A superb mattress, excellent vaue. Relatively light, gel on top, took 2 days to inflate to full size, this is a great product. Ultra comfy, the exact level of firmness I sought, not rock solid yet not softy either. No fibreglass, no accompanying odors, this is the perfect selection, having scanned dozens of mattresses prior to purchasing. For this kind of price getting such premium mattress, look no further, you have found it! Highly recommended.
