5 Year Warranty

The Symbol Marconi is a low-cost, high quality all-foam mattress, that is available in both standard and custom sizes. An additional 1" of Symbol's SUPER SOFT FOAM gives this one a softer feel, in comparison to the 6" Polypedic mattress. The Marconi is made of CERTIPUR-US foam and has a stylish and comfortable quilted cover.

7 Inch All-Foam Quality Mattress

The Symbol Marconi is a very popular mattress all across the United States due to its low price and its combination of comfort and support. It's a bit softer than the 6" Polypedic mattress of a similar build and slightly thicker. While I prefer firmness and this one is technically softer than the 6" Polypedic All-Foam Cheap Mattress by Symbol, I can feel the same support from this model as I do in the aformentioned mattress but have a bit more comfort on this one. This is definitely a great option for anyone on a budget and can be transported rather easy if it's used for such purposes.

Michigan Discount Mattress also offers this one in custom sizes so, it's a versatile piece of sleep technology. If you are seeking a foam sleeping surface simply out of choice and are looking for something with just a bit more softness in its top layers, I'd suggest the Medium-Firm 8.5 Inch Mattress - Kepler by Symbol.
