The Cool Gel 10” King Medium Tight Top Gel Memory Foam Mattress is a trifecta of comfort – three beautifully engineered layers, built in breathability, and enhanced cover design make this an ideal choice. The 10” mattress launched the Cool Gel brand as the original bed and features a tri layer construction consisting of 1.5” inches of Cool Gel memory foam for pressure relieving comfort, a 2.5” supportive poly foam transition layer for enhanced motion transfer and support and 6” of high density supportive base foam. The effect of the three layer model further enhances pressure relieving comfort with the addition of a transition layer so your body weight gently eases into the support of the base layer. All foams are 100% CertiPUR-US certified ensuring they are tested by independent labs for content, emissions, and durability. This mattress features a breathable, waterfall circular knit cover with enhanced top panel and 4 panel border design helping maintain airflow and keep you comfortable as you sleep. This is the King variant, but the 10” Medium Tight Top is available in all standard sizes including Twin, Twin XL, Full, Queen, King, and Cal King. With a 10” profile, this mattress is ideal for primary bedroom use, guest rooms, rental units, Airbnbs, RVs, bunk beds, dorms, and more.
