Cyber Monday lands on November 30, 2026 — the Monday after Thanksgiving — and it’s quietly one of the best days of the year to buy a mattress online. While Black Friday grabs the headlines, Cyber Monday is where the online-only doorbusters and bed-in-a-box deals tend to hit their lowest prices. Here’s what to expect and how to shop it well.
When is Cyber Monday 2026?
Cyber Monday 2026 is November 30. In practice, most mattress brands don’t wait for the single day — they run “Cyber Week” pricing that starts the Friday before (Black Friday, November 27) and rolls through the following week. That means you usually have several days, not a few hours, to lock in the best price without panic-buying.
Cyber Monday vs. Black Friday for a mattress
They run back to back and the prices are close, but the emphasis differs. Black Friday leans toward in-store doorbusters and the widest selection, while Cyber Monday is online-first — which suits mattresses, since the best value now lives with brands that ship a bed compressed in a box straight to your door. If you want an online-only brand or an adjustable-base bundle, Cyber Monday is often where the single lowest price shows up. If you’d rather feel a mattress in a store first, lean Black Friday. Our Black Friday mattress deals guide breaks down that side.
How deep are the discounts?
Black Friday and Cyber Monday together make up the second-biggest mattress sale window of the year, behind Memorial Day. Expect discounts in the range of roughly 25% to 35% off on many mattresses, with the best bundle pricing of the year on mattress-plus-base packages and free accessories (pillows, sheets, protectors) thrown in. The headline percentage matters less than the out-the-door total, so compare the final price including any bundled extras.
What to buy — and what to skip
Cyber Monday is the moment for the big purchases: a new mattress, an adjustable base, or a mattress-and-base bundle, where the dollar savings are largest. Accessories are cheap year-round, so don’t let a small discount on sheets or a pillow talk you into a bigger cart. And don’t chase the deepest percentage onto the wrong mattress — a great price on a feel that doesn’t match how you sleep is still a mistake.

How to get the best Cyber Monday deal
- Subscribe to brand email lists now — many send early-access Cyber pricing a day or two before the public sale, before popular sizes sell out.
- Check the sleep trial and return window — the best bed-in-a-box brands include a trial of 100 nights or more, so a sale purchase isn’t a gamble.
- Compare the total, not the percentage — factor in bundled base, pillows, and shipping to see the real value.
- Buy early in the window — Cyber Week pricing usually holds for days, so there’s no need to wait for the exact Monday and risk a sellout.
