Casper Original Mattress: what owners actually say
Owners report serious quality-control issues with Casper including possible used mattresses shipped as new, rapid softening within months, and warranty disputes, though lighter side sleepers who get a good unit tend to like it.
What owners complain about
- Used mattresses shipped as new SOME
Multiple owners report receiving 'new' mattresses with shipping labels from different years attached, suggesting old stock or used units being resold as new. One commenter confirms this is 'not an isolated incident.'
- Rapid softening and body dips SOME
A 120 lb owner reports the Casper Original got 'extremely soft' within 1 year and was only good for about 4 months, leaving them with 'the worst back, neck and arm pain in my life.' Another owner replaced a 9-year-old Casper that developed dips where they slept. A third owner says their 'soul hurts after having this bed for 3 years.'
- Defective replacements with creases FEW
One owner received a king-size mattress with large creases that never 'inflated,' and the replacement unit had the exact same creases. A third replacement arrived with a grease or oil-like stain.
- Warranty not honored FEW
At least one owner reports Casper does not honor their warranty when the mattress deteriorates after some months of use.
- Mixed comfort between partners FEW
One owner states 'I'm not a fan, but my wife likes it,' and another describes rolling toward their heavier partner because the mattress doesn't support uneven weight distribution evenly.
What owners love
- Excellent for lighter side sleepers
A 140 lb side sleeper calls it 'great' and 'perfect,' noting it doesn't sleep hot and has no complaints. The all-foam Original is described as firmer than the Hybrid, which suits lighter people.
- Zoned support technology
Multiple owners specifically praise the zoned support design, calling it a deciding factor and noting it provides gentle support for shoulders and helps with back issues.
- Does not sleep hot
Owners confirm the mattress does not retain heat, with one attributing it to the Airscape top foam providing a cooler sleep surface.
- Good value at Costco
One owner paid $1100 for a Cal King hybrid at Costco and reports liking it, especially at that price point.
Surprising patterns
- Very lightweight sleepers (120-140 lbs) report the best experiences, while the mattress softened prematurely for a 120 lb owner with a toddler, suggesting body weight alone doesn't predict durability.
- One owner got 9 years of use before dips appeared, while another had severe degradation within 4 months — massive variance in longevity across units.
- Several commenters actively steered others away from Casper after reading about QC problems, indicating reputational damage spreading through word-of-mouth beyond individual bad experiences.
WHO SHOULD SKIP IT
Buyers who prioritize consistent quality control and long-term durability should skip this mattress, as multiple owners report receiving defective or possibly used units and experiencing significant softening or dips within months to a few years, with warranty claims reportedly not honored.
