Frequently Asked Questions

Sleep Like Royalty On A Super King Mattress

King or queen mattress cramping your style? A super king mattress might be for you.

At 203 cm x 203 cm, a super king (or California king) is the largest mattress – allowing you to stretch out and sleep undisturbed. 20cm wider than a standard king mattress, its luxurious square proportions make it the ultimate statement piece in a well-appointed main bedroom.

Our Super King Mattress In A Box Delivers Ultimate Comfort

Thanks to its outsized dimensions, a super king mattress delivers ultimate comfort for taller and larger sleepers – with zero partner disturbance. Delivered next day in metro areas, an Ecosa super king mattress in a box ensures you’ll enjoy dreamy sleep from the minute you move in.
