Review: Great mattress. - Very comfortable. Not too soft.
Review: You won't be sorry. - Consistently comfortable, supportive, and unlikely to disturb your sleep when your spouse rolls over, Casper Sleep Element Full Mattress gets 5 stars from me! I am slowly transitioning all our family's mattresses to Caspers, and now have purchased 5 total. The convenience of it's arrival in a box is a wonder! It is tightly wrapped and vacuum packed into a plastic bag, so it was OK when we didn't get the delivery right away and it was outside for a few days. You have to open it and let it expand before you use it. I have heard that the "gasses" involved are not great to breath so always leave it in an empty room inflating/degassing for a day or two before use, but a recent Google didn't turn up any further info on that, so maybe it was just put out by the haters.

## Questions & Answers

**Q: How does it do in the cold unheated bedroom ?**
A: Hi there! Whoile foam can become stiffer in freezing temperatures you should not experience anything like this in a slightly colder room.

**Q: Is the 100 night trial return on new model as well?**
A: They expect customers to deflate and put the decompressed mattress back in a box and don’t offer pickup service at all! Do not buy from Amazon

**Q: How much does the king mattress weigh?**
A: It weighs 87 pounds.

**Q: What is the exact length of the full? They always say 75, but in reality it varies quite a bot. I need a 74" or less.**
A: Hi there! The dimensions of the Element size-full are 75"x 53" x10". Unfortunately, if you are in need of something that is 74" this would not be the right fit.

### ⭐⭐⭐⭐⭐ Still sleeping soundly
*by B***A on October 2, 2025*

We really like this mattress so far. Been using it for a month. It’s an economical choice that’s comfortable. Firm enough to not sink in too far, yet not too hard for our 50 year old bodies.
