Budget mattresses sag in two years and wreck your sleep. Casper stays firm for a decade of actual rest.
Why Not Just Buy the Cheap One?
Casper's hybrid construction with coil support and memory foam layers prevents the permanent body impressions that plague budget mattresses like Zinus or Leesa within 24 months. The high-density base foam resists the sagging that turns a $300 mattress into a hammock by year two, leaving your lower back unsupported and your sleep fractured.
The Buy-Once Math
You'll buy three cheap mattresses in the time Casper stays firm—that's $900 to $1,200 in replacements plus the cost of moving them and poor sleep ruining your work performance. Casper costs roughly $1,200 for a decade of consistent support; the cheap route costs triple that plus a decade of waking up achy. One good mattress beats three bad ones every time.
