A practical savings guide for shoppers using SONU Sleep offers.
SONU did not show a promo code on 27 October 2026. The savings are on the site itself: a Halloween Sale with $500 off every Sleep System, and an extra 6% off for buyers who opt out of the 100-night trial at purchase. The sale banner also mentions 3 free gifts, so check the cart to see which items are added.
On SONU's own scale the Plush is a 4 in firmness, the Hybrid a 6 and the Firm an 8. Every system comes with 4 Support Pillows (2 for a Twin XL) and a set of custom sheets and pillowcases, valued at $294 for a King. SONU says the system is not for children aged 12 or under.
Shipping is free in the continental US; Alaska and Hawaii cost extra, and PO Box and APO addresses cannot be served. Each system has a 100-night home trial, during which SONU collects the mattress and refunds the buyer under its trial terms, plus a 10-year warranty. Old mattress removal can be booked through LoadUp, and removal fees are not refundable. Monthly payment plans are offered through partners at checkout.
