A Step By Step Guide On How to Choose a Crib Mattress

how to choose a crib mattressThere is a lot of work that goes into selecting a crib for a baby. A parent wants to make sure that the crib will be safe and secure. Once the crib is chosen a parent has the task of finding a crib mattress for the baby to sleep on. There are a number of different mattresses to choose for including organic mattresses and foam mattresses. There are some tips to how to choose a crib mattress that will fit the need of the baby.

When looking for a crib mattress getting one that is the correct size is one of the most important things. There are special mattresses that are designed for the use in a crib. The standards crib mattress has a minimum size of 27.25 inches by 51.25 inches. The mattress has to have a snug fit when placed in the crib. If there is space on either side or gaps that may pose a potential hazard. If the mattress is too small for the crib the baby may get their head or other body part stuck between the mattress and the rail of the crib. If the crib mattress is too large the baby could suffocate due to bowing in the center.

There are a number of mattresses that are designed to fit into cribs. The crib mattress is a costly item and it should be ideal for long term use. The mattress should fit the toddler bed as well. If your crib is not convertible, to save some money, consider buying one of cheap toddler beds.

The thickness of the mattress is another threat to babies. If the mattress is too thick the child can sink into the soft surface. It should not be thicker than 6 inches at the most. Anything thicker than this can be a safety risk. A baby does not need memory foam in order to be comfortable. In fact the firmer the mattress is the better it will be for the baby.

Foam Vs. Innerspring
There are two different types of mattress that can be used in the crib. There are foam mattresses and there are innerspring mattresses. The foam mattress are less expensive but the inner-springs are more durable. When looking for innerspring mattresses find one that has between 135 and 150 coils. The gauge should be lower an 15.5 in order to be good for the baby. The numbers are right on the packaging of the mattresses. They are set forth by the Consumer Reports.

This agency has researched different mattresses and has determined what level of firmness the baby needs. A parent should check out what brands of mattresses this agency recommends before heading to the store. Deciding on what type can want will help you learn how to choose a crib mattress.

The density of the mattress is something else to look at. The best density for a baby is high density. To check the density of the crib mattress perform a simple test in the store. Push a hand down in the middle of the mattress and then remove it. If the mattress is able to regain its shape quickly than it is a good mattress. Babies tend to move around a lot while they are sleeping and if the mattress is not able to quickly regain its shape than it can cause a problem.

Mattress Weight
The weight of the mattress is also important. The average foam crib mattress weights around 8 pounds. Innerspring mattresses tend to be heavier. They weight between 15 and 25 pounds. The mattress will need to be lifted often to change the sheets so weight is something to keep in mind.

Additional Features
There are some extra things to look for in the standard mattress. Many mattresses need to be spot cleaned only. Some of the mattresses may have a protective covering that can be washed in a washer machine. The innards of the mattresses may be hosed down and the mattress will need the proper amount of time to dry. This is something to keep in mind since babies can be messy. They have accidents and cleaning is very important.

Safety is the biggest thing to keep in mind when learning how to choose a crib mattress. Safety is very important to parents when it comes to their baby. The parents want to make sure they are laying the baby down on a mattress that is safe and secure. Like everything else mattresses come with certifications stating that they are safe. When looking for a crib mattress be sure to check for a seal from the Consumer Product Safety Commission. This states that the mattress is safe for the baby. If the mattress does not have this seal move onto another brand.

Mattress Cover
Look for a crib mattress that has a thick cover. The ticker the cover is the better the mattress will be. The best mattresses will have several layers of a laminate coating that has been reinforced using nylon. The mattress will be durable and will be easy to clean up. As the baby grows there will be accidents and this type of mattress will be easier to clean. It will also be less likely to rip or tear.

Organic Crib Mattresses

Many parents are looking for organic options for their babies. Organic is environmentally friendly and does not contain harsh chemicals. There are some things to look for in a quality organic crib mattress. There should be small holes that have been reinforced on both sides of the mattresses. This will allow for air circulations and will help keep the mattress smelling fresh. Be sure to look for an organic mattress that has been certified by GREENGUARD of Oeko Tex to make sure that it is truly chemical free.

Crib Sheets
It is recommended not to use crib sheets on the mattress. The baby should be placed on their back right on the mattress. Many parents do want to put some kind of sheet on the mattress to protect it from wear and stains. If a sheet is going to be used select a fitted crib sheet. This will fit snugly and will stay in place. Avoid putting bumpers , pillows, and toys in the crib. They can pose a safety hazard. Watch the video to learn more on how to choose a crib mattress.

These are some things to help a parent chose the correct crib mattress for their baby. The mattress needs to be firm so it does not pose a threat to the baby. These tips can help a parent make an informed decision when purchasing a crib mattress.

  • Size Of Crib & Mattress: Even though the size of the crib and mattress is regulated by the Federal government, not all crib mattress will fit snugly to every crib. That’s the fact.The minimum dimension of any standard size crib mattress is 27.25 inches X 51.25 inches. Most of the standard size crib DaVinci Kalani 4 in 1 convertible crib or Babyletto Hudson 3 in 1 convertible crib recommends such crib dimension. Besides, if any crib recommends a crib mattress dimension of 52” X 28”, the fitting will be snug. Also, you should understand the fact that the best crib mattress is also the best mattress for toddler too. 
  • Mattress Thickness: Federal regulation allows maximum thickness/height of any crib mattress 6 inches. Anything between 3” to 5” is just perfect.

Most parents make the mistake of getting soft mattress thinking that would ensure comforts for the baby.
