The Complete Guide to Choosing Your Child's First Bed

Moving from a cot or toddler bed to a "big bed" is one of those milestones that sneaks up on you. One week your little one is still safely tucked behind cot bars, and the next they're climbing out on their own, ready for something new. It's exciting, but it can also feel like a lot of decisions all at once. What size do you need? Is it safe? Will they even sleep in it?

At Crazy Price Beds, we've helped families across the UK make this move for years, so we know the questions that come up again and again. This guide walks you through everything worth thinking about before you buy, so you can choose a bed your child will actually love sleeping in.

You'll find our full range in one place in our kids' beds page, organised by style and size to help you compare options side by side.

How do you know they're ready?

There's no set age when a child is "ready" for their first proper bed. Some children make the switch as early as two, others closer to four or five. A few signs tend to show up around the same time though:

• They're climbing out of the cot, or trying to
• They've outgrown the cot in size
• They're showing interest in a "big kid" bed, especially if a sibling or friend has one
• Potty training is underway, and getting in and out of bed easily matters more

None of these need to happen all at once. If even one or two apply, it's usually a good time to start looking.

What to think about before you buy

Room size and layout

Measure the space before anything else. A single bed is the standard choice for most children's rooms, but if the room is on the smaller side, a trundle bed or a low Montessori floor bed can free up valuable floor space for toys and play.

Safety first

For younger children, a low-to-the-ground bed reduces the risk of injury if they roll out during the night. This is one of the main reasons Montessori floor beds have become so popular with parents of toddlers moving out of a cot for the first time. If you're considering a bunk bed, most guidance suggests waiting until your child is at least six, and always choosing one with secure guardrails on the top bunk.

Storage

Bedrooms fill up fast. A bed with built-in underbed storage can be a genuinely practical choice, giving you somewhere to tuck away spare bedding, toys, or out-of-season clothes without needing extra furniture.

Involving your child

Where you can, let your child have a say. Whether that's picking the colour, the style, or a fun theme, giving them some ownership over the choice makes the transition feel like something exciting rather than something happening to them.

Types of kids' beds to consider

There's a wide range of options out there, and the right one usually comes down to your child's age, your room size, and what matters most to your family.

House beds and cabin beds. These have become a firm favourite for younger children moving into their first proper bed. With a low frame and a cosy, den-like feel, a house bed can make the switch from cot feel less daunting, since it still feels small and secure rather than like a big, open bed.

Princess and themed beds. For children who love a bit of imagination at bedtime, a themed bed can make all the difference. Bedtime becomes something to look forward to, not something to fight against.

Bunk beds. A practical choice for shared rooms or growing families. Bunk beds make the most of vertical space, though they're best suited to slightly older children who can safely use a ladder and sleep securely on a top bunk.

Trundle beds. Perfect if you regularly have sleepovers, or simply want the flexibility of an extra bed that tucks away when it's not needed. Trundle beds are also a smart choice if you're short on space but still want the option of a second sleeping spot.

Montessori floor beds. Low to the ground and designed with independence in mind, these are ideal for toddlers taking their very first step out of the cot. A floor bed lets your child get in and out on their own, building confidence alongside a good night's sleep.

Beds for older children and teens. As children grow, their needs change again. If you're planning ahead, our range of teen beds offers styles that grow with them, from simple, grown-up frames to designs with a bit more personality.

Making the transition easier

However, ready your child seems, the first few nights in a new bed can take some adjusting. A few things that tend to help:

• Keep familiar bedding, a favourite blanket, or a well-loved toy close by
• Stick to the usual bedtime routine as much as possible
• Let them help set up the room, even in a small way
• Be patient. It might take a week or two before it feels normal.

FAQ's

What size bed does my child need first?
For most children moving out of a cot, a standard single bed (3ft) is the right first step, giving them plenty of room to grow into over the coming years. If space is tight, a low-to-the-ground option like a Montessori floor bed is usually still built to single mattress dimensions, so sizing stays the same even if the frame looks different.

Are bunk beds safe for young children?
Most guidance recommends waiting until your child is at least six before using the top bunk, with secure guardrails in place at all times. For younger children who still want the fun of a bunk-style room, a trundle bed offers a similar shared-space feel while keeping both sleeping levels close to the ground.

Do I need a special mattress for my child's first bed?
Not typically. Most first beds, whether that's a house bed, a cabin bed, or a standard single frame, take a regular single mattress. The main thing worth checking is firmness, since a supportive mattress matters more for a growing child than for an adult.

Our final word

Choosing your child's first bed doesn't need to be complicated. Think about their age, your space, and what will make bedtime feel safe and familiar, and the right option tends to become clear. And with prices that won't stretch your budget, you can make this milestone feel special without any of the usual retail markups.
