When it comes to finding your perfect mattress, you may start to feel like a sleep-deprived Goldilocks. You don’t want a mattress that’s too thin, which can strain your back and break down faster, but you aren’t sure how thick you want your mattress to be
With over one third of our lives spent in bed, the quality of your mattress, including its thickness, can play a key role in your overall health and happiness.1
That’s why we’re here to help.
In this mattress thickness guide, we’ll break down the various levels of mattress thicknesses to help you determine the best choice for you based on your unique sleep needs, including your sleeping position and body weight. That way, once you’ve identified the signs you need a new mattress, you’re guaranteed to find a mattress that’s just right.

Mattresses are comprised of layers that, when combined, can range from between 2 inches thick to over twenty inches thick.2
These layers are divided into two categories:
Like the foundation of your home, the base layer of your mattress is responsible for providing overall durability and support. Without a thick enough mattress foundation, a bed will show signs of wear and tear sooner, such as sagging in the areas where your hips and low back lie. For optimal performance, your mattress foundation layer should be around 5 to 6 inches thick.2
The remaining layers of your mattress are comfort layers. These layers contribute to healthy spine alignment, pressure relief, and motion isolation (meaning the reduction of movement when your partner won’t stop tossing and turning in the night). When these factors come together, they form a comfort trifecta—a team of sleep superheroes working to save you from nights of discomfort and restlessness.
However, if your comfort layers are too thin, you won’t receive the proper support you need to keep your spine in alignment and alleviate pressure from your lower back, shoulders, and hips no matter your go-to sleeping position. This occurrence may even prompt you to research how to fix a sagging mattress if indentations begin to form within the thin comfort layers of your bed.
Similarly, if your comfort layers are too thick, you can experience that oversized marshmallow sensation, which also isn’t ideal for the health and longevity of your spine (or your bed).
When it comes to thickness, mattresses can be separated into five distinct categories.
In fact, the Casper Original Mattress falls into this category. It boasts eleven inches of polyurethane foam designed to ergonomically align your spine while also allowing air to circulate and keep you cool throughout the night when you’re tucked in between your bed sheets.
The Casper Wave Hybrid Mattress is a perfect example of a thick profile mattress. Its 13 inches of support consists of 3 layers of AirScape cooling foam, supportive gel pods, and resilient springs for additional lift and bounce.
While understanding the categories of mattress thickness can narrow down your mattress search, identifying your unique sleep preferences and needs can help pinpoint the exact mattress of your dreams.
When choosing a mattress thickness, you’ll want to consider:
Similarly, if you have a tall bed frame, you probably want to forgo an extra thick mattress and avoid leaping into and out of your bed every day.
No matter whether you’re in the market for a softer mattress or a more firm mattress, with a Casper mattress, you can cozy up to pressure point relief, ideal spinal alignment, and long-lasting durability to achieve the sleep you’ve been dreaming of.
