PCM, or Phase Change Material, in a mattress is an innovative technology designed for temperature regulation, enhancing sleep comfort. These materials change their state (solid, liquid, or vapor) in response to temperature variations. In the context of mattresses, PCMs typically shift from solid to liquid as they absorb heat, creating a cooling effect. This process also works in reverse, where they release heat as they solidify, thus warming up the mattress if it gets too cold. This bidirectional thermoregulation helps maintain an optimal sleeping temperature by redistributing body heat from warmer areas to cooler ones. PCMs are often incorporated into mattress covers or infused into the foam layers, especially in memory foam mattresses, to mitigate heat retention, a common issue with this mattress type. This technology not only enhances sleep quality by maintaining a comfortable temperature but also contributes to the durability and performance of the mattress.

Zoned Lumbar or Tri-Zone Support in mattresses refers to a design where specific zones have varying firmness to support different body areas. The middle zone is firmer for enhanced lumbar support, preventing the heavier midsection from sagging and aiding spinal alignment. Softer zones at the ends cater to the shoulders and feet, providing comfort and relieving pressure. This tailored support ensures proper posture and comfort for various sleeping positions.

ThermaGel Memory Foam is an advanced type of memory foam infused with ThermaGel particles, engineered to provide both comfort and support. This material adapts to the unique body shape of the sleeper, offering superior support for joints and pressure points. The key feature of ThermaGel Memory Foam is its ability to regulate temperature. The infused ThermaGel particles work effectively to disperse heat away from the body, maintaining a cool and comfortable sleeping surface throughout the night. This makes ThermaGel Memory Foam especially beneficial for those who tend to sleep hot or live in warmer climates. The breathable nature of the foam, combined with the cooling properties of ThermaGel, enhances the overall sleep experience by ensuring a balanced temperature. Additionally, the adaptability of the foam contributes to relieving pressure and supporting the body efficiently, thereby extending the life of the mattress.

360-degree edge support in a mattress refers to the reinforcement around the entire perimeter of the bed. This support is vital for several reasons:

1. Preventing Sagging: It helps prevent sagging at the edges, maintaining the mattress's shape and structure over time.

2. Increased Usable Surface Area: With strong edge support, the entire surface of the mattress becomes usable for sleeping and other activities, such as sitting. This is particularly beneficial for couples, as it allows them to use the full mattress without the fear of rolling off.

3. Ease of Mobility: For individuals with mobility issues or those who experience back or joint pain, a firm edge support makes getting in and out of bed easier. It provides a stable base to sit on and assists in transitioning from sitting to standing.

The construction of 360-degree edge support can vary. In some mattresses, this involves using firmer foam or high-density foam wrapped around the core mattress, providing extra support. In others, particularly in hybrid mattresses, the edge support is achieved with coils placed close to the sides.
