Overstock drops the Serta Ultimate 4" Memory Foam Mattress Topper from $179.99 to $129.99 through Memorial Day Weekend. Better yet, new customers can activate this link to cut it to $123.49. With $2.95 shipping, that's $49 under the lowest price we've seen all year and the lowest price for this topper in all sizes by at least $60. It is available in twin, full, queen, king, or California king for this same price. There is no sales tax.
