We've seen these mattresses drop in price before as part of a one-day sale at Amazon, but they never hit this low. Right now you can pick one up for as little as $209.99 when you clip the $300 off coupon that is on the page. The options in this sale include:

These mattresses are constructed with a 3-inch top layer of gel memory foam and seven inches of base foam. They are shipped to your home vacuum-packed in a box, and you can try it for 120 nights to make sure you like it. If you do like it, eLuxurySupply also makes bed frames for every size mattress.
