King Split Head Flex Top Replacement Firm Regular Foam | Firmer-Feel Comfort Layer for Sleep Number FlexTop Beds

A firmer-feel replacement comfort foam cut for King Split Head Flex Top Sleep Number beds, where the head splits into two independent sections so each side can articulate on a FlexFit adjustable base. Same firm foam we offer in standard sizes — configured for the split-head FlexTop King.

Firm feel, 1.8 density, 50 ILD. Made by Carpenter and CertiPUR-US tested. A deep, firm feel with little to no give and no sinking sensation — it firms up your mattress and makes it feel firmer than when new, eliminating body impressions and sagging. This is the firmest of our foam options.
