The SleepSoul Air mattress uses coils to provide excellent support, helping you drift quickly into a relaxing sleep. Luxurious comfort quilting and a soft foam layer sit on top of a traditional open-coil spring system. Combined, these features create the perfect balance of comfort and support, allowing you to sleep peacefully in any position. So whether you're a toss-and-turner, a duvet hogger or a belly flopper, you're guaranteed a comfortable night's sleep with SleepSoul. By distributing your weight evenly across the mattress, the coil-sprung mattress prevents the dreaded roll-together' effect. Whether you sleep alone or with a partner, you'll remain stable and supported throughout the night. The Air mattress comes rolled up for your convenience. Simply unroll, remove the plastic wrap and wait for your mattress to take shape. In 2 hours, it will be good; in 24 hours, it will be great. 1 - Soft/Medium
