5 Little Monkeys’ Mattress for Kids

At 5 Little Monkeys, we believe that healthy, sound sleep is critical for kids. Unfortunately, most kids mattresses on the market leave a lot to be desired. That's why we’ve created the 5 Little Monkeys Sleep System: a revolutionary children’s mattress that uses specialized technology and organic material to create a bed designed for kids from the ground up.

Common Questions About Our Kids Mattress & Products

The 5 Little Monkeys team wants all of our customers to understand the in’s and out’s of our children’s mattress. For this reason, we like to be transparent and upfront about all the details of our products so that you can make the best choice for your child’s sleep system. Please find the most frequently asked questions about our toddler mattress below. And, if you don’t find the answer to your question, please contact our kids mattress team directly.


We recommend using the 5 Little Monkeys Platform Foundation to support the mattress. However, our kids mattress is compatible with most solid surface or slatted platform beds, bunk beds, foundations, box springs, daybeds, and trundles. Our mattress can also be placed on the floor during the transition from crib to big kid bed.

It may be a mattress designed for kids, but there's no weight limit on our kids' sleep system bed – and we encourage parents to snuggle in bed with their little ones!

The 5 Little Monkeys Mattress is made from a unique blend of 3 types of foam: the Comfort Layer has temperature-regulating memory foam technology, the Support Layer is made with responsive memory foam to help support lighter-weight bodies, and the Base Layer strengthens the layers above for durability, comfort, and resilience.

Well, we wanted to surprise you, but... Yes, it is! We hope you enjoy the monkey with each sleep system bed purchase.

  • ● Kids have lighter weight bodies, so we designed our support layer to have responsive foam for proper support.
  • ● Kids make "mistakes" so we made sure the fabric used on our cover is stain and water resistant, plus the cover is removable and machine washable with a heavy duty zipper for easy clean up.
  • ● We only use safe materials including organic cotton in our textiles that are OEKO-TEX ® certified and CertiPUR-US (r) certified foam.
