The Allswell mattress is an entry-level hybrid model made by Walmart as part of its ‘affordable luxury for sleep and wellness’ range. With a queen size retailing for just $337, The Allswell is aimed squarely at the budget end of the American mattress market. In fact, it’s rare that we find a hybrid (springs and memory foam) for such a cheap price, so how good can The Allswell really be compared to the very best mattresses on the market?
