The W Store
knocks 40% off
with no minimum required via coupon code "WX4T7". That's tied for the best percent-off coupon we've seen this year from The W Store, which is the storefront for W Hotels and sells apparel, accessories, and bedding. This coupon does not apply to sale items.
A best bet is The W Bed Queen Plush Top Mattress for $1,099 before coupon, $659.40 after. With free shipping, it's among the lowest total prices we've seen for the bed.
