Compact foldable bed with enhanced comfort

A foldable bed comprising:

• a front unit comprising a front frame and a front panel disposed at the front frame;
• a rear unit comprising a rear frame and a rear panel disposed at the rear frame;
• and
• a middle support pivotally connecting the front frame of the front unit and the rear frame of the rear unit, thereby allowing the front unit and the rear unit to fold and unfold relative to each other,
• wherein:
• each of the front and rear panels has a proximal portion;
• when the foldable bed is in an unfolded state, the front and rear panels are substantially leveled with each other and the proximal portions of the front and rear panels are disposed adjacent to each other, thereby allowing the front and rear panels to support a rollable cushion in an unrolled state to enhance comfort;
• and
• when the foldable bed is in a folded state, an upper portion of the middle support, the proximal portion of the front panel and the proximal portion of the rear panel collectively form a groove to accommodate at least a portion of the rollable cushion in a rolled state.
