Types Of Crib Mattresses

There are three general types of crib mattress: foam, innerspring, and organic. All types – if they are well-built and good quality – will provide excellent support for newborns and toddlers.

  • Foam – Foam crib mattresses are composed of polyurethane. It is the most popular choice for parents and is cheaper than organic or innerspring. Because they are the lightest among the three types, weighing about 5 to 13 pounds, changing the sheets and cleaning baby mess becomes easier.
  • Innerspring – These mattresses are heavier and more expensive than foam mattresses weighing about 15 to 30 pounds. The coils or springs provide a firm level of support, making it one of the most popular options for full-size baby mattresses. If you have decided to get an innerspring mattress, look for one with a gauge of 15.5 or lower and about 135 to 150 coils.
  • Organic – Among the three types, organic mattresses like Newton Wovenair Crib Mattress are usually the most expensive as they are made of 100% organic material. This means it eliminates potentially allergens and harmful chemicals that may be present in some foam mattresses.

What To Consider When Buying A Crib Mattress

What To Consider When Buying A Crib Mattress

When adults are searching for a mattress to buy, we usually look for one that gives support and comfort that we tend to forget about safety. However, safety is one thing that cannot be overlooked when looking for mattresses for children. Determining which one to purchase is perhaps one of the most crucial decisions when it comes to your baby’s health, comfort and safety.

1. Mattress Size

A mattress has to fit perfectly in the crib, with no space between the crib frame and edge of the mattress. Mattresses that are too small may increase the risk of entrapment and suffocation. The size for both cribs and mattresses are standardized by the government. However, not all mattresses will fit snugly in every crib due to slight variations.

The proposed size by the government is 27 5/8” to 28 5/8” of width and 51 ¾” to 53” in length. The minimum size is 27 ¼” x 51 5/8”. Make sure that the bedding is not thicker than six inches.

2. Firmness

The best baby crib mattress is firm, flat and resilient. It may feel very stiff to parents, but babies will easily adjust to it. According to Consumer Reports, when you press on the mattress, it should snap back and not follow the shape of your hand. The bedding should not conform to the shape of your baby’s head and has to be resilient enough to regain its shape fast. If the surface is too soft, it causes your child to sink slightly, making it harder for them to adjust their position.

3. Density

Mattresses with high density provide enough firmness to keep babies safe while sleeping. Most manufacturers do not include density on the packaging, but you can always check the weight to determine the thickness of the item. Compare the weight of different foam models to assess foam density. You can also perform a density test by placing your hand on each side in the middle and press your hands together. It should not allow you to squeeze far.

For innerspring mattresses, it is important to check the gauge of wire. Lower gauge has thicker wire, which means it is firmer and stronger. Opt for a mattress with 135 to 150 coils and a 15.5 or lower gauge.

4. Insulator Pad

The quality of the insulator pad on top of the steel coils in innerspring mattresses is very important as it prevents the coils from poking through. A cheap insulator may feel comfortable but may not hold up in the long run. A good-quality insulator pad contains coir fibers, which are made up of shredded coconut shells. Some mattresses have fiber-wrap pads or rag pads which are made from cloth scraps. Avoid low-quality insulator pads that are composed of woven polyester as these are less durable.

Other Things to Look For

  • Mattress Cover – Look for double or triple-laminated ticking fabrics. These compositions are more resistant to holes, tears, and wet diapers.
  • Venting – Some mattresses like Milliard Crib Mattress and Toddler Bed Mattress have small vent holes on the sides to allow air flow in and out. This will let heat and odors from diapers escape.
  • Border Rods - These are also essential in innerspring mattresses. They provide additional firmness, durability, and support to prevent the mattress from sagging when your baby crawls or stands near the edge.
  • Convertibility – If your baby’s crib is convertible to a toddler bed, consider getting a dual-firmness convertible mattress.
