How long does it take for a Casper mattress to expand after unboxing?

When a Casper mattress is unboxed, it typically takes about 24 to 48 hours for it to fully expand and regain its intended shape. After being compressed during shipping, the mattress may initially appear thinner and may take some time to decompress completely. Although some individuals may notice that their mattress achieves a significant level of expansion within the first few hours, it is advisable to allow a full day or even two for optimal results. The optimal characteristics of the mattress, including firmness and support, are best experienced after it has had adequate time to adjust to the environment. This is particularly important if the mattress has been exposed to temperature fluctuations, as temperature also affects the expansion process.
