Where to Buy an Olympic Queen Mattress (66×80)

What Is an Olympic Queen Mattress?

An Olympic Queen measures 66 inches wide × 80 inches long — exactly 6 inches wider than a standard Queen (60×80) but 10 inches narrower than a King (76×80).

Olympic Queen fills the gap between Queen and King — 6 inches of extra sleeping space without needing a larger bedroom.

The Olympic Queen was introduced in 1999 as a middle ground for couples who wanted more space than a Queen but couldn't fit a King in their bedroom. It never became a standard industry size, which is why finding one today requires knowing where to look.

Why Olympic Queen Mattresses Are Hard to Find

Walk into any mattress store and ask for an Olympic Queen. Most salespeople won't know what you're talking about.

The mattress industry standardized around five sizes: Twin, Full, Queen, King, and California King. Olympic Queen exists outside that system. Retailers don't stock it because demand is low. Demand stays low because retailers don't stock it. It's a cycle that leaves Olympic Queen owners without options.

From what I see in my removal work, this creates a real problem. I've picked up Olympic Queen mattresses that were 15, even 20 years old — sagging, body impressions permanent, foam completely deteriorated. The owners knew the mattress was shot. They just didn't know where to buy a replacement.

An Olympic Queen I removed after 18 years of use. The owners had been looking for a replacement for 3 years before finding one online.

The good news: quality Olympic Queen mattresses exist. The same manufacturers making mattresses for standard sizes also make them in 66×80. You just have to know where to look.

Who Needs an Olympic Queen?

Based on the Olympic Queens I've removed over the years, owners typically fall into three categories:

Couples in smaller bedrooms — A King won't fit, but a Queen feels cramped. The Olympic Queen provides meaningful extra space without requiring a larger room.

RV and camper owners — Many RVs, especially higher-end models, come with Olympic Queen beds. When the factory mattress wears out (and they always do), you need an exact replacement.

People with existing Olympic Queen frames — Often inherited furniture, vintage beds, or frames purchased when Olympic Queen was more common in the late 1990s and early 2000s.

Where to Buy Online

Online is where you'll find the widest selection of Olympic Queen mattresses. These retailers specialize in custom and odd sizes, which means they actually stock 66×80 options rather than treating them as special orders.

Where to Buy In-Store

Finding an Olympic Queen mattress in a physical store is difficult but not impossible. Here are your options:

What About Big Box Stores?

Mattress Firm, Sleep Number, Tempur-Pedic stores: These retailers focus on standard sizes. Olympic Queen is not part of their inventory. Don't waste a trip.

Costco, Target: Online listings may appear for Olympic Queen, but selection is extremely limited or nonexistent. These retailers aren't reliable sources for this size.

What I Look for in an Olympic Queen Mattress

Because Olympic Queens are harder to find, people often settle for whatever's available. That's a mistake. I've removed Olympic Queens that lasted 20+ years and ones that fell apart in 3. The difference comes down to what's inside.

Here's what I check when evaluating an Olympic Queen — the same criteria I use when tearing open mattresses to see how they're actually built.

Foam Density in the Comfort Layers

The comfort layers are the top 2-4 inches of foam you sink into. This is where cheap mattresses fail first. I've torn apart hundreds of Olympic Queens where the comfort foam has completely deteriorated — turned to dust, crumbled apart, or compressed into a hard pancake.

What separates the survivors from the failures? Foam density. Memory foam should be at least 4 lb/ft³. Polyfoam should be at least 1.8 lb/ft³. Anything lower breaks down fast. Most mattresses that show up at my facility with body impressions have comfort foam under these thresholds.

The problem with Olympic Queens specifically: because they're custom sizes, some manufacturers use whatever foam they have on hand rather than maintaining the same specs as their standard sizes. Ask about foam density before you buy. If a retailer can't tell you, that's a red flag.

Support Core Construction

The support core is everything below the comfort layers — usually either high-density foam or pocketed coils. This is what keeps the mattress from bottoming out and provides the foundation for everything above it.

In the Olympic Queens I remove, support core failure shows up differently depending on construction:

• All-foam mattresses: The base foam compresses unevenly, creating a trough in the middle where both sleepers roll together. I see this constantly in foam mattresses under 10 years old.
• Innerspring/hybrid mattresses: Coils hold up better long-term, but cheap coils lose tension and start to poke through. The best hybrids use pocketed coils (individually wrapped) rather than connected coil systems.

For Olympic Queens specifically, coil count matters more than in standard sizes. You're adding 6 inches of width — that's more sleeping surface that needs support. A mattress with the same coil count as its Queen version is actually giving you less support per square inch. Look for manufacturers who scale their coil count proportionally.

Edge Support for the Extra Width

Here's something specific to Olympic Queens: you're buying this size for the extra sleeping space. But if the edges collapse when you sit or sleep near them, you lose that space.

I've removed Olympic Queens where the owners complained they still felt cramped — turns out the edge support was so weak that the usable sleeping surface was barely larger than a standard Queen. The extra 6 inches just rolled them toward the middle.

Reinforced edge support (foam encasement or reinforced perimeter coils) keeps the full 66 inches usable. This matters more on an Olympic Queen than on standard sizes because edge sleeping is often why people chose this size in the first place.

Materials That Actually Last

Based on what survives longest at my facility:

• Natural latex outlasts everything else. I've removed 20-year-old latex mattresses that still had life in them. It's more expensive upfront but the longevity is real.
• High-density memory foam (4+ lb/ft³) holds up well. The cheap stuff (under 3 lb/ft³) is what I see falling apart.
• Pocketed coils maintain their support better than connected coil systems. The individual wrapping prevents the "domino effect" where one weak coil affects the ones around it.

What fails fastest: low-density polyfoam (under 1.5 lb/ft³), cheap memory foam, and anything with fiberglass fire barriers that can escape through the cover.

Why This Matters More for Olympic Queens

With standard sizes, if you buy a bad mattress, you can replace it easily. With an Olympic Queen, you're committed. Finding a replacement is work. The people I pick up from who've had their Olympic Queen the longest aren't just lucky — they bought quality construction in the first place.

How to Choose the Right Mattress

Construction Types

Hybrid (coils + foam): Combines pocketed coil support with foam comfort layers. Sleeps cooler than all-foam due to airflow through the coil unit. Good motion isolation and edge support.

Memory Foam: Conforms to body shape and provides pressure relief. Can sleep warm. More affordable than hybrids. Lighter weight — easier to move into RVs.

Latex: Naturally bouncy and responsive. Sleeps cooler than memory foam. Extremely durable — I see 15+ year old latex mattresses still in good shape. More expensive.

Innerspring (pocketed coil): Traditional bounce feel with modern pocketed coil technology. Good airflow. Firmer support than foam options.

Firmness Guide

Here's a quick reference. For the complete breakdown including body weight considerations and ILD ratings, see my full firmness guide.

What I Look For

Based on removing over 1 million mattresses, here's what separates mattresses that last from those that fall apart in 3-4 years:

Foam density matters. Low-density foam (under 1.5 PCF) breaks down quickly. High-density foam (2.0+ PCF) holds up for years. Ask about density or look for specs that mention "high-density support foam."

Low-density foam (1.2 PCF) after 4 years — completely deteriorated

High-density foam (2.0+ PCF) — firm support that holds up for years

Coil gauge matters. In hybrid and innerspring mattresses, lower gauge numbers mean thicker, more durable coils. 15-gauge is solid. 18-gauge is flimsy.

18-gauge coils — thin and prone to sagging

15-gauge coils — thicker wire, better long-term support

No fiberglass. Many budget mattresses use fiberglass as a fire barrier. If the tag says "do not remove cover," it likely contains fiberglass. Avoid these. Look for CertiPUR-US certification and brands that explicitly state they're fiberglass-free.

Olympic Queen Accessories

• eBay: Various options

Tip: King sheets (76×80) will fit an Olympic Queen but will be loose on the sides. For a proper fit, order the correct size.

Bed Frames

Olympic Queen bed frames are less common than the mattresses. Options:

• Adjustable bases: Many adjustable bases can accommodate Olympic Queen. Check manufacturer specs for maximum dimensions.
• Platform frames: Some manufacturers offer Olympic Queen or can adjust standard sizes.
• Custom frames: Local furniture makers can build to your exact specifications.

Mattress Protectors

Search "Olympic Queen mattress protector 66x80" on Amazon. Several brands offer waterproof and hypoallergenic options in this size.

What to Do With Your Old Mattress

When you buy a new Olympic Queen online, you're left to figure out what to do with the old one.

The reality: Olympic Queen mattresses are harder to dispose of than standard sizes. Most donation centers won't take them (odd size + mattress donation restrictions). Landfills may charge extra. And you can't fit a 66×80 mattress in most vehicles.

Our crews pick up mattresses of all sizes — including Olympic Queens — for recycling.
