• Shop the Amerisleep summer sale 

Amerisleep has five mattresses: the entry-level AS2, a medium-firm mattress that's perfect for back sleepers; the mid-range AS3, which is great for all sleep styles; and the high-end AS5, which adds Active Flex and offers the softest sleep. There's also the firm AS1, and the medium-soft AS4 (aimed a those who sleep on their side). 

All designs are built from plant-based Bio-Pur memory foam, which has an open-cell structure that's more responsive to pressure than traditional memory foam, and should stay cool more effectively. If you'd prefer a bit of extra bounce, you can opt for the hybrid version of most the mattresses, for an added coil layer. You've got 100 nights to make sure you absolutely love the mattress before deciding to keep it, and Amerisleep also offers a longer-than-the-usual 20-year warranty.
