Sleepah 5.5 Crib & Toddler Bed Mattress Dual Sided Cooling Memory Foam

Our review of the Sleepah 5.5 crib and toddler bed mattress finds it best for parents who want a safe, breathable and easy-to-clean mattress that fits standard cribs. The single biggest reason to buy is safety: the mattress is CertiPUR certified, 100% lead and phthalate free, and has passed required fire testing without fiberglass, giving new parents confidence while still offering a dual sided comfort option as their child grows. It balances firmness for infants and a softer side for toddlers while adding waterproof, removable convenience for everyday life.

Key Features

• Safety focused construction: Meets and exceeds US crib mattress regulations and contains no lead, phthalates or fiberglass so it feels secure for infant sleep.
• Dual sided comfort: One firm side for babies and a softer flip side for toddlers lets the mattress adapt as a child grows without replacing the whole unit.
• Cooling memory foam: CertiPUR gel memory foam helps airflow and provides a breathable sleep surface that balances contouring with support.
• Waterproof removable cover: The outer cotton cover is fully waterproof and easily removable for machine washing, making cleanup after accidents straightforward.
• Standard fit: Measures 52 in by 28 in by 5.5 in to fit standard cribs and toddler beds snugly and avoid gaps.
• Lifetime support: Backed by a lifetime warranty and US based customer support for peace of mind over years of use.

Who It's For

The Sleepah 5.5 mattress is aimed at parents and caregivers who prioritize safety certifications and a regulated, snug fit in a standard crib or toddler bed. It is a good match for families who want a mattress that can serve an infant and then a toddler by flipping sides, and for those who value a removable, washable waterproof cover.

Parents who need an ultra firm, non-memory foam surface for specific medical advice or who use nonstandard crib sizes should look elsewhere. Also, families wanting an organic-only fabric or a mattress thicker than 5.5 in may prefer different options.

Pros & Cons

• Dual sided design provides both firm infant support and a softer toddler side.

Cons
