Best Gel Mattress for 2025, Tested by CNET’s Bed Experts

Introduction: CNET’s Comprehensive Mattress Testing Experience

CNET has become a trusted name in mattress testing, thanks to years of meticulous research and hands-on evaluation. Our team’s journey began eight years ago, and since then, we have tested over 350 mattresses from a wide range of brands, from household names like Serta to niche brands like Sonu. What sets us apart is our diverse team of testers, each with unique body types, sleeping preferences, and needs. This diversity allows us to provide well-rounded insights, ensuring our reviews cater to a broad audience. Our approach isn’t just about quick tests; we often use mattresses for months or even years, offering long-term perspectives on comfort and durability.

Firmness Testing: Understanding the Feel of the Mattress

Firmness is a key factor in choosing a mattress, and we test it meticulously. Using a scale from 1 to 10, we categorize mattresses as soft, medium, or firm. Our team members individually assess each mattress, considering their personal experiences to provide a human touch. But we don’t stop there; our unique Mattress Smasher tool gives an objective firmness score, ensuring accuracy. This dual approach helps us recommend mattresses based on sleep positions and body types, making our reviews both personal and reliable.

Assessing Feel and Comfort: Beyond Firmness

Feel is just as important as firmness. We evaluate how a mattress responds to movement—whether it’s bouncy, flexible, or contouring. Each mattress is described in detail to help you imagine lying on it, as we know you can’t test them all. Whether it’s a plush top or a neutral feel, we cover it all, ensuring you find the perfect match for your comfort.

Temperature Regulation: How the Mattress Handles Heat

Temperature regulation is tricky, as everyone’s body is different. We test mattresses in controlled environments, without bedding, to assess how they manage heat. We recognize that while many brands claim cooling properties, few deliver. Our long-term use helps us provide insights into how a mattress feels over time, considering factors like materials and climate, to give you an honest assessment.

Motion Isolation: Minimizing Disturbances

For light sleepers or those sharing a bed, motion isolation is crucial. We test this by having one person move while another lies still, and by using a water glass test. This helps us determine how well a mattress absorbs movement, ensuring you’re not disturbed by others. Our creative methods ensure you get a clear picture of each mattress’s performance.

Edge Support and Special Features: Ensuring Stability and Innovation

Edge support is vital for those who share a bed, and we test it by sitting and lying on the edges. We also explore special features like cooling covers or zoned support, evaluating their effectiveness. Our goal is to uncover if these innovations truly benefit specific sleepers, providing you with clear, unbiased recommendations. At CNET, we’re committed to helping you make an informed decision, ensuring your mattress is just right.
