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.

Frequently asked questions

Can 3 adults sleep on a king bed?

This depends on two things: each person’s bodyweight and their comfort level. Two average-sized adults will have a lot of space between them on a king. Two adults and a kid/pet will do just fine as well. Things will only start to get cosy when three tall adults come into the picture!

Can two long single mattresses make a king?

Yes! If you put two long single mattresses measured at 92 x 203 centimetres, you can create a king-size mattress.

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.

So happy!

My husband and I have very different work hours and it was impossible to find the time to test mattresses together! Ecosa was a no brainer for us! We have just purchased the king. Very comfortable!

Best sleep ever!!!

My wife and I have bought the king size Ecosa mattress and it is the best decision we have ever made!! It is the most comfortable mattress we have owned and we no longer wake up with aches or pains we had with our 10 year old mattress. Much better value than any mattress you would purchase in a store.
