There are broadly five types of mattresses available in India
Strictly avoid Memory foam mattresses
Memory foam mattresses are best for back pain and body aches. But they can be potentially dangerous and harmful. They can be inflammable, not child safe and releases toxic emissions. Read more at Wikipedia. To ensure the mattress safety, buy only CertiPUR-US certified mattress. Based on our research, unfortunately,CertiPUR-US®certified mattresses are not available in India.
Better to avoid Latex mattresses
Latex mattresses are most expensive of all the mattresses. The advantage you get is long term durability. Latex mattresses can easily withstand up to 10 years. But we have not found certifications on Latex safety. If you are keen on this ask the vendor for product manual and look for certifications. As it is super expensive you can safely ignore it.
Coir mattresses are firm
As the name suggest coir mattress is made of Coconut coir and very much eco-friendly, healthy as well. But coir is by nature hard so Coir mattresses are not superior in terms of softness and comfort.
Spring vs Foam mattresses
Spring mattress is made of springs and small coils stuffed under and have a nice cushion wrapper. The foam mattress is filled by foam with multiple layers. Spring mattresses are cheaper than Foam mattresses. The main difference is bounce nature of Spring mattresses, called as motion transfer. If your partner moves in sleep it may effect you. If you can easily wake up in sleep because of movements then Spring mattresses is not good choice. If you sleep alone, or your partner sleeps like a rock, or you don’t care even if your partner moves then Spring mattresses suits you.
