from a toddler bed.
Single beds
Standard dimensions: 190cm x 90cm (6ft 3” x 3ft)
Recommended age range: From 4 years old
Ideal for older kids, single beds are a versatile choice that’ll last for years. They work well in most bedroom sizes, though some designs – like mid sleepers – might need a slightly longer mattress, so it’s worth double-checking measurements.

What else do I need to consider when buying a kid’s bed?
Even with all the information above, there are certain commonly asked questions about kids’ beds that can really help when choosing the right frame and mattress for your child.
What mattress is good for bunk beds?
When you’re looking for a mattress that’s good for kids’ bunk beds, you need to make sure that the mattress isn’t deeper than the side of the frame and doesn’t cover or extend taller than the side rail.
Many of our kids’ bunk beds are sold with mattresses that fit perfectly into each bunk, offering plenty of support and comfort.
Check the product description of any of our bunk beds for our recommended mattress depth.
However, if you’d like to opt for separate mattresses, some of the best options for bunk beds are medium-firm or firm mattresses. This is because the support they provide helps to maintain the integrity of a bedframe, both by discouraging bouncing on the bed and helping to absorb a sleeper’s weight.
What mattress firmness is best for my child?
A medium-firm mattress is often the sweet spot for little ones. It offers enough support for growing bodies, helps limit tossing and turning, and makes it that little bit less tempting to bounce on the bed. For more information, head over to our kids mattress buying guide or read our more general mattress buying guide.
What if my child frequently has sleepovers?
If you’re expecting more than one sleeper in your child’s bedroom, we’d highly recommend bunk beds. From single bunk beds to double bunk beds, these kids’ beds provide sleeping spaces for multiple kids, without taking up more square footage than a single bed frame.
You could also choose a trundle bed, as the pull-out sleeping space can comfortably accommodate a smaller guest sleeper.
What if my child wets the bed?
Accidents can happen throughout the night, but luckily there are ways to prepare. A washable mattress protector helps to protect the bed and the mattress, as do washable bed pads. Both ensure that your child’s mattress stays protected and lasts beyond the bed wetting phase.
Should I consider kids’ beds with additional features?
Some of the most useful additions to a kid’s bed are extra storage solutions or even additional sleeping spaces. This includes children’s single beds with pull-out drawers or shelving areas, kids’ bunk beds, and single beds with trundles.
These additions don’t impact the safety or comfort of a kid’s bed but provide plenty of extra storage space to help declutter a kid’s room. Or they grant extra sleeping spaces, without imposing on the available floor space of a bedroom.
