Night tables the same height as your low-profile king bed makes the most comfortable pairing. Low profile king beds are between 18-22” off the ground, and a suitable night table should be about 16-18” tall.
However, you still need to consider if you’ll need a table to hold a few items or extra storage. Low profile nightstands and simple tables are furniture pieces with a lamp, a clock, a few accessories, and a photo frame. Sometimes, nightstands are designed with a single drawer for more effortless organization. Bedside cabinets are small chests of drawers to provide extra storage. The shorter the nightstand, the less storage space it offers.
