Best Mattresses for Platform Beds in 2025

With a lower-profile design and a wide range of modern and traditional styles, platform beds offer a distinct mattress foundation instead of a traditional box spring. Of course, this also makes finding the right platform bed mattress an important decision, since not all mattresses are created equally — or suitable for a platform bed.

Overall, our pick for the best mattress for platform beds is the award-winning, dynamically supportive Purple RestorePlus® Hybrid Mattress, but plenty of great options could work for your needs.

Read along to learn what to look for when picking a mattress for a platform bed and which ones are our top picks.

What Is a Platform Bed?

A platform bed uses a minimalist, sturdy frame and evenly spaced slats to support the mattress. With a platform bed like the Purple Metal Platform, you don’t need a box spring, which can help you save money when upgrading your bed. Instead, the mattress rests directly on the slats, giving you better airflow beneath the mattress so you can sleep cooler.

What To Look for in a Mattress for a Platform Bed

A platform bed is just one of several types of bed frames you could select for your mattress. Each frame offers different levels of support, style, and functionality, which also influences which mattresses work best for that type of frame. Here’s what you should look for when choosing a mattress to go with a platform bed.

Support and Stability

Platform beds and other box spring alternatives need to provide the right level of support for your mattress, especially if you have a heavier mattress. Generally speaking, a platform bed with metal slats and a solid surface will require less maintenance and offer more support.

When buying a new mattress, double-check the weight limit of your platform bed. Your platform bed should be able to support the combined weight of the mattress and anyone who will be using it.

Suitable Material

When evaluating different types of mattresses, pay close attention to their materials. Memory foam, hybrid, and latex mattresses all work well with platform beds. While some innerspring mattresses can work with a platform bed, larger and heavier ones could sag between the slats. 

Sleep Position Compatibility

You’ll also need to make sure you select a mattress that is compatible with your preferred sleep position. Generally, side sleepers do best with a medium-soft mattress, back sleepers prefer a medium-firm mattress, and stomach sleepers need a firmer mattress. Regardless of sleep position, a mattress that provides targeted, conforming support for your body’s pressure points is best.

Thickness and Height

Platform beds are typically lower than box springs and other bed foundations. However, just like mattresses, platform bed height can vary. Look to combine a mattress and platform bed that will allow you to get in and out of bed easily without straining your joints. 

On average, a good total bed height (including both the mattress and platform) is around 24 inches, but you can adjust based on height, mobility, and other preferences.

Long-Term Durability

When you order a mattress in a box to go with your platform bed, it’s important that you get one that will stand the test of time. Most mattresses last seven to 10 years, but this can vary based on the manufacturing quality and the type of mattress you buy. For example, while hybrid mattresses can last 10 years or more, innerspring mattresses usually only last five to eight years.

Look for mattresses backed by a strong warranty. Purple mattresses are backed by a 10-year limited warranty, so you can have peace of mind about your mattress.

Airflow and Breathability

The slats in platform bed frames help provide better breathability under your mattress. Of course, the type of mattress you buy will also affect its airflow and breathability. These traits are essential for keeping you cool and comfortable throughout the night so you can enjoy high-quality sleep.

Purple mattresses use our proprietary GelFlex Grid®, which dissipates heat so you can sleep up to four times cooler than comparable mattresses.

What Type of Mattress Is Best for a Platform Bed?

There are many types of beds to choose from for a platform bed mattress. But if you’re looking for the best mattress for platform beds, you can’t go wrong with Purple. The pressure relief and cooling offered by the GelFlex Grid® ensure that you’ll have a great night’s sleep in any sleep position.
