The King Mattresses offers generous space for both sleep and play. It's 20 centimetres wider than a queen mattress - giving the best undisturbed sleep for couples. It's hard to go wrong with a size this huge.

Space begets space! Since the king mattress is roomy, it needs a spacious room to house it in. King mattresses require quite a sizeable room of at least 11-12 square metres.

King size mattress

I love this mattress, first time I have woken up and had not had a backache or stiffness , I thought is would be to hard but no it wasn’t. Love love love it.

Best decision ever!

Purchased the Ecosa King Mattress 4 weeks ago and so glad I did. Back and neck pain had me cursing my old mattress which was far more expensive! From day one the Ecosa had felt amazing. So good I ordered the pillows 2 weeks later. Just as good! Adjustable height is a fantastic option.

Great sleep from the very first night

I bought the king size bed and both my wife and I slept well from the very first night on the default medium firmness configuration. Great investment for many good night sleeps and I believe the bed will last for many years.
