What to know before buying

Listing details to confirm

The listing conflicts on height adjustment: the title says 4 adjustable heights, while a feature description says 6 settings and gives a range of 27.36 to 32.28 inches. It also varies between 3-in-1 and a title phrased as 3 in 1Baby. Confirm the selected version's height settings and configuration before purchase. The stated dimensions and weight may warrant checking because the listed weight is 16 ounces.

The listing's mesh, convertible modes, and wheels should be assessed as stated product claims, not as customer-verified strengths.
