What type of king size mattress should I choose?

King size mattresses are available in different constructions, including pocket sprung, memory foam and hybrid mattresses. The best option depends on your preferred firmness, support and sleeping feel, so consider mattress construction as well as size when comparing models.

Should couples choose a double or king size mattress?

A double mattress can comfortably accommodate two people, but a king provides additional width and length. Couples who have sufficient bedroom space and prefer more individual sleeping room may therefore find a king size mattress more comfortable.

Are king size mattresses available in different firmness levels?

King size mattresses are available in a variety of comfort and firmness options. Your preferred firmness should be based on factors such as sleeping position, body weight, mattress construction and personal comfort rather than the size of the mattress.

From order to delivery, everything was seamless. I received clear updates throughout, and the delivery team assembled the furniture and took all packaging away. I've trusted Fishpools for over 50 years - always reliable. One very happy customer!

It’s rare these days, but Fishpools always does exactly what they promise - on time, every time. The quality is excellent, and spending a little more is worth it for the peace of mind you get in return.

Our 2-hour delivery slot was confirmed by 4 pm the day before, followed by a call when the truck was just 30 minutes away. The fitters were friendly, professional, and efficient - even laying down a runner to protect our hall floor. They made sure I was happy before signing and even thanked me for the tea! Highly recommend Fishpools.
