King Mattresses

A king size mattress is 150cm wide and 200cm long, this is equal to 5 feet wide and 6 feet 6 inches long. A standard ‘King Size’ (5’0”) mattress includes a longer length than the standard ‘double’ mattress at 6’6” instead of 6’3”.  A king size mattress will provide plenty of room for two adult sleepers, but is ideal for larger bedrooms with more space available.

OUR EXPERT MATTRESS BUYING GUIDES

Let customers speak for us

excellent mattress; excellent customer service

I rarely write glowing reviews but this is definitely deserved on this occasion. MASA Sleep offered fantastic customer service beginning a long chat with an advisor before I decided whether and what mattress to buy and I was even offered a customized option. At no point did I feel under any pressure to make a purchase or to be talked into a more expensive option. The company who delivered the mattress sent regular updates and the mattress itself is extremely comfortable and appears to be of a much better quality than a much more expensive mattress I purchased in the past. i am definitely going to recommend to friends and family. 10/10 I cannot fault the mattress or the service and wish MASA Sleep every success in the future.

I love it ,Very good mattress doesn’t retain heat keeps you cool on a night. It is a big thick mattress made of high quality feeling firm enough to support your back but also soft enough to relieve pressure perfect combination for me. Very good value for money.
I highly recommend.

Great UK made mattress

I try and buy UK made where possible and came across the Aura Refresh 4500 mattress from MASA Sleep. I was drawn to this mattress as they are made upon order haven't sat there rolled for months unlike mattress in a box which I have not had a good experience within the past. This mattress is so comfortable and supportive i wouldn't be without it and the craftsmanship brilliant. Great value

Aura Refresh 4500 Medium Soft Mattress
Mattress is very comfortable

We bought our new mattress on a special offer and were delighted by the prompt and efficient service. This mattress is everything it claims to be - medium soft and well sprung and filled. Does keep us cooler in the night and so far we absolutely love it. Would highly recommend Masa sleep.
