Smooth Fibres From Wood Cellulose
TENCEL™ fibres are botanic in origin: they're made from cellulose, the natural material that gives trees and plants their structure, sourced from wood. Under a microscope, each fibre has a smooth, regular surface, so it creates less friction against your skin than rougher fibres do. Cellulose also attracts water, so the fibres absorb moisture and release it into the air instead of trapping it against your skin, as many synthetic fabrics can.
Gentle on Skin, Drier Through the Night
A smooth, soft surface feels gentle against your skin from the moment you lie down. And because the fibres draw moisture away rather than holding it against you, you stay drier and more comfortable through the night, with less to disturb your sleep.
Spreads Weight Over a Larger Area
Pressure is your body weight divided by the area supporting it. On a firm surface, that weight concentrates at your shoulders and hips. Memory foam is viscoelastic: it softens in response to body heat and pressure, slowly moulding to your shape and spreading your weight across a larger area. Infusing it with NanoGel helps keep this layer cool, since memory foam on its own tends to hold heat.
Cool Pressure-Relief
Less pressure at your shoulders and hips means less of the aching and numbness that make you toss and turn. With your spine resting in its natural curve, your back and neck can fully relax, helping you wake up feeling more rested.
A Gradual Soft-to-Firm Transition
A transition layer sits between the soft comfort foam and the firm support beneath it. Without one, you can sink through the soft layer and feel the firmer base below. A dense middle layer slows that sink and spreads your weight gradually, so support builds smoothly from soft to firm. ISO 20743 is the international lab test used to measure how well a material inhibits the growth of bacteria.
Comfortably Supported, Spine Aligned
Support that builds gradually means no sinking-through feeling, so your hips and shoulders stay comfortably supported and your spine stays aligned. Antimicrobial foam inside the mattress also helps keep it fresher for longer.
High-Density Foam Resists Sagging
The base layer carries most of your weight and determines how well a mattress holds its shape over time. Foam density, the weight of foam in each cubic foot, tells you how much material is doing that work: higher-density foam resists sagging and body impressions for longer. Resilience describes how quickly foam springs back after it's compressed, which is what lets TerraBase flex with an adjustable base and return to flat without losing its support.
Supportive Year After Year
A firm, stable foundation keeps the whole mattress supportive, so it holds its supportive feel year after year. It moves smoothly with your adjustable base, and CertiPUR-US certified foam means better air in your bedroom and peace of mind.
