The standard size of a bassinet mattress is 16×32 inches. This is the most common size and will fit in most standard-sized bassinets. Measuring the length and width of your bassinet’s corners should help you determine if this 16×32-inch size is suitable for it.

For those with larger than average bassinets, there are 18×36 inch mattresses available as well. These are slightly bigger than the standard option but still fit comfortably in many types of cribs and cradles without taking up too much space or leaving any gaps around the edges where air could escape from underneath the mattress pad or sheets.

This ensures that your little one has plenty of room to move around while sleeping safely on their back throughout the night without having any part sticking out overhanging sides which could potentially be dangerous if they were able roll onto them during sleep times.

For those who require something more substantial than the standard sizes, such as a 20×40 inch mattress for an extra-long crib or cradle, they may find these to be somewhat hard to come by since they are not in as much demand. Though it may take some effort, one should be able to find the desired mattress size with a bit of searching and luck.

Always double check measurements prior to making a final decision regarding which type and size best suits your needs; otherwise there is potential risk of returning the product due to incompatibility issues further down the line. Better safe than sorry.

It’s important to keep the mattress clean and free from allergens, dust mites, bacteria, and other irritants that can cause health issues. Here are some tips on how to properly care for your bassinet mattress:


Cleaning a bassinet mattress should be done regularly using gentle cleaning solutions such as baking soda or white vinegar mixed with water. Avoid harsh chemicals when cleaning as these can damage the fabric of the mattress or leave behind residues that could be harmful to babies. Utilize an aged toothbrush or soft material to scour away any dirt and grime before giving it a good rinse with tepid water. Allow it to air dry completely before putting back in the bassinet frame.


Store the mattress flat in a cool, dry place away from direct sunlight and moisture when not in use. This will help prevent mold growth which can be hazardous if inhaled by babies while sleeping on their mattresses. Additionally, make sure you cover it securely with plastic wrap so it stays protected from dust mites and other contaminants that could accumulate over time if left exposed in storage areas like closets or attics.

Give the bassinet mattress a thorough inspection prior to placing it into its frame each time you use it. Scan both sides of the fabric for signs of wear-and-tear, such as tears, rips, stains and loose threads that may have come undone during washing or storage processes – this is especially crucial since they could pose potential choking hazards if ingested by babies while playing around them. If any visible defects are detected on either side, swap out immediately instead of gambling with further damage down line due to possible deterioration caused by continued usage over time (even though minor).
