  • The foam tablets are two medium, two soft and one firm for each side.
  • This arrangement allows you to have different comfort levels for each partner on the same bed.

  • The bottom layer is the 2000 odd innerspring coils for the support.

  • All these layers are inside a removable and washable plush fabric. The fabric is hypoallergenic as well.
