King Koil Intimate Serenity Tight Top Firm Mattress

Description

Luxurious, firm comfort with responsive support and cooling.

If you like a firmer mattress with a smooth, supportive sleep surface, the King Koil Intimate Serenity Tight Top Firm is a great choice. Unlike a Euro top, its streamlined design puts you closer to the supportive layers beneath, creating a firmer, more responsive feel that makes it easy to move and change positions throughout the night.

Responsive Talalay latex and micro coils provide comfortable pressure relief, while breathable Tencel, natural silk, wool, and airflow-promoting coils help keep you comfortably cool. Handcrafted in the USA with King Koil’s premium materials and attention to detail, it delivers the elevated comfort and craftsmanship the Intimate Collection is known for.
