Best Time to Buy a Mattress: Memorial Day Isn't the Answer

Ask anyone when to buy a mattress and they’ll say “Memorial Day.” It’s the most repeated piece of conventional shopping wisdom in this category, and it’s not exactly wrong — but it’s also not the answer for most shoppers in 2026.

The truth is that the mattress market split into two categories around 2014, and the “best time” depends entirely on which one you’re shopping in:

1. Online direct-to-consumer brands (Casper, Nectar, Purple, Saatva, DreamCloud, Brooklyn Bedding, Tuft & Needle, Helix). These are nearly always “on sale” with little real seasonal variation.

2. Traditional in-store brands (Tempur-Pedic, Stearns & Foster, Sealy, Beautyrest, Sleep Number, and mattress retailers like Mattress Firm and Macy’s furniture). These follow the four-tentpole holiday calendar — and Labor Day, not Memorial Day, is the deepest.

Let’s break each down.

Online direct-to-consumer: “best time” is a myth

If you’re shopping Casper, Nectar, DreamCloud, Purple, Saatva, Tuft & Needle, Helix, or any of the dozens of similar online-first brands, here’s the truth: they are always running a promotion. The promotion’s name changes month to month (“New Year Sale,” “Memorial Day Event,” “Summer Sleep Refresh,” “Anniversary Sale”), but the actual delivered price varies by typically 5–10% across the year.

You’re not waiting for a magic moment. You’re choosing between promotions.

What to do instead:

• Compare the delivered price after all promotions and codes, not the discount percentage. Brands quote 50% off an inflated MSRP that nobody pays.
• Look for stackable codes. Many DTC brands have a brand-specific 5–10% code that works on top of the on-page promo. Search “[brand name] coupon Reddit” — the deals subreddit usually has the current codes.
• Trial period and return policy matter more than the discount. A 100-night trial with free return shipping is worth more than 5% off without one.
• Check the warranty. A 10-year sagging warranty is standard. Less than that is a yellow flag.

Traditional in-store: the four-tentpole calendar

For Tempur-Pedic, Stearns & Foster, Sleep Number stores, Mattress Firm, and similar in-store brands, the calendar is real:

1. Memorial Day weekend

The classic. Solid discounts (15–25% off), free accessory bundles. Not the deepest, but the first major sale window of the year.

2. July 4th weekend

Roughly equivalent to Memorial Day. Slightly deeper for some brands, slightly shallower for others.

3. Labor Day weekend

The deepest mattress sale of the year, particularly for premium brands. Tempur-Pedic specifically uses Labor Day for its annual “clearance to make way for new models” event. This is when in-store flagships hit their floor.

4. Black Friday / Cyber Monday

Strong for accessories (sheets, mattress protectors, pillows, adjustable bases) and for budget-tier mattresses. Premium in-store brands typically don’t discount as deeply as Labor Day — but they do discount.

When NOT to buy in-store

• January through April (between Black Friday and Memorial Day): nothing notable happens.
• The exception: new model launches, which happen in late spring (April–June). When the new line arrives, last year’s models hit clearance. This is a sleeper window for in-store deals.

Tactics for in-store shopping

Always ask about floor models. Showroom mattresses are typically discounted 20–40% off. They’ve been laid on by hundreds of people, but they’ve never been slept on. For most people, that’s fine.

Ask about last year’s models specifically. “Do you have any of the [last year’s model line] still in stock?” — sales associates almost never volunteer this, but the answer is often yes, and the discount is real.

Negotiate on the bundle. Mattress retailers’ “Black Friday Bundle” might include a free adjustable base or pillows. Ask if they can substitute the bundle items, throw in free white-glove delivery, or apply the bundle value as cash off the mattress price.

Match online to in-store. Tempur-Pedic and Sealy are sold both online and at Mattress Firm. The online manufacturer price often matches or beats the store. Walk into the store with the online price loaded; ask them to match.

Mattress accessories: different calendar

Sheets, pillows, mattress protectors, adjustable bases, and bed frames follow a different cycle:

• Best window for accessories: Black Friday / Cyber Monday. Adjustable bases see 40% discounts; mattress protectors and sheets at deep loss-leader pricing.
• Second-best window: Amazon Prime Day for accessories.
• Worst window: April–May, before any major sale.

If you’re buying a mattress in May, hold off on the accessories until November.

What if you need a mattress now?

If your current mattress is genuinely failing — visible sagging, body impressions deeper than 1.5”, waking up sore — you should not wait for the perfect sale window. Mattress quality affects every single day. Buying now from an online DTC brand gets you about 90% of the savings you’d get by waiting six months, with none of the back pain.

The “best time” rules matter for planned purchases. For replacement urgency, buy now.

TL;DR

• Online DTC (Casper, Nectar, Saatva, etc.): Any time. The promotions are continuous. Focus on delivered price, not the percentage banner.
• In-store premium (Tempur-Pedic, Stearns & Foster, Sleep Number): Labor Day for the deepest, Memorial Day or July 4th for solid.
• Accessories: Black Friday.
• Replacement urgency: Right now from a DTC brand with a 100-night trial.

Stop waiting for Memorial Day specifically. It’s one window of four, and it’s not the deepest one.
