Most of a Queen dual-chamber Sleep Number Classic (model EFCS4W-2, 2010ish). Includes: foam sides/top/bottom/middle, plastic corner connectors for foam, bottom/side outer cover, 2 single air chambers + 1 extra single air chamber, 1 air chamber cap, inner foam topper, pump and remote. One chamber has started deflating partially overnight and I don’t want to troubleshoot anymore, but if you're a DIYer it probably has a few years left. No bugs, smoke, or pets. Does not include top of mattress cover. Putting it on curb Sunday 8/24 at 6 pm near Arrow Linen on Prospect Ave in South Slope.
