IKEA spring mattresses are quite elastic. Its open spring structure can promote the air circulation in the mattress, ensure good air permeability, and make people not feel overheated when sleeping. In terms of price, the spring mattress is also the most affordable of the three mattresses. This kind of mattress is most suitable for young people with strong metabolism and fast speed. Ikea has two kinds of spring mattresses: Ponar springs and independent pocket springs. Ponar spring is hourglass-shaped and is the most basic spring type in IKEA, providing basic support and comfort. Independent pocket spring is a patented product of IKEA. Each bagged spring operates independently, and the vibration of some springs will not drive the surrounding springs to vibrate together, thus avoiding the interference of the other side turning over when two people use it, and providing more accurate support and comfort for all parts of the body during sleep. People who are afraid of being disturbed by their partners when sleeping can choose this mattress.
