Designer Living offers 30% off a selection of pillow pads, mattress pads, and sheet sets. (If the discount doesn't automatically apply, use coupon code "BASIC30".) That's the best discount we've seen specifically on these items from Designer Living. (We saw up to 83% off plus an extra 30% off select items, including some of these items, three weeks ago.) Shipping starts at $5.95, or get free shipping on orders of $75 or more. Some exclusions may apply. Offer ends March 10.

A best bet is the Sleep Philosophy Smart Cool King Pillow Pad with Pillow Cover in Blue (pictured) bundled with a $1.15 Designer Living Credit for $32.99 before the above discount, and $23.09 after. With $5.95 for shipping, that's $10 off and the lowest total price we could find. This gel pad purportedly stays cool for up to four hours.
