How To Choose The Right Bunk Bed Mattress For Your Children

According to Cleveland Clinic, children often need around 12 hours of sleep a night, so ensuring their sleep environment is as comfortable and safe as possible is crucial.

When it comes to choosing a bunk bed mattress, there are multiple factors you need to consider.

Thickness

You can’t just throw any old mattress onto a bunk bed. Most standard mattresses are too thick.

There are two types of mattresses commonly used on bunk beds:

  • Low-Profile: Mattresses marketed as low-profile are usually between 2” and 5” thick. They’re most suited to trundle beds, floor beds, futons, and some bunk beds.
  • Thin: Mattresses marketed as thin are usually between 5” and 8” thick. This is what I’d consider the perfect thickness for most bunk beds.

The thickness of a bunk bed mattress is crucial because it needs to fit snugly between the bunk bed rails. If it’s too thick, it won’t fit, and your child could get hurt by falling out of bed.

Most bunk beds recommend a maximum mattress thickness of 8”.

Some may be able to accommodate a thicker mattress (especially if they have extra guard rails, etc.), but it’s always best to err on the side of caution.

Size

Bunk beds come in two standard sizes, twin and full.

You need to ensure you get a mattress that fits the specific size of your bunk bed. A twin mattress won’t fit full-size bunk beds and vice versa.

If you’re unsure what size mattress you need, measure the dimensions of your bunk bed.

Firmness

The firmness of your mattress is important for two reasons:

  1. A softer mattress is more likely to sag and create a gap between the mattress and the guard rails.
  2. Second, a firmer mattress is better for your child’s spine. A soft, sagging mattress can cause back pain and other health problems.

When it comes to mattress firmness for children, you should look for a medium-firm mattress. This will provide the perfect balance of comfort and support.

Materials

Most bunk bed mattresses are made from foam, latex, or innerspring:

  • Foam Bunk Bed Mattress: Memory foam mattresses are among the most popular types of bunk bed mattresses. They’re typically made from polyurethane memory foam.
  • Latex Bunk Bed Mattress: Latex mattresses are more expensive and less common (although growing in popularity with eco-friendly, health-conscious consumers). They’re made from natural or certified organic latex, derived from rubber trees’ sap.
  • Innerspring Bunk Bed Mattress: Innerspring mattresses are usually at the cheaper end of the market. They’re made from a steel coil support system with a layer of padding on top.
  • Hybrid Bunk Bed Mattress: A hybrid mattress is often considered the best of both worlds and will often contain multiple layers of different materials. However, hybrid bunk bed mattresses are not that common because the multiple-layer design makes the mattress too thick to use safely on a bunk bed.

Foam and latex are the best choices for a bunk bed mattress. They’re both comfortable and supportive and won’t sag over time as an innerspring mattress might.

Other materials that you might find in a bunk bed mattress include:

  • Cotton:  Cotton is a natural and breathable material often used for the outer layer of a mattress. However, traditional cotton is a dirty crop and is not considered to be a renewable resource. On the other hand, certified organic cotton is a sustainable fabric perfect for organic mattresses.
  • Wool: Wool is another natural material often used in mattresses for its softness and ability to regulate body temperature. It’s also naturally flame retardant and can eliminate the need to use fiberglass to meet federal fire regulations.

Material Certifications

Greenwashing is rife in the mattress industry.

Many companies out there will try to trick you into thinking that their mattress is eco-friendly and non-toxic with bogus claims and vague buzz words such as ’natural’ and ’green’.

Respected third-party certifications help ensure that the materials used to make your bunk bed mattress are as sustainable and non-toxic as claimed.

Some of the leading material certifications to look out for on your next mattress include:

  • CertiPUR-US
  • Formaldehyde Free
  • Global Organic Latex Standard (GOLS)
  • Global Organic Textile Standard (GOTS)
  • GREENGUARD
  • MADE SAFE
  • OEKO-TEX
  • Responsible Down Standard
  • Responsible Wool Standard
  • USDA Organic

Read more about these and all other environmental certifications to make sure you know what you're buying.

Business Certifications

In addition to material certifications, you should also look for business certifications.

These are awarded to manufacturers and retailers who are run ethically and sustainably. For example, using renewable energy sources or donating profits to charity.

Some of the leading business certifications to look out for on your next mattress include:

  • 1% For The Planet
  • Certified B Corporation (B Corp)
  • Climate Neutral Certified
  • Fairtrade
  • Fair Trade Certified

Price

Sustainable products are often more expensive than mass-produced products that damage the planet. This is because the materials and processes needed to produce healthy and earth-friendly products cost more.

However, if there is one place you should spend a little more to get peace of mind, it’s the mattress your child will potentially spend half their childhood on.

The price you pay will depend on the mattress's size, firmness, and material. For example, you’ll pay more for an organic latex mattress made in the U.S. than a basic innerspring mattress imported from China.

Keep in mind that you get what you pay for. A cheap, poorly-made mattress will only last a few years before it needs replacing.

It’s better to spend a little extra money on a high-quality mattress that will last for years. This will save you money in the long run.

Weight

Bunk bed weight capacities are to be taken seriously, especially when you’re talking about the weight limit of the top bunk.

With this in mind, it’s better to go for a lighter mattress on a bunk bed to ensure you’re under the weight limit (especially when older children use the bunk bed).

If you’re ever in doubt about the weight capacity of your bunk bed, always check the handbook or contact the manufacturer.

Shape/Design

Some bunk beds can come in different designs, so you might need specially shaped mattresses to fit correctly (in an L-shaped bunk bed, for example).

I’ve covered bunk bed shape/design in more detail in my non-toxic bunk bed article.

Noise

Bunk bed mattresses can make all sorts of noise…from the springs creaking to the fabric rustling.

While this might not be a deal breaker for some people, it can be disruptive for light sleepers.

If your children are light sleepers, I recommend avoiding innerspring mattresses.

Use Bunk Beds Safely

Children love sleeping in bunk beds, but they can be dangerous if misused.

According to federal law, bunk beds must meet strict guidelines and adhere to the requirements of the Consumer Product Safety Improvement Act of 2008 (CPSIA).

When using a bunk bed, please follow the U.S. Consumer Product Safety Commission (CPSC) Guidance at all times.

Frequently Asked Questions

Do I Need Special Sheets For A Bunk Bed Mattress?

No, you don’t need special sheets for a bunk bed mattress. However, you might consider using fitted sheets designed to stay in place on a mattress. This will help to keep your child’s bedding in place and looking neat.

I’d also strongly recommend steering clear of polyester. Instead, go for eco-friendly bedding or bamboo sheets.

What Is The Best Way To Clean A Bunk Bed Mattress?

You should vacuum your mattress regularly. You can also spot clean it with a mild eco-friendly laundry detergent (or dish soap) and a damp cloth.

Be sure to let the mattress dry fully before putting the sheets back on it.

Do Kids Need An Organic Mattress?

If your budget can stretch to an organic mattress for your kids, I highly recommend it. Think of it as an investment in their future health and wellbeing.

Children are more susceptible to toxins and chemicals than adults, so it makes sense to choose an organic mattress for them.

What Mattresses Should Babies Avoid?

There are many things you should avoid if you’re looking for an organic mattress for your baby. I’ve covered this in further detail in my best organic crib mattress article.

Is The Kiwi Bunk Bed Mattress Any Good?

The Kiwi Bunk Bed Mattress from My Green Mattress is a decent mattress for bunk bed use. However, I didn’t like the level of support offered by the springs, so it didn’t make the list of recommendations.

The Final Word

When it comes to organic bunk bed mattresses, there are many things to consider before purchasing.

Price, weight capacity, noise, and safety guidelines are all key factors to take into account.

Additionally, you will need to consider the shape/design of your child’s bunk bed to ensure that the mattress fits perfectly.

Finally, for additional peace of mind, look out for green certifications.
