Overview
A nursery with a standard crib is the setting for this five inch firm foam mattress. A knitted fleece surface covers two layers of memory foam in a tight top design.
Firm support is the stated aim, with a quiet, odorless build and a cover that carries a hypoallergenic claim in the title. The limit is care, since the cover is hand wash only and no removable cover is described.
Who it's for
Parents refreshing a crib or moving a child to a toddler bed will recognise the firm support and the size. Families with an oddly sized crib, or those after a washable cover, should measure and check first.
Pros and cons
- Two layer foam
- Fits standard cribs and toddler beds
- Quiet and odorless design listed
- Hand wash only
- Weight limit of fifty pounds
- Cover removal not described
- Safety certifications not listed
Performance notes
A firm base layer of dense foam resists sagging under a small child, and the soft surface goes on top for comfort. The stated limit applies to the weight on the mattress. Because the fit depends on the crib frame, measure the crib before ordering.
