Synthetic Versus Organic Latex Mattresses

Mattress Structure

• Traditional mattresses contain an inner framework of metal coils, surrounded by and padded by wool, linen or cotton. To prevent them from sagging or being damaged by excess moisture, they need to be supported by a box spring. Latex mattresses, both synthetic and organic, contain a solid core. At less risk for mold growth, a latex mattress can be laid flat on a platform bed, with no need for support from a box spring.

Creation

• Synthetic mattresses are formed by emulsifying a compound like styrene. The liquid mixture is placed in a mold and aerated and vulcanized. The resulting pad has air bubbles inside of it, which make it pliable while retaining firmness. Organic latex mattresses are formed by obtaining milk from rubber trees. The white liquid is placed in the same kind of mold used for synthetics. It is also aerated and vulcanized. Both synthetic and organic latex mattresses are covered with cotton shells for comfort. Organic latex is covered with organic cotton and is not treated with standard fire retardant sprays.

Use

• The first difference you'll notice while shopping is that the price for organic latex mattresses is higher than for synthetic mattresses. Organic mattresses, including traditional ones, are more expensive across the board. Organic mattresses can be safely used as soon as they are purchased. Synthetic mattresses should be allowed to air out for a few days on a screened porch or in a room with an open window. This allows potentially harmful volatile organic compounds, or VOCs, to off-gas without exposing you to them at night while you sleep. Both types of latex mattresses are resistant to infestation by dust mites and bed bugs.

Considerations

• Both synthetic and organic latex mattresses can last for over 20 years before requiring replacement. Both types of mattresses require similar maintenance to continue to provide you with enough support for a comfortable night's sleep. They should be rotated monthly and flipped at least every six months to distribute wear evenly and extend their lives. As both types of mattresses age, they become harder and more brittle.
