Tivellary Memory Foam Crib Mattress

The dual-sided design is the standout here: one side is described as a solid, flat surface for infants, while the memory foam side is intended to offer a softer feel for toddlers. That gives families a mattress designed to serve more than one stage, rather than a single-feel option they may need to replace as their child grows. A breathable knitted cover and gel memory foam are also intended to help with airflow and heat dissipation. There are, however, two different sets of dimensions in the listing, so fit deserves particular attention.

Technical details

The mattress uses memory foam, with a gel memory foam side for toddler comfort and a firmer side intended for infants. Its knitted outer cover is removable, and the listing says it can go in a washing machine. The cover is described as breathable and hypoallergenic, though no testing or certification details are provided to clarify those claims.

The size figures are not fully consistent: the product name gives 52 x 27.5 x 5 inches, while the description lists 51.7 x 27.3 x 5.25 inches. Match the mattress dimensions to your crib or toddler bed, rather than relying on the word “standard” without that measurement. The listing does not provide a firmness rating or other detailed safety certifications, so those points can’t be assessed from the available information.

Compatibility

The mattress is described as fitting standard cribs and toddler beds. Its two-sided setup is meant to accommodate a change in feel as a child moves from the infant side to the softer toddler side. That flexibility may suit parents who want one mattress for both stages, whereas a single-sided mattress may be a simpler choice if you only need one firmness style.

It makes sense if you want a removable cover and a mattress designed to transition between infant and toddler use. It might not be a great match if you need precisely verified dimensions or want documented safety and firmness specifications before choosing a sleep surface.

Usage tips

Because the foam ships vacuum-compressed, unpack it and leave it flat in a ventilated room so it can recover. The listing says expansion usually takes 24–48 hours, but cold conditions may extend recovery to as long as 14 days. A practical setup is to open the package in the room where the mattress will be used, then allow time for it to regain its shape before making a fit judgment. The cover can be removed for machine washing, which is useful for routine cleanup, no washing instructions beyond that are supplied.

Practical doubts

Does it have two different sides? Yes. The listing describes a firmer, flat side for infants and a softer memory foam side for toddlers.

Can you wash the cover? The knitted cover has a zipper and is removable, the description says it can be machine washed.

How long does the mattress take to expand? It typically takes 24–48 hours, though the listing says recovery can take up to 14 days in cold or low-temperature conditions.

Should you buy it?

This Tivellary mattress is worth considering if you value a removable washable cover and want a two-sided design intended to serve both infant and toddler stages. Its clearest drawback is uncertainty: the listed dimensions differ, and the supplied details don’t include independent safety certifications or measured firmness information. If a confirmed fit and documented specifications are priorities, compare those details carefully before settling on this model, if the dimensions match your bed and the stated two-stage design suits your needs, its format may be a practical alternative to buying separate mattresses for each stage.
