Specs: Hybrid vs Foam Build
Thickness and Profile
Grbsy offers a 16-inch profile for the hybrid model and a 12-inch profile for the memory foam version. The thicker hybrid design includes a Euro-top and additional comfort layers for deeper cushioning. The 12-inch foam mattress provides substantial height for an RV setting without bottoming out. Both options expand after unboxing. You choose the height that matches your frame height and comfort preference. The 16-inch option adds four inches of material for pressure relief, while the 12-inch model focuses on responsive support in a more compact profile.
Firmness Level
The 16-inch hybrid mattress is rated as medium firm. This balance aims to contour to your body while keeping your spine aligned. The 12-inch memory foam mattress is rated as firm. This higher firmness level provides a solid, responsive surface that resists sinking. The firm rating helps lift the spine in tight RV quarters. You select medium firm for a plush feel or firm for a solid, supportive base. The difference affects how much you sink into the bed and how stable the surface feels when you move.
Mattress Construction
The hybrid model combines pocketed springs with cooling gel memory foam and a breathable Euro-top. This construction uses over 1000 individual coils for support and airflow. The memory foam model uses high-resilience foam layers and HEXACELL dynamic-response foam. This all-foam build absorbs vibration and adapts to your curves.

Cover Material

The memory foam mattress uses a cool-touch IceSilk cover that is washable. The washable feature is practical for RV maintenance.
