Feel
Sleep Number c2: adjustable air with foam comfort top. Feel changes based on your number setting. Purple: grid that flexes under pressure points and stays firm under your back. Distinctly different from both foam and innerspring.
Cooling
Purple wins decisively. The open grid breathes; Sleep Number is comparable to standard mattresses (the foam top traps some heat).
Couples compatibility
Sleep Number wins. Dual-zone firmness lets partners with different preferences both sleep happy. Purple is single-firmness across the bed.
Durability
Sleep Number: 15-20 years for the air chambers and pumps (some component replacement around year 10-15). Purple: 7-10 years before grid compression becomes noticeable.
Who should buy which
Sleep Number if: You and your partner have different firmness preferences, you want long-term adjustability, you do not mind air bed feel.
Purple if: You sleep hot, you want responsive (less stuck) feel, you prefer a more traditional mattress experience without app-based adjustment.
