The Mika Double Full XL is a 54 x 80 Medium pocket coil mattress with the width of a standard Double and five additional inches of length. It is well suited to sleepers who want extra legroom without moving to a Queen-width mattress.
Mika by SleepKing is a Canadian-made, Medium pocket coil mattress built for supportive everyday comfort without an overly hard feel.
A Medium feel sits in the middle of the firmness range, so the Mika works for back, side and stomach sleepers alike. The visco and eco foam layers cushion shoulders and hips, and the five-zone pocket coils with added lumbar support keep your midsection supported.
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 feel, the Mika lands in a practical middle ground.
