Spacious Sleep Without Compromise

Measuring 150cm wide by 200cm long, a king size mattress gives you more surface area to stretch out, especially helpful if you’re sharing the bed. It’s a great choice for couples, taller sleepers, or anyone who values personal space while resting.

Despite the size, all iSleep king mattresses are delivered rolled and boxed for convenience, making setup stress-free.

Comfort Options That Work for You

Our king size mattresses come in several support styles. Choose memory foam for contouring pressure relief, pocket springs for bounce and airflow, or hybrid models that combine both for balance and support.

Each design is engineered to reduce pressure on key points and promote better spinal alignment, whether you sleep on your back, side, or front.

Built for Long-Term Comfort

These mattresses feature durable foam layers and breathable fabrics that help regulate body temperature through the night. Some models include washable covers with zip closures for easier care. Motion isolation is a strong benefit too, movement on one side of the bed won’t disturb the other.
