Our take on the King Koil Intimate Serenity Euro Top Firm Mattress

The King Koil Intimate Serenity Euro Top Firm is a US-made hybrid mattress built for people who want a firm feel with a soft cushion on top. A Euro top of Talalay latex and memory foam sits over a coil support core, and Tencel, silk and New Zealand Joma wool in the cover are meant to keep it breathable. It suits back, side and combination sleepers who want pressure relief without sinking in. Against softer hybrids and all-foam beds, it trades plushness for stability and edge support, though firm-leaning sleepers may find the Euro top softer than expected.

About the King Koil Intimate Serenity Euro Top Firm Mattress

This is a firm hybrid mattress with a cushioned Euro top. The top eases pressure at the shoulders, hips, and back. Beneath it, layers of graphite-infused Talalay latex, HyperGel memory foam, and coils give a stable, responsive feel. It is handmade in the USA.

The cover uses FlexKnit fabric with TENCEL for softness and moisture management. TailorMade hand tufting helps keep the comfort and support consistent.

The ContourFlex Encased Coil System has 825 individually wrapped coils that respond independently. A reinforced foam encasement adds edge-to-edge stability, and Everlast Base Foam provides structural support. The mattress suits back, side, and combination sleepers who want a firmer feel.

Questions and answers

Is the King Koil Intimate Serenity Euro Top Firm good for side sleepers?
King Koil lists it for side, back and combination sleepers. The Euro top cushions the shoulders and hips, but the core is firm, so lighter side sleepers may want a topper.
Does it sleep cool?
The cover uses Tencel, silk and New Zealand Joma wool, and the coil core is designed to promote airflow. That helps compared with all-foam mattresses, though no mattress is actively cooled.
What is a Euro top?
A Euro top is a layer of cushioning sewn into the mattress rather than a separate pillow top. It adds softness over the firm core without the shifting of a loose topper.
How firm is it really?
It is sold as a firm mattress, but the latex and memory foam Euro top softens the surface. Expect a supportive feel with a cushioned top rather than a hard, board-like surface.
What is inside the mattress?
Talalay latex, memory foam and a coil support core, with a cover of Tencel, silk and Joma wool. It is handcrafted in the USA.
Does it need a special foundation?
A firm, flat foundation or adjustable base supports the coil core best. Avoid soft box springs, which can reduce support and shorten the mattress's life.
Where is the King Koil Intimate Serenity Euro Top Firm Mattress cheapest?
At City Mattress, for $2,299.99, as of our latest check.
