1. Your mattress gets heavier over time. Why?

During our lifetime we spend about 26 years in bed sleeping, resting, watching TV, etc. No matter what we're doing in bed, we're shedding dead skin cells and losing body fluids (sweat, oil, urine, etc) During this time the mattress is also collecting dust. So your mattress is getting heavier but that's not all...

2. Your mattress might look clean but due to the above, the humid environment inside your mattress is a breeding ground for mould, bacteria and dust mites. Every minute we lose about 30,000 - 40,000 dead skin cells. The more dead skin cells, the more food for dust mites and their droppings can trigger allergic reactions. The more you toss and turn in your bed, the more droppings you release into the air and by breathing them in, you might start sneezing and coughing.

3. Your mattress can cause back and neck pain. 

Everybody has their favourite spot in the bed but with time the mattress might become uneven and fail to support your body.
