Frequently Asked Questions (FAQs)

1. Is memory foam mattress good for toddlers?

American Family Physician reports that memory foam can increase the risk of re-breathing or suffocation for babies. David and Lindsay Jones encourage other parents to be extra vigilant, or even consider buying a different type of mattress, if you have babies or toddlers.

2. What mattress is best for a toddler?

The best mattress for a 3 year old is a memory foam mattress. Their hypoallergenic properties mean insects and dust are not attracted to them and the foam is no fun to jump on, meaning they will not break down the mattress by jumping on it!

3. What kind of mattress should a 2 year old sleep on?

Crib Mattress Both are very firm, which is important as it prevents infants from sinking into them. Many parents choose to simply use their crib mattress on a toddler bed until their child is 2 to 3 years old and ready to move into a larger bed, as toddlers still find this firmness to be comfortable.

4. What size mattress do you need for a toddler bed?

The standard toddler mattress size is the same as a crib mattress: 27 ¼ inches x 51 ⅝ inches. Many cribs—often called convertible cribs—turn into toddler beds using the same mattress. Some even convert into a twin bed or daybed as well. Toddler bed dimensions can vary if you're using a non-standard crib.
