Tips for selecting mattresses

one
At first glance, it is important to check whether the mattress has a uniform thickness, a flat surface, and even and beautiful lines, as well as whether the mattress has a certificate of conformity.
two
Use your hands to evenly test the surface of the mattress, distribute the filling evenly, and ensure that the quality of the mattress is good with balanced rebound force. It is best to lie down and feel it for 5 minutes.
three
Tap the mattress and listen to the sound of the spring tapping. If there is a uniform spring sound, it indicates that the spring is good. If there is often a creaking or creaking noise under compression, it is possible that the spring may rust or have poor elasticity.
