Million Dollar Baby Classic Foothill 5-in-1 Convertible Crib

The Foothill model M3901 is generally marketed as a 4-in-1 crib, so the 5-in-1 wording appears to be a catalog error. Its four configurations are crib, toddler bed, daybed, and full-size bed.

The Foothill is listed with four adjustable mattress positions, not five. The support can be lowered as a baby begins to sit, pull up, and stand. [Foothill product specifications](https://www.homesquare.com/Million-Dollar-Baby-Classic-Foothill-4-In-1-Convertible-Crib-In-Mocha-M3901MO.htm)

Yes, but the full-size conversion requires compatible rails such as the M5789 kit, which is sold separately. The conversion uses the crib headboard and footboard with a full-size mattress and box spring.

It uses a standard full-size crib mattress, and one M3901 product specification lists a 50-pound limit for the crib and toddler-bed configurations. The same specification lists 500 pounds for the full-size bed, but the assembly manual and current manufacturer guidance should control for a specific unit.
