Purple mattresses are known for their unique "Purple grid" layer, which is created from Purple's patented Hyper-Elastic Polymer foam. The grid is a dynamic, hyper-elastic gel-like material that adapts and flexes underneath your body. It's designed to provide pressure-relief and support right where you need it. It also provides extra airflow, which means you'll sleep cool every night. 

In real world talk, that means you'll feel like you're floating on tiny pockets of air when laying down on this mattress. That said, the bed still offers full-body support no matter which sleeping position you assume. I'm alternate between back and side sleeping and I find the mattress to be comfortable in both positions (it's worth paying attention to your sleep position if you're struggling with back pain – our articles on back sleeping, side sleeping and stomach sleeping will explain further). 

It's worth noting that because this is a memory foam mattress, its edge support isn't the best. When sitting on the edge of the mattress, you'll sink in. Otherwise, the rest of the mattress is very supportive. 

Purple includes a 100-night risk-free trial, giving you just over three months to decide if it's right for you. If you're not satisfied with it after 21 days (Purple's minimum trial period), you'll get a complete refund and be able to return it for free. Otherwise, you can keep the mattress and be backed by a 10-year warranty.
