I am very interested in the “Purple” mattress, if anyone has any experience with that…
Bought a queen-size Casper for our daughter’s room a couple of years ago, using it with an Ikea platform bed. Now that she’s graduated college and moved away, it’s our guest bed. She has lower back issues, but finds the bed quite comfortable. I’ve rested on it briefly just to try it, but never slept on it. Seemed pretty good to me.
It’s springy foam with a memory foam core, but is still fairly firm. When we unfurled it, there was virtually no outgassing odor. It was considerably easier to get up the stairs and into the bedroom than a conventional mattress would’ve been. (Given how brutal it was to assemble the Ikea platform, I suspect we will include the bed with the house when we get to the point in our lives where we need to downsize.)
Cost was $800 with a discount code ($50 off), including shipping. They did not collect sales tax at the time (unless you lived in NY, I think).
