Thick Cloud. It is nicely soft and responsive to  body weight. Never had a Gel Mattress before. And I will be replacing my traditional mattress with a new Gel one. 

Delivery from Wayfair was a dream. Nicely packed into a neat cardboard box. But the best thing is the tool that came with the package. The company thought of everything. Most gel mattresses are returned way before anyone sleeps on them. Why? Because customers accidentally cut into them when attempting to remove them from the plastic airtight bag! But the company provides a simple  $1 tool that saves the day.
