Types of Crib Mattresses
When it comes to the construction of your crib mattress, there are two types from which to choose:
*Foam mattresses are comprised of foam that is usually made from polyurethane, and they are the most lightweight option. When choosing from this type of mattress, check for firmness by pressing on the mattress, which should spring back readily.
*Innerspring mattresses feature a spring unit in the interior of the mattress that consists of steel coiled springs of varying quantities and thicknesses which tend to make this mattress type more durable. Generally, the thicker the steel and the more springs used, the higher the quality of the mattress. Those beds that possess a border rod of steel that runs along the edges of the mattress also tend to be superior, as the rod keeps the edges of the mattress from sagging with use.
What should you look for in a mattress cover?
The composition of the mattress cover can impact how long the mattress will last. Also known as ticking, the cover should be waterproof or at the very least water resistant. Waterproofing on the surface of the mattress keeps stains and liquids at bay. Choose quilted vinyl or double- or triple-laminated ticking that is reinforced with nylon. Such material is also resistant to tears and holes, and some covers resist bacterial growth on the cover. Organic mattresses generally have cotton covers that are water resistant.
Why do some mattresses have what appear to be vents and others do not?
Manufacturer opinions vary as to whether vents in mattresses are beneficial, which is why you will find both types on the market. Some crib mattresses contain either small eyelet vents or larger round vents on the side of the mattress to increase air flow and keep the mattress fresh. It is thought that the vents allow the mattress to breath, which puts less stress on the seams.
