How do I choose the correct bed base size?

The bed base must match the mattress size exactly to ensure proper, stable support.
If you already have a bed frame, carefully measure the internal dimensions to make sure the base fits perfectly. Also check the height of the bed base profile:

• If it’s too high, the mattress may protrude beyond the edge of the frame.

• If it’s too low, it may sit too deep inside the frame, making it uncomfortable to sit down or get up.
