How To Open Casper Mattress


How To Open Casper Mattress Correctly


Let it expand

You have to follow the instructions for the specific Casper mattress you have. However, the main principle is similar, where you have to allow the foam bed to expand. Let’s say that your mattress arrived in a box. 

Our tip is to lift it onto your foundation and then slide the mattress out. You can have one person grab the other end of the rolled mattress. Since the bed is tightly rolled with a plastic sheet, it will have a controlled release and slowly unravel flat. 

Once you have it in the desired position, you can cut open the sealed bag to allow the bed to finish inflating. Casper mentioned that the mattress is usable within minutes after expanding. However, the size of the specific model will influence how quickly it will finish expanding. 


Set it up

Since you can use the Casper mattress after expanding, how should you set it up? First, check if you have the proper size sheets according to your product’s height. Casper offers sheets as well, but you can use any sheet as long as it’s compatible with your bed’s dimensions. 

Casper mattresses range from 11 to 13 inches in height to give you a quick idea. What about the bed frame? The company recommends using their metal frame and Casper foundation. 

Using the appropriate foundation and frame, you can ensure the proper weight distribution and support on the bed. Casper even has an adjustable bed frame if you prefer this feature. But if you have an existing bed frame, you want to ensure that it can support the mattress by having a plywood piece over the slats or beams if necessary. 


How Long Does It Take For A Casper Mattress To Expand?

A Casper mattress will finish inflating after 24 hours. However, you can gauge its overall feel since some users note that the bed was inflated enough even after only an hour. We recommend still waiting after 24 hours to experience the proper comfort and support and prevent the sheets from sliding or wrinkling. 


Can I Sleep On My Casper Mattress Right Away?

The company mentioned that the mattress is ready for use within minutes after you remove the plastic wrap. Be sure to remember our tips in the two-step guide of letting the mattress unroll in the plastic wap after removing it out of the box. Then, remove the wrap once the bed is flat.

You can decide if the mattress has inflated enough for comfortable use. Some users did testify truly on Casper’s claims that the mattress can be slept on within minutes after expanding. You can also use this period for adjustment to help you get used to your new bed. 


How Long Can I Leave My Casper Mattress In The Box?

Let’s say that you can’t immediately unbox your Casper mattress upon arrival. You can feel at ease that the bed won’t lose its structure being left inside the box for a month. However, do note that the 30-night sleep trial starts once your bed is delivered. 

You will only know the bed’s quality and if it’s satisfactory when you use it immediately. But what if you have already unboxed it and you need to store the bed?


How to store Casper mattress

Much like with other brands, Casper recommends having the mattress stored as your secondary bed in guest rooms or extra rooms if you’re not using it. They don’t advise having the mattress as a futon or sofa bed because the models are not meant to be folded. But if you have no extra space or you need to move the mattress, Casper can be propped on its side or against the wall temporarily. 

You can’t compress or roll your Casper mattress like other beds for a longer transit or storage time. Instead, you have to store it flat to ensure that it won’t get damaged.


When to replace Casper mattress

The overall lifespan of your mattress depends on how you use it and care for it. It can take ten years before needing replacement because of the way Casper layer the materials. However, you want to do practices to ensure that the mattress will last longer and not get worn down quickly. 

To even out the usage and pressure the mattress experiences, you can rotate your bed in a consistent schedule. We also encourage you to check the frame and foundation you use if they’re still supporting the mattress properly. 



So your Casper mattress has just arrived. If you’re unsure how to open Casper mattress from the box, it’s as simple as letting it unroll and then removing the wrap once it’s flat. The good news with this product is you can use it minutes after expanding.
