Casper’s flagship all-foam mattress and the all-foam option from Walmart’s Allswell are both compelling options for mattress shoppers. Both contain memory foam and use materials of certified quality. The mattresses differ a bit in feel, which we will go over in this comparison.
- Both contain memory foam and are both all-foam mattresses.
- Both use CertiPUR-US certified foams, which means their materials are considered more eco-friendly than typical mattress materials.
- Both have 100-night trials and have great customer service.
- Casper is more expensive ($550 to $1,150 for the original Casper, $345 to $585 for Allswell).
- Allswell is thicker (Allswell is 12″ thick, while the original Casper is 10″ thick.).
- Allswell has more of a memory foam feel and is a bit firmer.
- Casper has more of a balanced foam feel and Casper’s top layer is more responsive than that of Allswell.

Allswell Luxe Construction
- The cover of Allswell is made with a woven fabric intended to have cooling qualities. It is also quilted with memory foam to add softness and pressure relief.
- The top layer is 1.5″ of a slow-responding memory foam, which gives the mattress good pressure relief and body contouring.
- The 1″ second layer is comprised of a firm, springy AirFoam material.
- Next is a 3″ transition layer of super soft foam.
- A 5.5″ layer of firm, supportive foam forms the base.
Original Casper Construction
- The original Casper has a lightweight cover that doesn’t affect the feel of the mattress overall too much.
- On top is a 1.5″ thick layer of open-cell polyfoam to give the mattress some bounce and softness.
- The second layer is 1.5″ of memory foam, which gives the mattress extra pressure relief and body contouring.
- The next layer is 1.5″ of polyfoam transition foam. The purpose of this layer is to ensure even weight distribution.
- The base layer is 5″ of high-density polyfoam, which is pretty standard amongst bed-in-a-box mattresses.
- Both have responsive surfaces, though Casper is a bit more responsive.
- Allswell’s memory foam top layer gives it more of a traditional memory foam feel where sleepers slowly sink into the mattress.
- Allswell is a bit firmer and thicker.
- Allswell has a quilted top.
- Casper is a bit more springy and bouncy.
- Both contain memory foam somewhere in the construction.
While both mattresses are responsive, Allswell is firmer and a bit slower moving. Check out the firmness and feel of both mattresses in the videos below.
Motion Transfer Differences
Both isolate motion well, though Casper has a bit of an edge because it is a little softer. Either is a good option for couples. Learn more about motion transfer on each mattress in the videos below.
Pick Allswell If …
- You like memory foam- Allswell’s top layer is memory foam, so you’ll get that memory foam feel.
- You sleep on your stomach- Allswell is a little firmer and more supportive than Casper, potentially making it more appropriate for stomach sleepers.
- You like a firmer mattress- The Allswell is definitely the firmer mattress of the two. If you like a little bit of extra firmness, then the Allswell may be the way to go.
Pick Original Casper If …
- You sleep on your side- If you sleep on your side or switch positions, you’ll prefer Casper’s more responsive and contour-conforming surface.
- You want a balanced foam feel- Casper uses foams that recover faster, so you won’t sink as far into the mattress. It should be easy to move around on this mattress and switch positions at night.
These are two solid mattress options, one from a well known bed-in-a-box maker (Casper) and the other from a well-known brand breaking into the space (Allswell from Walmart.) Hopefully this comparison helped you better understand which is the better option for you.
