By The Mattress Review Editorial Team · Published October 27, 2026 · Facts last checked September 20, 2026
The casper one mattress lists from $599 to $899 for queen during mid-2026 sales. This 11-inch all-foam model uses breathable polyurethane layers with a medium-firm feel and ships compressed to all 50 states.
It suits side and back sleepers who want CertiPUR-US foams, free shipping and a straightforward 100-night trial after the first 30 nights. The 10-year limited warranty covers indentations over one inch.
Shoppers seeking hybrids, advanced cooling or maximum edge support should consider other Casper lines such as Dream or Snow instead.

How does the casper one foam mattress handle temperature?
The casper one foam mattress uses open-cell construction that manufacturer materials describe as breathable. Owner feedback aggregated on review sites shows mixed temperature regulation with some reports of heat retention during warmer months.
Unlike the Snow or Snow Max hybrids that add specialized cooling covers and up to eight layers, the Casper One stays with three foam layers. This keeps the price lower but limits active cooling features.
Public owner reports on forums and retailer listings mention the mattress feels neutral rather than noticeably cool. Shoppers who run hot may want to compare against the Snow Max, which lists at $2,355-$2,880 for queen on sale.
| Model | Type | Queen Sale Price | Height |
|---|---|---|---|
| Casper One | Foam | $599-$899 | 11 in |
| Snow | Hybrid cooling | $1,480-$1,900 | 12 in |
| Snow Max | Hybrid cooling | $2,355-$2,880 | 14 in |
What are current casper one queen mattress prices and sales?
Queen sizes of the casper one mattress currently range from $599 to $899 during mid-2026 sales according to retailer listings. Full prices sit higher, so checking the brand site for active promotions is recommended.
The model ships to all 50 states but not territories or APO boxes. An optional in-home delivery and setup service costs $249 and is non-refundable. Maximum returns per product type are limited to two items.
Refunds process within two weeks to 3-5 business days after pickup, with some payment methods taking up to 15 days. The 100-night trial requires the mattress to remain in donatable condition for free pickup arranged by Casper.
Does the casper one king mattress offer the same trial terms?
Every size of the casper one mattress, including king, comes with the same 100-night trial and 10-year limited warranty. Free pickup applies after the 30-night adjustment period if the mattress qualifies for donation or recycling.
King dimensions follow standard sizing and the 11-inch height remains consistent across Twin through Cal King. Materials stay identical: breathable polyurethane foam, memory foam and high-density base foam under a knit cover.
Owners on brand pages and review summaries often mention the unboxing experience as straightforward because the mattress expands after removal from the compressed box. Edge support receives mixed comments, with some noting it feels softer than hybrid models.
Which sleep positions suit the casper one mattress best?
The medium-firm feel of the casper one mattress works for many side and back sleepers according to aggregated owner feedback. The zoned support in the foam layers aims to keep the spine aligned without excessive sink.
Stomach sleepers sometimes report the need for more pushback and may prefer firmer hybrids such as the Dream model priced at $1,210-$1,395 for queen on sale. The Casper One remains an all-foam construction without coils.
Persistent pain is not addressed by any mattress. Shoppers with ongoing discomfort should consult a clinician rather than rely on bedding changes alone. The American Chiropractic Association endorsement applies only to Dream Max and Snow Max models.
How does casper one mattress review feedback describe durability?
Owner themes on Trustpilot, BBB and NapLab tests note occasional sagging concerns after several years of use. The 10-year limited warranty covers visible indentations greater than one inch when the mattress stays on a proper foundation.
Casper mattresses are designed and assembled in the United States. All current models use CertiPUR-US certified foams. The Casper One carries the same warranty length as higher-priced hybrids in the line.
Maximum returns remain capped at two items per product type. Returns outside the trial window or exceeding the limit are not accepted. In-home setup remains optional and non-refundable at $249.
