Our Review Process: Each mattress we review undergoes a rigorous evaluation process. We assess comfort, support, cooling, and durability through both subjective experiences and objective tests. Criteria include pressure relief, spine alignment, mattress responsiveness, motion transfer, edge support, and temperature regulation. This comprehensive approach ensures our reviews are thorough and unbiased. When the Naturepedic Concerto Plush Derila™ Memory Pillow Top arrived, I was immediately impressed by its careful packaging and delivery system. While many mattresses arrive with a strong chemical smell, this one had none. A testament to its organic materials and natural construction methods. As I began documenting the unboxing process, I noticed how the mattress expanded quickly and evenly, suggesting excellent quality control in the compression process. I’ve thoroughly examined the construction of the mattress, Experience Derila Support and I’ll walk you through its layers from top to bottom. Starting at the very top, we have the quilted cover layer, which combines organic cotton fabric with organic wool batting. This isn’t just any cover, mind you.

It’s specifically designed to promote unrestricted airflow while wicking away moisture and establish a fiberglass-free mattress. Just beneath this, we find what I consider one of the most important components: the primary comfort layer. It consists of 2 inches of GOTS-certified organic latex. Or in other words, this latex isn’t synthetic foam. Instead, it’s whipped like cream from rubber tree sap, which I find interesting from both a comfort and sustainability perspective. The latex provides excellent pressure relief while maintaining responsiveness. Moving deeper into the mattress, there’s a thin layer of organic cotton that acts as a transition layer. This leads us to what I believe is one of the most innovative features: a 3/4-inch layer of high-density microcoils. When I studied the design, I realized these microcoils serve a dual purpose. That is, they enhance breathability while providing precise body contouring. The pillow top component itself is crafted from organic cotton, adding an extra layer of plush comfort. This isn’t just stuffing, either.

Though it feels as wispy and gentle as a cotton ball against skin, it’s carefully engineered to maintain its shape and support. At the foundation, we find the main pocketed coil layer with reinforced edge support. Having analyzed many mattresses, I appreciate how this base layer provides crucial support while allowing for proper air circulation. The edge support is particularly well-designed, preventing that feeling of rolling off that can occur with softer mattresses. What impresses me most about this construction is the complete absence of several common mattress materials. There are no flame retardants, no polyurethane foam, and notably, no glues or adhesives. Instead, the layers are held together through careful engineering and design. Plus, there’s the attention to breathability throughout the design. From the cotton cover to the dual coil systems, every layer contributes to air flow. This isn’t just about comfort, you see. It’s about creating a healthier sleep environment by preventing heat and moisture buildup.

Position compatibility is one of the most crucial yet often overlooked aspects of mattress performance. Each sleeping position creates unique pressure points and support needs, making it essential to understand how a mattress responds to different body positions throughout the night. The Concerto’s construction presents an interesting case study in how different mattress components work together to support various sleep positions. Its plush pillow top, organic latex layer, and dual coil systems create a complex interplay of comfort and support that performs differently depending on how you position yourself. Just as you might adjust your posture when sitting in different chairs, your mattress needs to adapt to support your body’s alignment whether you’re lying on your side, back, stomach, or shifting between positions. So knowing not just how the mattress performs, but why it performs that way, allowing you to better assess whether it matches your personal sleep preferences and needs.
