Sleep Number Queen Mattress for $1,799.99

Costco is offering the Sleep Number Ultimate 12" Mattress (Queen) for $1,799.99, down from $2,300. This represents a savings of $500, or approximately 21.7% off the original price. The deal includes free shipping and is available to members. While the discount is notable, it is close to the typical retail price for Sleep Number mattresses, and the price drop is modest compared to other promotions on similar products. This deal is worth considering if you're a Costco member and shopping for a high-end mattress, but it isn't an extraordinary discount compared to past sales.
