Memorial Day weekend is just a few days away. But that hasn't stopped mattress manufacturers from announcing their best Memorial Day mattress sales. [Currently, Serta is offering up to $400 off the iComfort mattress and up to $600 off the Serta Motion Perfect Base. The discounted iComfort mattress (queen) is $1,199, which is a $200 discount and the best deal of the year on a Serta mattress. And if you buy the Serta Motion Perfect Adjustable Base (queen) for $1,399, you get an additional $300 off, for a total savings of $500 (by the way, Serta was only $200 off during Presidents' Day).

If you want the best mattress in the Serta lineup, you can't go wrong with the iComfort line. iComfort is designed to keep you warm and cool at the same time, and provide good back support. The base model (iComfort Limited Edition) features a cold touch cover with cooling gel and cooling foam. The cooling foam conforms to the body to provide maximum support. Meanwhile, the gel promotes breathability and keeps you cool at night.

Like all Serta mattresses, it comes with a 120-day trial period and a 10-year warranty, and when combined with the Serta Motion Perfect Adjustable Base, you can maximize your savings.

The Serta sale ends June 7. Be sure to check out the Memorial Day sale deals for non-mattress deals.
