Warnings and disclaimers

Disclaimer

Urethane foam will burn if exposed to an open flame or other sufficient heat source. Do not expose urethane foam to open flames or any other direct or indirect high temperature ignition sources such as burning operations, burning cigarettes, space heaters or naked lights. Once ignited, urethane foam will burn rapidly; releasing great heat and consuming oxygen at a high rate. In an enclosed space the resulting deficiency of oxygen will present a danger of suffocation to the occupants. Hazardous gases released by the burning foam can be incapacitating or fatal to human beings if inhaled in sufficient quantities. Once ignited, urethane foam is difficult to extinguish. Foam fires that appear to be extinguished may smolder and reignite. Always have fire officials determine whether a fire has been fully extinguished.

So far so good

My wife and I have had a few different boxed mattresses -- this one, so far, seems to be the best quality. I like a firm mattress and she likes a plush. This one seems to suit us both fairly well. Time will tell as our last one (different brand) began go sag where we slept.

Sooooo comfy!

We got this for our 4 year old a little over 6 months ago and it's amazing. He honestly has the most comfy bed in the house! Our 5 year old asked to have the same one since it's so much more comfortable, so here I am searching through the order history to purchase another! I'm thinking this will be replacing our sleep number soon…the cost is unbelievable considering how comfortable it is.
