Which is better for a kid's bed?

The MLILY is the safer pick for a child's room because it is fiberglass-free and CertiPUR-US certified, and the brand lists kids as a target use. The FDW is cheaper but makes neither claim.

Is the MLILY worth the extra $15?

If certification and a fiberglass-free build matter to you, yes. If you just want a cheap guest or dorm mattress, the FDW at $84.98 does the same basic job.

Neither brand states a warranty or expected life in these listings. The MLILY's 750 lb load rating and two-layer build suggest sturdier construction, but there is no long-term data to confirm it.

Are these mattresses firm or soft?

The MLILY is stated as medium firm. The FDW does not state a firmness level; its gel memory foam Eurotop will feel softer and contour more than a tight-top foam mattress.

Do both ship in a box?

The FDW ships compressed in a box. The MLILY listing says assembly is required, so check how it arrives before ordering.

Which has better buyer feedback?

The FDW's 4.3 comes from 3,843 ratings, which is far more reliable than the MLILY's 4.6 from 10 ratings. Treat the MLILY score as preliminary.

The FDW has far more buyer feedback (4.3 from 3,843 ratings) than the MLILY (4.6 from just 10 ratings), so the MLILY's higher score is thin evidence.
