Best Kids Beds with Storage Under £400 (UK Guide)

When you're furnishing a new room, costs can add up quick. Choosing the right bed for your child’s room can be tricky, especially when you want to make the most of a smaller bedroom without breaking the bank, and also making sure your little one gets a bed frame they like.

That’s where beds with storage come in. Frames with under bed storage and attached fixtures help maximise space underneath the sleeping area, providing smart solutions for tidying away clothes, toys, bedding, and more—all while keeping floor space clear.

Our team has put together a quick look at some of the most popular types of storage beds for kids and highlight the best options under £400 from the Millie & Jones range.

Why choose beds with storage for kids?

It's simple: beds with storage combine comfort and practicality. From classic wooden bed frames with pull out drawers to ottoman bed frames that lift for hidden storage, these designs help minimise clutter in a child’s bedroom so you can keep the floor clear and take away one more stress.

Storage beds are especially useful in smaller bedrooms or shared rooms where every bit of floor space counts. By using the space underneath the bed, you can reduce the need for additional furniture like toy boxes, shelves, or extra wardrobes.

The best storage bed frames for kids blend function with style, often in neutral tones that suit any décor. Our Millie & Jones storage beds are also easy to assemble, with self-assembly options that are straightforward for most households.

Most popular types of kids storage beds

When it comes to finding the right fit for your child’s room, there’s a wide range of storage bed options to choose from:

• Ottoman storage beds: These beds feature a lift-up base that reveals storage space underneath the mattress. Ottoman bed frames are great for storing bedding, clothes, or seasonal items out of sight.

• Storage beds with built in drawers: Beds with pull out drawers provide easy-access storage space that’s ideal for everyday items.

• Mid sleepers and high sleepers: These designs raise the bed higher off the ground, creating storage space or shelving underneath — or even room for a desk.

• Bunk beds with storage: Bunk beds with built in drawers or shelves help keep shared rooms tidy without adding more furniture.

No matter the bed size—from single to king size—you’ll find storage options that suit your needs.

How to choose the right storage bed for your child’s room

When you're deciding between storage bed frames, make sure to consider the layout of the room and think about how much space is available. Ottoman beds are ideal if you want to hide away storage for larger items, while beds with pull out drawers work well if you need quick access to clothes or toys at a moment's notice.

Think about the height of the bed too. Mid sleepers and high sleepers offer more space underneath, but you’ll want to make sure it’s safe for your child’s age and allows enough clearance on top. For smaller bedrooms, beds with built in drawers or an ottoman base often provide the most space-saving solution.

It’s also worth considering the materials for everything from the frame to the headboard. Wooden bed frames are popular for their durability and classic look, while upholstered ottoman bed frames add a softer touch.

Storage bed tips for maximising space

• Store bedding or seasonal clothes in hidden storage areas to free up wardrobe space.

• Use pull out drawers for everyday items like pyjamas, books, or toys.

• Choose bed storage that reduces the need for additional furniture.

• Look for neutral tones to keep the room feeling open and modern.
