Single Bed for Kids, Teens, or Adults: What to Consider

Choosing a single bed might seem straightforward, but the “right” choice actually depends a lot on who will be sleeping on it, how long it will be used, and what the room allows. A single bed can be perfect for one person — but in some cases, a double bed might make more sense. 

Whether you’re buying for a child, a growing teen, or an adult, here’s a simple guide to help you make the best decision. 

Who is the bed for? 

For Kids 

A single bed is usually the ideal next step after a toddler bed or bunk bed. It gives children enough space to sleep comfortably without overwhelming a small bedroom. 

When choosing for kids, think about: 

• A sturdy and safe bed frame 
• A supportive, comfortable mattress 
• A bed height that is easy for them to climb in and out of 

If your child is likely to use this bed for many years, it’s worth investing in a good-quality mattress now so you don’t need to replace it too soon. 

For Teens 

Teenagers often spend more time on their beds — sleeping, studying, relaxing or watching shows. Because of this, comfort and support become even more important. 

Consider: 

• Proper spinal support from the mattress 
• A style that suits their room and personality 
• Space-saving options like storage bases 

Some teens are happy with a single bed, but others prefer a bit more room. In that case, a three quarter or double bed can be a great upgrade, giving them extra space to stretch out while still fitting in most bedrooms. 

For Adults 

A single bed is a practical choice for guest rooms, smaller bedrooms, or apartments. It works well if space is limited or if the bed is mainly for occasional use. 

However, if the room allows, many adults prefer a double bed for everyday sleeping, as it offers more space and comfort — especially for restless sleepers. 

If you’re buying a single bed for an adult, also consider: 

• Mattress firmness and support 
• Weight capacity of the base 
• Whether an extra-length single might be needed for taller sleepers 

Single vs Double: Which should you choose? 

Here’s a simple way to think about it: 

Choose a single bed if: 

• The room is small 
• It’s for a child or single sleeper 
• You want to maximise floor space 

Consider a double bed if: 

• The sleeper wants more space 
• The room can comfortably fit it 
• It may be used by a teen or adult long-term 

If you’re unsure, you can always start with a single and upgrade later — or go straight for a double if space allows. 

The Mattress Makes a Big Difference 

No matter which bed size you choose, your mattress plays the biggest role in comfort. 

Think about: 

• Firm, medium, or soft comfort level 
• Foam, pocket spring, or hybrid construction 
• Durability and support  

A good mattress can improve sleep quality and make any bed — single or double — feel much more comfortable. 

Bed Base and Frame Matter Too 

Your bed isn’t just about the mattress. The base and frame are just as important. 

Ask yourself: 

• Do you want a metal or wooden frame? 
• Would storage underneath be useful? 
• Do you want a headboard for comfort and style? 

A strong base helps your mattress last longer and feel more supportive. 

Room Size and Layout 

Before buying, take measurements of your room and think about how much space you want left over for other furniture. 

A single bed is great for compact rooms, but if you have the space, a double bed can make the room feel more complete and comfortable. 

A standard single bed measures 91cm wide, a three-quarter bed measures 107cm wide, and a double bed measures 137cm wide, with a standard length of 188cm or extra length of 200cm available. 

Final Thoughts 

A single bed is practical, versatile, and space-saving — perfect for kids, teens, or adults in smaller rooms. But if space allows and comfort is a priority, a double bed is always worth considering.
