How firm or soft should I make the Organic Serenity mattress without trying it?

If you really don’t know what your needs are, we recommend a medium Dunlop mattress. We would recommend configuring it this way: bottom layer Firm, middle layer Medium, and the top layer Soft. If you are getting a Queen or larger mattress, we recommend ordering it with all layers split (6 pieces total) for versatility. In this way you have maximum flexibility in terms of testing the mattress. You can make it really firm with Firm-Firm-Medium (Firms on the bottom) or pretty soft with Medium-Soft-Soft (Medium on the bottom). If you do an exchange, you’ll know exactly what you want from switching things around before you tell us which replacement layer(s) to send you.
