A sub-$100 crib mattress should be chosen by measured fit first, not marketing words. Measure the crib’s manufacturer-specified mattress space and compare it with the exact product dimensions; full-size crib mattresses are commonly around 52 by 28 inches, while mini and portable cribs require a different mattress. Firmness, waterproof surfaces and third-party certifications describe product attributes, not an infant-safety guarantee. Follow the crib and mattress manuals, use only the fitted mattress, and keep the sleep surface clear according to current local safe-sleep guidance.

Buying tips
- Match the mattress’s measured length, width and thickness to the crib manufacturer’s instructions; full-size and mini crib mattresses are not interchangeable.
- Treat dual-stage labels as orientation instructions: use the maker-identified side for the relevant stage and keep the label/manual.
- A waterproof cover does not justify adding loose pads, pillows or extra bedding; follow current safe-sleep guidance and the crib manual.
