Baby Crib Mattress Buyer’s Guide

When shopping for a crib mattress, there are several factors you should carefully consider—factors we have discussed in further detail below.


All modern-day baby cribs and mattresses are required by law to adhere to certain size dimensions. According to the Consumer Products Safety Commission—a federally-run organization—all baby cribs in the United States must have the following dimensions: 28 ± 5⁄8 inches wide x 52 3⁄8 ± 5⁄8 inches long.

With these dimensions in mind, it is imperative that you select a crib mattress that also adheres to these size guidelines. These guidelines were instituted to prevent babies from falling between the mattress and the side of the crib—events that can injure babies and have even proven fatal in certain instances. As a rule of thumb, there should be no more than 1.25 inches between the crib mattress and all four of the inner sides of the crib. If you do not have a tape measure or ruler handy, you can always measure this distance using your fingers—you should be able to fit no more than 2 fingers between the sides of the mattress and the crib railings.

Types of Crib Mattresses

There are several different types of crib mattresses from which to choose, all of which have advantages and disadvantages. In fact, the type of crib mattress you decide to purchase is actually more a matter of preference than it is quality, so let’s take a look at the three primary categories when it comes to crib type: foam crib mattresses, inner spring crib mattresses and organic crib mattresses.

Foam Crib Mattresses

One of the newer types of mattresses to hit the market is the “foam crib mattress.” These mattresses are made with a type of soft polyurethane stuffing—a substance used in shoe insoles, floor matting and other products where cushioning and support is an absolute must. Along with their layers of polyurethane, foam crib mattresses—which are the lightest type of mattress on the market—contain other supportive materials to ensure the ultimate in comfort and stability. Most foam mattresses are also adjustable and they handle liquid spills very well.

Innerspring Crib Mattresses

Innerspring crib mattresses have been around for decades and are still the most popular type of mattress on the market today. Firm and reliable, these mattresses rely on patterned coils to provide support and comfort to your baby as they sleep. No mattress type on our list is firmer than the innerspring crib mattress, making them very appealing to parents with young infants, but they do tend to be heavier and more expensive than foam crib mattresses.

Organic Baby Mattresses

The absolute latest (and most expensive) type of crib mattress to hit the market is the organic crib mattress. These mattresses are made with a variety of purely-organic materials and processes and are completely allergen free—a great selling point for those worried about pollutants and the preservation of the planet. Once produced, the organic crib mattress provides a great degree of softness, durability and longevity.


Firmness is and should be a major concern when picking out a baby’s crib mattress. For newborns and infants especially, you should definitely consider purchasing a crib mattress that is very firm without sacrificing comfort. Many people mistakenly assume that softer is always better when it comes to a crib mattress, but that is simply not true. Babies will adjust to their crib mattress regardless of the firmness, and because mattresses that eventually sag can be uncomfortable and even dangerous in certain situations, we recommend you choose the firmest crib mattress within your budget.


Crib mattresses may need to be removed from time to time for cleaning or when changing sheets, so be sure to choose a mattress that you can get in and out of the crib without too much strenuous effort. Fortunately, there is a wide range of crib mattress weights, with some weighing as little as 7 pounds up to the innerspring mattresses that typically weigh about 25 pounds.


Density is also important in a crib mattress, but because most manufacturers do not include “density” in the product description, you can always do the following: Check the weight of the crib mattress; heavier crib mattresses tend to be firmer and denser. Also, take a look at the number of coils. According to experts, “a quality baby mattress should have more than 135 coils, along with a gauge of 15.5 or lower.”


By following some of the guidelines we have listed above, along with giving some consideration to how easy or difficult a given mattress will be to clean, you should have no problem selecting a crib mattress that suits your needs—a mattress that is both safe and comfortable, ensuring a good night’s sleep for your baby—and for you.
