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.

Firm but not too firm.

[This review was collected as part of a promotion.] Serta’s Hello Dreams Firm mattress is firm, but not too firm. The mattress doesn’t give way on the edges like some mattresses do. So you can really utilize all of it. Besides the comfort factor I love the blue edging which will look crisp and clean for years to come.
