Simmons Kids Daydream 2-Sided Crib and Toddler Mattress - Breathable

In this review of the Simmons Kids DayDream 2-Sided Crib and Toddler Mattress, the bottom line is simple: parents seeking a breathable, low-chemical mattress that can transition from crib to toddler bed will find strong value here. The mattress is GREENGUARD Gold certified and uses CertiPUR-US foam with a plant-based soy core, so the single biggest reason to buy is its focus on safer indoor air and non-toxic construction. It ships compressed in a box and promises easy cleaning with a fully removable, machine washable cover.

Key Features

• GREENGUARD Gold certification: Helps reduce chemical emissions and contributes to healthier indoor air for infants and toddlers.
• CertiPUR-US foam: Foam made without PBDE flame retardants, mercury, lead and other heavy metals provides a safer sleep surface.
• Breathable, machine washable cover: A soft knit cover is fully removable and machine washable, making routine cleaning straightforward.
• Waterproof barrier: Protects the plant-based foam core from moisture and keeps the mattress clean over time.
• Two-sided design: Flip the mattress when your child becomes a toddler to extend usable life and maintain freshness.
• Made in USA: Constructed from imported and domestic parts and backed by a 5-year limited warranty for added peace of mind.

Who It's For

This mattress is a good fit for parents who prioritize low chemical emissions and a breathable sleeping surface for infants and toddlers, especially those who want a product with independent certifications like GREENGUARD Gold and CertiPUR-US. It also suits families who need a mattress that is easy to clean, with a removable machine washable cover and a waterproof barrier for everyday accidents.

Those who want a very plush, pillow-top feel or an innerspring design should look elsewhere; this is a foam mattress with a firmer support profile intended for safe infant sleep. If a fully organic certified label is required, shoppers should check alternative options, since this mattress emphasizes plant-based foam rather than full organic certification.

Pros & Cons

Pros

• GREENGUARD Gold and CertiPUR-US certifications support lower chemical emissions and safer materials.
• Removable, breathable knit cover that is machine washable simplifies cleaning and hygiene.
• Two-sided construction extends mattress life from crib to toddler bed without replacement.

Cons

• Compressed shipping requires up to 48 hours to fully expand, which means you may need to wait before first use.
