What Are Leesa Mattresses Made Of? Materials, Layers, and Key Details

If you’re asking “What Are Leesa Mattresses Made Of”, you’re likely trying to understand what’s inside the mattress, how the layers work, and whether the materials match your comfort and preference needs. This FAQ-style guide walks through the typical components, how they’re arranged, and what that might mean for your sleep experience.

What Are Leesa Mattresses Made Of, In Simple Terms?

Mattresses from this brand are generally made from a combination of foam layers or foam plus coils, arranged in multiple tiers:

  • A comfort layer near the surface
  • One or more transition layers
  • A support core (foam or coils)
  • A fabric cover on the outside

Most models use some mix of polyurethane-based foams, memory-style foams, and pocketed coils, with different densities and firmness levels to create their feel.

What Types of Foams Are Commonly Used?

Memory-Style Foam

Many of this brand’s mattresses include a memory-style foam layer near the top. This material is known for:

  • Slower response when you press into it
  • A contouring feel that can hug the body
  • A generally softer, more pressure-relieving surface

This foam is typically made from polyurethane with added compounds that change its responsiveness and feel.

Polyfoam (Polyurethane Foam)

Polyfoam appears in both the comfort and support layers:

  • Softer polyfoam may be used directly under the cover for cushioning.
  • Firmer, higher-density polyfoam is often used in the base to provide structure and durability.

These foams are usually petroleum-derived, though some formulations may incorporate additives designed to adjust airflow, firmness, or durability.

Do These Mattresses Use Springs or Just Foam?

Many brands in this space offer both:

  • All-foam models:

    • Built entirely from stacked foam layers.
    • Rely on dense foam cores to provide support.

  • Hybrid models:

    • Combine foam comfort layers with a pocketed coil support core.
    • Coils are usually individually wrapped in fabric, helping the mattress flex more independently under different parts of the body.

In hybrids, the basic structure often looks like this:

  1. Top comfort foams (polyfoam and/or memory-style foam)
  2. Transitional foam layer (to smooth the feel between soft top and firm core)
  3. Pocketed coil unit
  4. Base foam under the coils for stability

What Is the Mattress Cover Made From?

The outer cover typically uses a knit or woven fabric, often made from:

  • Polyester or polyester blends
  • Sometimes blended with materials like cotton or performance-style fibers

These covers tend to be:

  • Soft to the touch
  • Moderately stretchy, so you can feel the foam beneath
  • Designed to hold the internal layers in place

Some covers may be quilted with a thin layer of foam or fiber to add extra plushness to the top surface.

Are There Any Special Additives or Features in the Foam?

In many modern foam mattresses, including those from this brand category, manufacturers may incorporate:

  • Air channels or cut patterns in the foam to enhance airflow
  • Infusions (such as gel or other additives) intended to adjust the feel or temperature response of the foam
  • Different foam densities in different layers to balance comfort and support

These features do not change the basic nature of the material—most of the structure is still polyurethane-based foam—but they can influence how the mattress feels and responds.

Why Do the Materials Matter for Sleepers?

Understanding what a mattress is made of can help you anticipate:

  • Feel:

    • Memory-style foams often feel more contouring and slow-responding.
    • Polyfoam can range from soft and cushiony to firm and supportive.

  • Support:

    • Hybrid designs with coils may feel more buoyant and responsive.
    • All-foam designs rely entirely on foam density and thickness for support.

  • Motion response:

    • Foam-heavy designs often limit motion transfer more than traditional open coil systems.

  • Weight and handling:

    • Foam-only mattresses are often lighter than thick hybrids with steel coils.

What Should You Look For in the Materials?

When reviewing what this brand’s mattresses are made of, it can help to pay attention to:

  • Layer breakdown: How many layers, and what type of foam or coils are used?
  • Foam density (if provided): Higher-density foams in support layers are often associated with a more robust feel.
  • Type of construction: All-foam vs. hybrid, depending on how much bounce or contour you prefer.
  • Cover description: Whether it’s knit, quilted, or engineered for a particular feel.

✔️ Quick Mattress Takeaways

Key points consumers should understand about What Are Leesa Mattresses Made Of:

  • Most models use multiple layers of polyurethane-based foams, often including a memory-style foam comfort layer.
  • All-foam designs rely on stacked foam layers, while hybrid versions pair foam with pocketed coil support cores.
  • The support core is typically dense foam or a coil unit, designed to give the mattress structure.
  • The outer cover is usually a soft, stretchy knit fabric, often polyester or a blend.
  • Some foams may include infusions, channels, or cut patterns to influence feel and airflow, but the core material is still foam.
  • Knowing the exact layers and materials helps you match the mattress’s construction to your preferences for contouring, firmness, and responsiveness.

By understanding what these mattresses are made of—from the top comfort foams to the core support layers—you can better gauge how each model might feel, how it’s likely to behave over time, and whether its construction aligns with what you want from a mattress.
