Allswell Performance
As shown above, Allswell got green scores across the board, except for motion transfer.
This hybrid mattress has a high level of motion transfer, meaning it’s not ideal for people who sleep with a partner. The movement on one side of the bed can be felt on the other side, which may cause discomfort.
So, if one partner gets in and out of bed at night, the other person may be disturbed by the motion. This aspect is especially problematic for light sleepers, but not so much for heavy sleepers.
Apart from that, the Allswell Cool mattress offers excellent value for the money. Not only does it cost more than 50% less than the average hybrid mattress ($1,383), but it also has an extremely fast response time and a high bounce.
