I recently tried a Nexgel bed by Natura. It was the basic model with one layer of Nexgel over 8 inches of foam. They didn't say what the foam is and no other specifications are given for the product. I did find it quite comfortable but wondered what the more advanced models would feel like. Unfortunately, the store only had the basic in stock.
I then started web searches for Nexgel and found more disappointing information than I could stand.
I am now thinking of just getting and Inteligel topper for my current bed. Is there a NexGel topper, I can't find one. It might cost less. Don't know how it would stand up compared to Inteli-Gel. I believe these products are over priced, missing a much larger market.
I like the idea of adding a topper to a block of good foam on and advanced slatted bed base. It may work better than on a platform as it would breath and supposedly adjusts to body weight in problem areas.
The trick is getting the right foam for your body weight that is compatible with the topper.
Intelli-gel , orthogel, Nexgel, how confusing!
