A foldable frame includes: inverted U-shaped rods aligned in a folding direction, each inverted U-sahped rod having opposite first and second upright portions; and first and second connecting units. Each of the first connecting units interconnects the first upright portions of two adjacent ones of the inverted U-shaped rods. Each of the second connecting units interconnects the second upright portions of two adjacent ones of the inverted U-shaped rods. Each of the first and second connecting units includes two connecting rods that intersect and that are pivoted to each other, and that are respectively pivotable with respect to the respective ones of the first and second upright portions of two adjacent ones of the inverted U-shaped rods, and two sleeves respectively and slidably sleeved on the respective ones of the first and second upright portions of the two adjacent ones of the inverted U-shaped rods, and respectively pivoted to the connecting rods.
