Unlike a traditional innerspring mattress, the Helix Kids Mattress is a hybrid mattress designed primarily with foam layers. It will require a solid support system to prevent any dipping or sagging in the surface of the mattress.
In order to comply with the terms of our warranty, you will need either a solid platform bed or a slatted foundation with thick, wide slats and no more than 5 inches between each slat. We do not recommend using a traditional box spring with your Helix Kids Mattress.
