Mattresses made of natural materials, such as memory foam and pure latex mattress, are green and environmentally friendly, but their cost is high, formaldehyde pollution, and the damage to the human body can not be ignored. Therefore, high-quality mattresses do not smell pungent.

Look at the quality of a mattress, the most intuitive is to see its material. The high-quality cloth feels comfortable and smooth, without obvious wrinkles and jumpers.

If the interior of the mattress is zipper design, you might as well open it and look at its internal technology, whether the spring is rusty, and whether the interior of the mattress is clean and tidy.

So is the harder the mattress, the better? This is definitely not true. A good mattress should have moderate softness and hardness. Because only the mattress with moderate hardness and softness can support every part of the body perfectly, which is beneficial to the health of the spine.
