There are many, many different mattress manufacturers out there. Each has its own vision and strategy to sell mattresses. At Custom Mattress Makers, 6 out of our 7 mattress models are "hybrid" (spring and padding) mattresses. We strongly believe this combination yields the best comfort, strongest support and longest life expectancy. When doing an apples-to-apples comparison of hybrid mattresses, our products will well exceed most others in terms of quality. For example, foam density is a great measurement tool when comparing quality. The higher the density of foam, the higher the quality. We are very transparent when it comes to the materials we use in our products and actually list the foam densities (quality level) on each mattress page. Another unit of measurement that can be used is coil count. A mattress with a higher coil count will conform to ones body more effectively than a mattress with a lower coil count. Also, coil gauge is important. Coil gauge is the thickness of the steel wire that makes up the spring. The lower the gauge, the thicker the steel. A thicker steel spring will be more resilient than a thinner steel spring, resulting in improved durability and longevity. If there is a mattress from another retailer you are considering, we strongly encourage finding out the foam density and coil count to do a comparison.
