We bought the Octasmart Hybrid mattress 5 weeks ago, having had to return a mattress made by one of your competitors, as it was too hard and was exacerbating existing back problems. The Octasmart is much softer and therefore, eases pain and tension in neck and shoulders, while still managing to support the rest of your body comfortably. We would say we're happy with the mattres but are surprised at the absence of handles, which make it very difficult to rotate. For the price, we think handles should be included.
