Initially ordered a king size mattress for an existing bed frame inherited from a house sale! upon close inspection the frame wasn't very stable and couldn't be tightened up! so back onto the website which has an excellent choice of beds and mattresses all at competitive prices.It's early days but we are very pleased with our new mattress and bed.Items delivered two days after ordering. All well packaged and delivered on time.Great communication from the courier who phoned and texted me when he was about 30 mins away.

Help & Buying Guides

How deep is a deep mattress?

A ‘deep’ mattress generally refers to any mattress with a depth of over 12 inches (30 cm), with an extra deep mattress usually being over 16 inches (40cm deep mattress). The depth of an average mattress is between 8 - 12 inches. Our mattress depth buying guide will give you more information about these depths.

Why choose a deep mattress?

A deep mattress is perfect for couples or those with heavier builds. Generally, those over 15 stone will find a deeper mattress more comfortable as it can take more pressure before beginning to compress. The deeper a mattress, the more durable it tends to be.

Similarly, pregnant people may prefer a thick mattress as they are known to provide more relief to sore joints and pressure points. That being said, mattress technology is now incredibly advanced, so you can find expert relief in any thickness of the mattress.

What bed frame do you need for a deep mattress?

So long as you check the dimensions of your bed frame and mattress beforehand, you shouldn’t have any trouble fitting a thick mattress on any type of bed frame. The only thing you should consider, however, is how high the deep mattress will come up.

If you have a particularly low bed frame, you might benefit from an extra deep mattress as it will increase the height of the overall bed. However, be sure it doesn’t ruin the look of your bed by coming up too high on your headboard.

Are deep mattresses harder to clean?

Depending on the type of stain or dirt you’re trying to remove, deeper mattresses shouldn't be any harder to clean than a regular depth mattress.

Our guides on how to clean a mattress and how to get blood out of a mattress can give you some helpful tips.
