The quick answer is yes it will. Memory foam compresses far faster than hybrid or latex foam beds.
This is not always a bad thing though, take the example of a new sofa at first when it arrives the cushions may look lovely and plump but when you sit on it you feel like your just resting on the top of the firm cushions, then after a few weeks the cushions ‘bed in’ and you get a more comfortable experience. This is the same with all foams. Our guidance is that all foams will compress at some point, its more important to assess the percentage or amount of compression. The accepted amount of sag is 2cm.
Dip is another matter. A dip is where part of the mattress has compressed beyond its tolerated level, assumed as 2cm in Memory Foam. It is usually the Reflex layer that has failed as there is too much pressure on it for its intended use, or in cheaper mattresses the quality is so low that it will fail when put under stress. This causes a crater or hole effect that’s permanently embedded in the mattress.
This is why it is so important to ensure you choose the right mattress for your specific needs. Choosing the correct mattress for your weight and tension will enable you to reduce the issue of compression or potential sagging that maybe found with an unsuitable bed.
You need to make sure that after this compression you still have enough Memory Foam to react to your body to support it and offer the comfort you require. The prime example would be cheaper Memory Foam mattresses which offer 2cm of Memory foam, leaving little to no room for compression, causing a potential dip.
We only supply 5cm upwards of Memory Foam in multiple layers giving you more confidence that as your bed ‘beds in’ you still have the correct amount of Memory Foam to mould to your body. We wouldn’t recommend any thing less than 5cm of Memory foam or Latex as a top ‘comfort’ layer.
How can I reduce compression and avoid dips? One way is to make sure you rotate your mattress regularly, once a month if possible. This will even out the wear. With a traditional mattress you are guided to turn and rotate the mattress, with Memory Foam some mattresses construction methods make this unnecessary. With our unique dual construction method the topper is fully turnable and can be rotated as well to increase the longevity of your mattress.

Hi,
I’ve had a memory foam bed now for about a year and have started to notice there’s a slump or dip where I lie. I got it I the sale and thought I was getting a good deal. Its a standard memory foam mattress 22cm deep. How can I fix the dip, is there a way to shake it out?
Hi Jenny. Thanks for your comment. Unfortunately if your bed has a permanent dip or sag its impossible to rectify, without replacing the foam. This usually happens with cheaper imported foams. It’s unusual it has happened so soon. I’m guessing from the depth of the mattress that there’s only been a very thin layer of memory foam for the comfort layer. Most foams compress up to 2cm during their lifetime so if you only have say a 2-3cm layer its easily compressed leaving you with no comfort layer at all!
We would always recommend layers of 5cm and above for foams and ensuring that there are multiple layers to ensure progressive comfort. Having a removable topper can help as you can turn and rotate this, where as most memory and hybrid foams construction method means you can’t turn the bed. We do however recommend rotating the mattress once a month to even out wear. Lee
