Teen Mattress Buying Guide

How to choose a mattress for a teenager

• Age and growth stage: Teenagers are often still growing, which means their bodies need proper support to develop healthily. A 13-year-old's needs may differ from those of a 17-year-old, especially if they're going through a growth spurt. Most teenagers can use the same mattresses as adults, so you're investing in something that'll see them through to university and beyond.
• Size and space for growth: Your teenager might fit comfortably on a single bed now, but will they in a year's time? Teenagers can grow surprisingly quickly, and there's nothing worse than waking up with your feet hanging off the end of the bed.
• Weight and body support: Teenagers' bodies are still developing, which means proper spinal alignment and support are crucial. A mattress that's too soft won't provide adequate support for growing bones, while one that's too firm might feel uncomfortable.
• Sleeping position matters: How does your teen sleep? Their preferred position makes a real difference. Side sleepers need softer support, back and front sleepers need firmer support. Read more in our guides: sleeping on your side, sleeping on your back, and sleeping on your front.
• Personal preference: Your teenager is the one who'll be sleeping on it every night. Get them involved in the decision. Bring them to the store, let them try different mattresses, and actually listen to their feedback.
• Bedroom space: Measure carefully before you commit. There's no point buying a double mattress if it's going to completely dominate a small bedroom, leaving no space for a desk, storage, or even walking around comfortably.

What is the best type of mattress for teenagers?

There's no single "best" mattress type - it depends on your teenager's needs, preferences, and budget. Here are some popular options to choose from:

Can teenagers use orthopaedic mattresses?

Yes, if they need extra support. Orthopaedic mattresses are particularly beneficial for teenagers with back problems, poor posture, or those who are heavier or taller. However, they may feel too firm for lighter or younger teens.

How firm should a teenager’s mattress be?

A teen’s mattress should be between medium and medium-firm. This provides enough support for growing bodies whilst offering sufficient pressure relief for comfort.

Here's a more detailed breakdown:

• Soft (1-3 out of 10) - Soft mattresses don’t provide adequate support for growing spines and can lead to poor posture.
• Medium-soft (4-5 out of 10) - Suitable for lighter teenagers (under 50kg) who sleep on their side. Offers good pressure relief without sacrificing too much support.
• Medium (5-6 out of 10) - The Goldilocks zone for most teenagers. Balances support and comfort effectively. Works well for combination sleepers.
• Medium-firm (6-7 out of 10) - Ideal for average to heavier teenagers, back sleepers, and those needing extra support. Still comfortable but with more structure.
• Firm (7-8 out of 10) - Best for heavier or taller teenagers, stomach sleepers, or those with specific back support needs. Firm mattresses can feel uncomfortable for lighter teens.
• Very firm (9-10 out of 10) - Very firm mattresses are usually too hard for teenagers unless specifically recommended for medical reasons.

When in doubt, go for a medium mattress. These accommodate most body types and sleeping positions, and they're what most teenagers find comfortable.

What size mattress is best for teenagers?

Size depends on several factors: bedroom space, your teenager's height, budget, and whether they're likely to grow significantly in the near future.

Single mattresses

Replace pillows every two years minimum. Measuring 90cm x 190cm, these are ideal for younger teenagers, smaller bedrooms, shared rooms, or when the budget is tight. While these are space-saving, affordable and easy to find bedding for, they can feel cramped for taller or older teens, with limited space for stretching out.

Euro single mattresses

The same size as a single mattress, but with an additional 10cm in length. Great for taller teenagers who need extra leg room but don’t have the space for a wider bed.

Small double mattresses

Also known as 4’0’’ mattresses, these measure 120cm x 190cm and are great for older teenagers, average-sized bedrooms, or those who want more space without going full double. With extra wiggle room, these are a good compromise between space and practicality, and great for sleepovers.

Double mattresses

The most popular size for teenagers, measuring 4’6’’ or 135cm x 190cm. This size is ideal for older teenagers with larger bedrooms, those who appreciate their personal space, or teens preparing to head to university soon. Double mattresses offer plenty of room to sprawl, whether you’re a teen, a guest staying over, or the perfect size to work for adult life, too. The only con for this size is that it can take up significant bedroom space and may overwhelm smaller rooms.

What is a good mattress for a 12-year-old?

A 12-year-old typically needs a medium-firm mattress that provides good support for their growing body, whilst offering enough comfort for restful sleep.

At this age, children often experience growth spurts and increased physical activity, making proper spinal support crucial. Look for:

• Medium to medium-firm support - Balances comfort with the support growing bodies need
• Durable construction - Will last through the teenage years
• Hypoallergenic materials - Important for children with allergies
• Removable, washable covers - Practical for inevitable spills and accidents

A quality pocket-sprung or hybrid mattress typically works well for this age group, offering balanced support that is neither too firm nor too soft.

What is a tween mattress?

"Tween mattress" isn't an official category, but it refers to mattresses suitable for pre-teens and young teenagers (roughly ages 10-14). In reality, most tweens can use standard adult mattresses, particularly single or small double sizes with medium firmness.

Teen Mattress Budget Guide

Let's talk money. Teen mattresses span a wide price range, and whilst you don't need to spend a fortune, investing in quality makes sense.

• Budget range (£200-£400): Decent quality mattresses that'll do the job. Look for basic pocket sprung or foam options.
• Mid-range (£400-£700): Better quality materials and construction. These mattresses often come with longer warranties and will last through the university years.
• Premium range (£700+): High-quality mattresses with advanced features like gel-infused memory foam, luxury pocket spring counts, or hybrid designs. Worth it if your teenager has specific needs or you want something that'll last for years.

Remember: a good mattress is an investment in your teenager's health, development, and daily wellbeing. Better sleep means better concentration, mood, and physical growth.

Teen mattress care tips

Getting your teenager to look after their mattress might feel like an uphill battle, but these simple habits will extend its life significantly:

• Rotate regularly: Rotate the mattress 180 degrees every 3-4 months to prevent uneven wear. Make it part of the routine - perhaps when the clocks change or at the start of each season.
• Use a mattress protector: This is non-negotiable. A waterproof, breathable mattress protector guards against spills, sweat, and general teenage chaos. Much easier to wash a protector than clean an entire mattress.
• Air it out: Pull back the duvet and let the mattress breathe for 20 minutes each morning. This helps moisture evaporate and keeps the mattress fresh.
• Vacuum regularly: A quick vacuum every few weeks removes dust, skin cells, and allergens. Use the upholstery attachment on your vacuum cleaner.
• Deal with spills immediately: Blot (don't rub) spills with a clean cloth. For stubborn stains, use a mild detergent solution. Let it air dry completely before making the bed.
• Follow weight guidelines: Most mattresses have recommended weight limits.

How often should you replace a teenager's mattress

Most quality mattresses last 7-10 years with proper care. However, if your teenager's mattress is sagging, uncomfortable, or they're experiencing poor sleep, it's time for a replacement regardless of age.

Choosing the right bed frame for teenagers

The mattress is only half the story - the bed frame matters too. Here's what's available:

• Teen beds with storage: Perfect for keeping clutter at bay. These come with built-in drawers or compartments, ideal for storing clothes, books, or gaming gear.
• Teen ottoman beds: Stylish and functional, these lift up to reveal generous under-bed storage. Great for shoes, bedding, or out-of-season clothes.
• Teen loft beds and high sleepers: Brilliant space-savers that lift the bed off the ground, freeing up room underneath for storage, seating, or a study zone.
• Teen bunk beds: Great for shared rooms or sleepovers, these make bedtime fun whilst freeing up valuable floor space.
• Teen beds with desks: Designed for homework and gaming, these beds come with a built-in workspace to support study sessions and hobbies.
• TV and gaming beds for teens: Give them their own space for watching movies and gaming, with a built-in screen that keeps everything neat and tidy.
