- The Purple Mattress
- SoftFlex cover + 2" GelFlex Grid + edge-support foam + 3.5" comfort foam + 4" base foam
- PurplePlus Mattress
- SoftFlex cover + 2" GelFlex Grid + edge-support foam + 2" comfort foam + 3" comfort foam + 4" base foam
Why it matters: Both deliver the same surface Grid and all-foam support concept. PurplePlus puts 1.5 inches more foam between the Grid and the base, so shoulders and hips have more material to compress before they meet the firmer support layer. That is a meaningful upgrade for side sleepers and people who find medium-firm beds too direct. The original avoids charging for cushioning that a back or stomach sleeper may not want.
