Via Slickdeals.net, the W Hotels Store is offering 40% on their beds and bedding through May 31 with promo code WE4XT.
I got in on a similar offer back in March, and am very pleased with my purchase. My understanding is that W properties use the plush top mattress with a featherbed, rather than the softer pillowtop that’s also on sale here. But preferences will vary.
