In the world of sleep, comfort and support go hand-in-hand—and foam mattresses continue to be a top choice for American households. Whether you’re upgrading your bedroom or looking for a reliable option for a guest room or hospital setup, foam mattresses offer a perfect balance of softness, stability, and affordability.

In this 2025 guide, we’ll explore the best foam mattresses available in the US, covering both traditional polyurethane and advanced memory foam mattresses. We’ll also help you choose the best mattress based on your sleep style, body type, and personal preferences.

What Is a Foam Mattress?

A foam mattress is made entirely of synthetic foam materials, designed to contour the body and relieve pressure points. The most common types include:

• Polyurethane foam (PU foam): Lightweight, firm, and budget-friendly
  
• Memory foam: Softer, conforms to your body shape
  
• High-resilience foam: Bouncy and supportive, often used in hybrids
  

Unlike spring mattresses, foam mattresses have no coils, making them quieter and better at isolating motion—perfect for couples and light sleepers.

Benefits of Foam Mattresses

Here’s why foam mattresses remain a best-seller in 2025:

• Pressure Relief: Foam cushions hips, shoulders, and joints
  
• Spinal Alignment: Supports the natural curve of your back
  
• Motion Isolation: Less disturbance when a partner moves
  
• Allergy-Friendly: Resistant to dust mites and mold
  
• Durability: Quality foam mattresses last 7–10 years
