If you feel like you are rolling into each other on your mattress, it could be because the mattress is too soft for your combined weight, or the support system has failed, no longer demonstrating good rigidity.
Rolling together is a sign that your mattress isn't good for you, and you should consider upgrading to achieve the best night's sleep.
Most problems with roll-together occur because the mattress's support system isn't firm enough for your body weight. A firmer mattress will solve the problem.
The best technology to stop rolling together is pocket springs – these mattresses have individual springs sewn into pockets. The springs operate independently, so they cannot deform as a single unit to create roll-together (unless broken).
The second best technology is pure foam (no springs), but you must carefully match the firmness rating to your body weight.
Contrarily, open coil mattresses can experience roll-together because the support system operates as a single layer. However, that doesn't mean you will be affected – it simply means you must choose the right mattress.
Roll-together is when a mattress deforms in the middle with people on it, creating an inverse angle that makes you feel like you will roll together.
Roll-together happens when a mattress lacks enough support for the weight on either side - the support system fails, and the mattress dips towards the middle, creating the sensation of roll-together.
Roll-together mainly affects old mattresses and is usually a sign of a broken/degraded support system. For example, springs and foams deform over time, making the mattress dip when you lay on it.
However, there are situations where it can occur in new mattresses.
The most typical reason for roll-together in new mattresses is the firmness rating being too soft. A mattress that is too soft will squish when you lay on it, deforming the areas around your body and making things feel unstable.
Some technologies are also more prone to roll together - open coil mattresses are the most prone to move because the spring bed deforms as a single unit.
Pocket springs and pure foam mattresses are the least likely to experience roll together because the support systems compensate over different zones. Pocket spring mattresses also have the best edge support out of all technologies.
