The W Hotel Store takes 30% off all bedding via coupon code DREAMS through 7/15. This can be used on The W Bed, the plush-top mattress made exclusively for W Hotels by Simmons. Queen-size is $1099 but just $769 after the code (king is $1299 or $909 after the code). This is the best deal in some time. Plus, delivery is free. The W Store also sells other bedding and home accessories, as well as apparel. Of note: I ordered this myself over a year ago; the bed is great and delivery is quick.
