I tried the Casper Original Foam mattress and found it balances comfort and support. The mattress feels soft around my shoulders but firmer under my hips, which helps keep my spine aligned at night.
Airflow through the foam layers kept me cool enough, though it isn’t a chill mattress. The mattress took a couple of days to fully expand after unpacking, which is normal with memory foam.
Over time, the mattress stayed firm and did not sink or feel too soft. The stretchy cover lets me feel the layers beneath, which adds to the comfort.
Overview of the Casper Sleep Original Foam Mattress
I slept on this foam mattress for some time and found it offers a good mix of softness and support. The mattress feels firmer around my hips and lower back, which helps keep my spine straight.
Around my shoulders, it’s softer and eases pressure. The mattress feels breathable and keeps me from getting too hot at night.
It took a day or two to fully expand after unpacking, but once set, it held its shape well. The mattress feels a bit firmer than other memory foam mattresses I’ve tried.
This mattress is a solid choice if you want medium-firm support and zoned comfort without coils.
Key Features
After sleeping on this mattress for a few weeks, I noticed it balances comfort and support in a way that helps my body feel better. Some parts of the mattress feel softer, while others are firmer, which keeps me comfortable and supports my spine.
ZonedSupportTM Targeted Support
The mattress includes a system that changes firmness in certain areas to support the body better. Around my shoulders, it feels softer and reduces pressure when I lie on my side.
Near my hips and lower back, the foam is firmer, giving me better support to keep my spine straight. I tossed and turned less because of this design.
If you move a lot at night, you might notice the firmness changes when shifting positions.
Breathable Open-Cell Foam Layers
The mattress stayed cooler than many memory foam beds I’ve tried. The foam has tiny air pockets that let heat escape, which helps me stay comfortable.
The breathability also makes the mattress feel less heavy and dense. On very warm nights, it still traps some heat, but overall it’s better than traditional foam.
CertiPUR-US Certified Materials
The CertiPUR-US certified materials gave me confidence about safety and quality. The foams don’t contain harsh chemicals or harmful substances.
There was low off-gassing when I first unpacked the mattress, so the smell was mild and disappeared within a day. This was important to me because I’m sensitive to strong odors.
Durable Base Foam
A solid base foam layer keeps the mattress stable and prevents sagging after long use. After a month, I haven’t seen any dips or loss of shape.
The base foam supports the softer upper layers well, helping the mattress last longer. The 11-inch thickness is decent, though those used to thicker mattresses might want something taller.
Pros and Cons
Trying this mattress gave me a clear sense of its strengths and weaknesses. It fits well in many rooms but also has a few drawbacks worth noting.
Pros
The comfort level stood out right away. The mattress balances softness and support well, especially around the shoulders and lower back, which helped reduce pressure for me.
The zoned support design made a noticeable difference for spinal alignment. Breathability is better than other memory foams I’ve used.
The open-cell foam helped regulate temperature, keeping me cooler at night. The mattress is made without harsh chemicals, which is good for health-conscious buyers.
Setup was easy. The mattress expanded to full size within a day or two, and it didn’t have a strong smell.
Cons
The medium-firm feel might not suit everyone. If you prefer firmer or very soft beds, this one might feel too in-between.
The mattress can take up to 72 hours to fully expand, and in cooler rooms, it stretched out slower. That can be inconvenient if you need it ready for use quickly.
Very tall or heavy users might find it less durable over long periods. Longer-term performance can vary by user weight and size.

Sleeping Experience and Comfort
When I first tried this mattress, I noticed it hits a nice balance—not too soft, not too hard. The memory foam cradles my body well, especially around my shoulders and hips, which usually get sore on other beds.
It offers steady support without feeling like I’m sinking too deep. The Zoned Support design helps keep my back aligned, reducing stiffness in the mornings.
It might feel a bit firm for those who prefer a softer, cloud-like feel. It took a few nights to fully adjust, which is normal with foam mattresses.
My sleep quality improved. I toss less and wake feeling rested. For a medium-firm mattress, it provides solid comfort for different sleeping positions.
Conclusion
I used the Casper Original foam mattress for a while. It balances comfort and support well.
The mattress feels medium-firm and supported my back. The zoned support helped keep my spine aligned.
If you want a very soft or very firm mattress, this may not suit you. It also needs some time to fully expand after opening.
