Zoma Boost 15″ King Mattress — Product Description

What It Is

The Zoma Boost is a 15-inch thick hybrid mattress designed for people who want luxury, enhanced recovery, cooling features, and support. It is built to combine comfort (especially for active / athletic users) with robust structure and airflow. 

Layers & Construction

From top to bottom, here are the main components:

Layer Material / Function
Cover / Top A quilted, cooling cover. Includes advanced cooling fibers / quilted design to help with airflow and reduce heat buildup. 
Memory Foam Layer Graphite-infused memory foam (for heat wicking) just under the cover to contour to the body and relieve pressure. 
Quilted Gel Foam / Transition Foam A foam layer (or layers) after the memory foam to add softness + transitional support that eases the shift toward firmer support beneath. 
Reactiv Foam Layer A responsive foam intended to provide bounce and limit sinkage. Also helps with motion separation so the mattress doesn’t feel too “stuck.” 
Support Core / Coil System Individually wrapped / pocketed coils for support and structure. These coils aid in spinal alignment and add airflow. The edge is reinforced to reduce sagging at the sides. 
Base / Foundation Foam Dense base foam under the coils to provide stability and durability. Ensures the structure underneath the comfort layers is solid. 

Feel, Firmness & Performance

  • Firmness: Rated around 6/10, which is medium-firm. It’s designed to balance cushioning with support. 

  • Sinkage / Contouring: Offers moderate contouring. You’ll sink in a bit (especially in the comfort layers), but the coil core and transition foams prevent you from bottoming out. 

  • Edge Support: Strong edge support thanks to coil construction and reinforced edges. Good for sitting on the edge or sleeping near the edge. 

  • Temperature Regulation: One of its strengths. The graphite in the memory foam, the cooling cover, and airflow from the coil layer all contribute to better heat dissipation. 

  • Motion Isolation: Good, though not perfect. Some motion transfer is detectable—i.e. if your partner shifts, you might feel some movement.
