🧠 Pro Tips for Matching Bed to Room
Leave at least 24–30 inches (60–76 cm) of clearance on each side for walkways.
Don’t forget nightstands —they need around 18–24 inches (45–60 cm) each.
If space is tight, consider a bed frame with built-in drawers or go vertical with under-bed storage .
Place the bed so it doesn’t block doors, closets, or windows—natural light matters!
