Tempur-Pedic Twin Mattress Dimensions, Explained

You want the size, not a sales pitch. I get it. Here’s the thing—Tempur-Pedic keeps sizing simple, but thickness and fit can trip people up. I’ll walk you through the essentials, what actually fits, and a couple of gotchas most folks don’t learn until sheet-shopping day. And yes, I’ll keep the phrase you searched—tempur pedic twin mattress dimensions—in plain view without the jargon.

The quick answer: the numbers you came for

A standard Tempur-Pedic Twin measures about 38 inches wide by 75 inches long. The Twin XL is the same width, 38 inches, but stretches to 80 inches long. That’s it—width is identical, length is the only difference. Manufacturers allow tiny variances (think half an inch either way), so don’t panic if you see a spec sheet say 38.5 or 39 inches. If you searched for tempur pedic twin mattress dimensions, that 38 × 75 (or 38 × 80 for XL) is the baseline.

Thickness and why it matters more than you think

Tempur-Pedic twins typically run about 10 to 13 inches thick depending on the model—Cloud is often around 10 inches, Adapt about 11, ProAdapt 12, LuxeAdapt and LuxeBreeze closer to 13. That height affects two things right away: sheet pocket depth and how high the bed actually feels. Standard fitted sheets handle roughly 12–14 inches; deep-pocket sets are safer if your profile hits 13 inches or you add a topper. It sounds fussy, but waking up to a fitted sheet that pops off every night is, well, not the dream.

Frames, bases, and little fit quirks nobody mentions

Tempur-Pedic foam loves a solid, supportive base. A platform or slatted frame is great as long as slats are sturdy and no more than about 3 inches apart; otherwise, use a bunkie board or a compatible foundation. Adjustable bases are totally fine—and honestly a nice pairing with foam—just match the Twin or Twin XL size exactly. For bunk and loft beds, check guardrail height and the frame’s maximum mattress thickness: many specify 6–8 inches for the top bunk. Most Tempur-Pedic twins exceed that, so they’re usually not top-bunk friendly. One more real-world note: these mattresses are dense. A twin can weigh roughly 40–60 pounds, so measure hallways and turns before delivery day.

Sheets, protectors, and comforters that actually fit

Twin sheets are cut for 38 × 75; Twin XL sheets are cut for 38 × 80. Same width, different length, so XL sheets won’t tuck cleanly on a standard Twin and vice versa. If your Tempur-Pedic is 12–13 inches tall, aim for deep-pocket sheets and a stretch-knit mattress protector—the elastic matters more than the brand name here. Comforters and duvets are more forgiving; most Twin/Twin XL comforters drape fine over both, though XL-specific sets give nicer coverage on the longer bed. If you’re comparing sets based on tempur pedic twin mattress dimensions, prioritize pocket depth and elastic first, labels second.

Twin vs. Twin XL: who should pick what

If you’re under about 6 feet tall and tight on space, a standard Twin is perfect. Over 6 feet? Go Twin XL—those extra 5 inches save your ankles, and many dorms require Twin XL anyway. Same footprint width-wise, so the room layout barely changes, but the sleep comfort does. Believe it or not, that small length bump feels huge when you stretch out.

Weight and moving tips (so you don’t pull a muscle)

Tempur-Pedic foam is dense, which is why it feels so stable. The trade-off is heft. A Twin is manageable solo in short hops, but team-lifting is smarter for stairs. Don’t fold the mattress; a gentle bend is okay when moving around corners, and rotating it 180 degrees every so often helps wear. If it ships compressed, give it time—most models expand within hours, but full feel can take a couple of days. Worth the wait.

The quick cheat sheet, then what I’d do next

Here’s the gist: Twin is 38 × 75. Twin XL is 38 × 80. Most Tempur-Pedic twins sit around 10–13 inches tall, so deep-pocket sheets are your friend. Solid base, slats under 3 inches apart, and skip the top bunk.
