Next day delivery even when ordered on a sunday. Tracking was very good they gave me drivers name and he rang to tell me when he was delivering. Tracking even gave me a place 20/22 in the deliveries. I highly recommend their delivery service.

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.
