In the US, "super single" usually means a three-quarter (48 x 75) mattress — a custom size most mainstream brands don't make. Here are the SERP-consensus US makers that do, plus sizing, sheets, and what to know before you buy.
If you've been searching for a best super single mattress list and only finding generic queen and full picks, here's why: in the US, "super single" usually means a three-quarter (3/4) mattress at 48 inches wide by 75 inches long — a legacy / specialty size that mainstream brands like Saatva, Helix, Tempur-Pedic, and Layla don't manufacture. The size shows up most often in RVs, antique beds, bunk rooms, and small guest spaces.
We rebuilt this guide from scratch in 2026 because the previous version recommended brands that don't actually offer this dimension. This one points you at the US makers that do — sourced from the live Google SERP for "super single mattress 48 x 75" — plus the sizing, sheet, and trial-window details you'll need before you buy.

The term is regional. In Singapore and parts of the UK, "super single" is a standard retail size around 42–48 inches wide. In the US, no major mattress retailer uses "super single" as a stocked size — what shoppers usually mean is the three-quarter size: 48 inches wide by 75 inches long, 10 inches wider than a Twin and 6 inches narrower than a Full.
One outlier worth flagging: Original Mattress Factory uses "Super Single" for their proprietary 46.5 by 81 inch size. If you're buying from them, confirm the dimensions before ordering — it isn't the same bed as a three-quarter.
According to a 2026 SERP People Also Ask answer, three-quarter mattresses "are considered a thing of the past" as a standard mass-market size, which is why the brands in this guide are specialty / RV / custom shops rather than the household sleep brands you'll see on TV.
If your situation is unusual (an antique three-quarter bed, a sleeper-cab cutout, an RV bunk with a contoured corner), expect to call. These are small-batch builders. Half of them will ship inside a week; the other half will ask for a template.
The Luxury Adventure Hybrid is the closest thing to a "premium mainstream hybrid" you can get in the 48 x 75 size. Encased coils with cooling-gel foam, a 20-year warranty, and a 120-night trial — feature parity with what national brands offer in queen/king, just in a size most national brands skip.
Currently listed around $919 (sale price; MSRP $1,620). Free FedEx shipping in the contiguous US.
Brooklyn Bedding doesn't list a 48 x 75 in its main lineup — but its RV-focused short full at 48 x 74 is a one-inch-shorter cousin that fits most three-quarter frames and antique beds with a slim mattress pad to take up the slack. The Signature Hybrid in this size starts around $719 (currently 25% off MSRP $959) with a 120-night trial.
If you want a name brand with a real customer-service operation behind your purchase, this is the one. Verify your frame's interior dimensions before ordering — the 1-inch length difference matters for bunks but is negligible for most freestanding three-quarter beds.
Mattress Insider also stocks an 8.5" natural-latex build in 48 x 75 with an organic cotton cover — around $579 sale ($849 MSRP). Latex runs cooler than memory foam, which matters in a bunk or antique-bed footprint where airflow underneath is limited. Mattress Insider rates this model as eco-friendly with a long durability profile, and ships free in the contiguous US.
If you'd rather get a fully customizable Dunlop latex stack and don't mind a longer lead time, CustomMattress.com builds three-quarter latex to spec — you'll need to call for an exact quote.
Best for buyers who want to dial in firmness. Magic Sleeper's 12" Refresh Hybrid offers five firmness levels — Extra Soft through Extra Firm — in three-quarter, starting around $460. Their lineup also includes a budget 5" all-foam build at $179 and a Brooklyn Bedding Dreamfoam variant at $205, which is useful if you're outfitting a bunk room with multiple beds at different price points.
Trade-off: 100-night trial vs. the 120 days you get from larger competitors. Worth it for the firmness range — there's no other shop in this size offering five distinct comfort levels.
If the bed is for a guest room you use twice a year, an antique three-quarter you're trying to keep period-correct, or a kid's bunk where you're going to replace the mattress in a few years anyway, Mattress Insider's Sedona — listed around $293 — is the cheapest legitimate three-quarter you can buy from a US specialist. Innerspring construction, firm feel, ships free.
Don't expect cooling tech or a contoured comfort layer at this price. It's a basic, durable, period-appropriate bed.
Three-quarter sheets exist but aren't sold at department stores. The reliable channels are RV-bedding shops and Amazon listings tagged "3/4" or "48 x 75" — Aanya Linen, Walmart's RV-camper line, and ABORN are the most consistent stockers. Order sheets when you order the mattress so you're not sleeping on whatever's in the closet for two weeks.
Antique three-quarter beds drift. The label or family memory may say "three-quarter" but the rails could measure 47.5 x 74 or 48.5 x 76. Tape-measure the interior and order to that, allowing 1/2" of clearance. A too-tight mattress fights the frame for years; a too-loose one leaves a sheet-snagging gap.
Bunks and antique three-quarter frames often have less than 10 inches of vertical clearance. If you've got a low loft or a guard rail height to clear, opt for the 7"–8.5" builds (Sedona, the Latex RV, the 8" Gel Memory Foam) over the 12" Refresh or 14" hybrid options.
Specialty shops honor trial windows, but most charge return freight on a custom-size return. Read the trial fine print before you order, and try the mattress for at least 14 nights — these aren't memory-foam cloud builds you'll "feel out" on night one.
In US shopping language, yes — most people searching for a "super single mattress" mean the three-quarter (3/4) size, 48 inches wide by 75 inches long. The exception is Original Mattress Factory, which uses "Super Single" for their proprietary 46.5 x 81 size. Confirm dimensions with whichever retailer you're buying from before ordering.
Three-quarter mattresses haven't been a mass-market size in the US since roughly the 1950s. Mainstream sleep brands optimize their factories around twin / twin XL / full / queen / king. Specialty RV and custom-build shops fill the 48 x 75 demand because those buyers (RV owners, antique-bed owners, bunk-room buyers) are willing to pay for a non-standard build.
No. Twin sheets (39 x 75) are 9 inches too narrow; Full sheets (54 x 75) are 6 inches too wide and will bunch under the corners. You need three-quarter / 48 x 75 sheets specifically — sold by RV bedding specialists and on Amazon under '3/4 mattress sheets' or '48 x 75 sheet set.'
Often yes — "three-quarter" is one of the standard RV bunk sizes. Some RVs use 48 x 74 (short full) or 48 x 80, so always measure your bunk's interior before ordering. Brooklyn Bedding's RV line, Mattress Insider, and Magic Sleeper all build for RV bunks specifically and will let you confirm fit before you buy.
Budget innerspring builds start around $290 (Mattress Insider Sedona). Mid-range gel memory foam runs $400–$600. Latex and entry hybrids fall in the $500–$750 range. Premium hybrids with mainstream-brand feel and 20-year warranties top out around $900–$1,000. Anything materially above $1,500 should give you full custom build options (Naturepedic / SleepEZ / true custom Dunlop).
Not comfortably. At 48 inches wide it gives each sleeper roughly 24 inches — about the width of a crib mattress per person. It works for one adult plus a small child, or two slim adults short-term, but a Full (54") or Queen (60") is meaningfully more comfortable for couples.
