5 Little Monkeys Mattress Construction

It boasts an 8” mattress profile suitable for use with most bed frames, including bunk beds and trundle beds.

Mattress Cover – The cover is made with OEKO-TEX® certified organic cotton for a comfortable, soft feel. It is both stain and water-resistant as well as removable for machine washing. 

Comfort Layer – This Dual Phase Change Gel Foam Layer regulates temperature by absorbing heat and channeling it away from the body. It responds slowly to pressure, providing your little one with a comfortable, cushioning sleep surface.

Transition Layer – This layer is made with responsive memory foam to provide some gentle pushback for optimal support, ideal for your child’s sleep posture. The foam features an open-cell design for better breathability, further helping regulate temperature for better sleep.

Base Layer – This dense support layer lends strength and durability to the layers above, increasing the longevity and resilience of the mattress.

5 Little Monkeys Mattress Protector

Made with an organic jersey knit fabric, the 5 Little Monkeys mattress protector is hypoallergenic, waterproof, and machine-washable. It comes with oversized securing bands that help lock the protector in place. 

The Sleep System comes with the mattress protector, but we recommend purchasing a second one in case your little one has an accident. If you have to throw one in the wash, you don’t have to leave the bed unprotected.

5 Little Monkeys Pillow

Finding a good pillow for your toddler can be challenging. The 5 Little Monkeys pillow comes with an adjustable fill, allowing you to increase or decrease the loft for better spinal alignment. The pillow comes in a standard 20 x 26” size intended for use with a standard pillowcase.

Non-Toxic Design

The 5 Little Monkeys sleep system boasts several health and safety certifications, making it an excellent non-toxic option. The mattress foams are CertiPUR-US certified, meaning they are made without CFCs (ozone depleters), PBDEs, TDCPP, or TCEP (“Tris”) flame retardants, without Mercury, lead or heavy metals, formaldehyde or phthalates (air pollutants) – all regulated by the CPSC.

The mattress cover, mattress protector, and pillow are all made with organic cotton. Both the mattress cover and the flame retardant sock are OEKO-TEX® certified. Products with this certification mean you can be “certain that every component of this article, i.e., every thread, button, and other accessories, has been tested for harmful substances and that the article, therefore, is harmless for human health.”

Firmness & Feel

The 5 Little Monkeys mattress has a medium feel. Thanks to the comfort layer, it has a nice plush surface feel, while the transition layer offers good support for optimal spinal health. 

The bed has surprisingly good edge support, which means your toddler is less likely to fall out of bed if they roll towards the edges. Beds with good edge support feel larger than beds with poor edge support; this may be especially helpful if you spend any time sleeping next to your little one.

Another benefit of CertiPUR-US certified foams is low VOC emissions and minimal off-gassing. We did not notice any off-gassing when unboxing the 5 Little Monkeys mattress. That being said, we have read through a few reviews that indicate some customers have experienced a faint foam smell.

If this occurs, leave the mattress to air out. Crack a window if you can, and avoid putting the mattress protector or sheets on until the odor dissipates. 5 Little Monkeys states this can take between 2-24 hours.

Your Life Made Easier

My 4-year-old has absolutely loved her 5 Little Monkeys bed and the cute little stuffed monkey that came with it. At this age, however, accidents are inevitable. But the waterproof mattress protector makes nighttime accidents significantly less painful for cleanup. 

My daughter recently had an accident, but the bed stayed completely dry thanks to the 5 Little Monkeys’ waterproof mattress protector. It’s removable and machine-washable for easy cleaning as well.
