California King 11" Medium Hybrid / Pocket Coil Mattress - Mika by SleepKing

The Mika California King is a 72 x 84 medium-firm pocket coil mattress that adds extra length for taller sleepers. Its five-zone coil system, lumbar reinforcement and reinforced edge construction provide the same supportive Mika feel across the larger sleep surface.

Mika by SleepKing is a Canadian-made, medium-firm pocket coil mattress built for supportive everyday comfort without an overly hard feel.

At its core is a five-zone, foam-encased pocket coil system with added support through the lumbar area. Above the coils, layers of visco foam, vertical fibre and medium-soft eco foam add cushioning while keeping the mattress supportive.

A 4-inch reinforced perimeter gives the Mika a firmer, more stable edge—helpful when sitting on the side of the bed and useful for making more of the sleeping surface feel usable.

For someone who wants the contouring of a pocket coil mattress with a supportive medium-firm feel, the Mika lands in a practical middle ground.

What stands out

• Medium-firm feel — supportive without feeling excessively hard.
• Five-zone pocket coils — targeted support across the mattress.
• Extra lumbar support — reinforced through the centre of the sleep surface.
• Layered foam comfort — visco and eco foam provide cushioning above the coil system.
• Reinforced perimeter — a 4-inch edge encasement improves stability along the sides.
• Made in Canada.
