Whether you’ve been having trouble sleeping at night or you’ve simply come to terms with the fact that the old mattress you’ve been sleeping on for more than a decade now is ratty and gross, Amazon is hosting a killer one-day sale that you need to check out. On Monday only, Amazon is slashing a whopping 30% off the price of Nectar Memory Foam Mattresses in every available size. Twin mattresses cost just $349.40 right now and you can bump up to Full for just $489.30. Queen is of course the most popular size that Nectar makes, and you can snag one for $559.30 instead of $800. Want to upgrade to a King? It’ll only cost another $100!

Here are the bullet points from the product page:

  • #1 FASTEST GROWING BRAND IN THE U.S. – Recognized as the fastest growing e-commerce retailer by Internet Retailer, Nectar is a memory foam bed-in-a-box mattress designed for every kind of sleeper. Nectar is part of the Resident House of Brands.

  • IDEAL SUPPORT FOR ANY POSITION – Optimal level of firmness, coolness, breathability, and comfort. Nectar molds to your body, relieving all your aches and pains.
