Orthos Ultra Plush Mattress Reviews (2026)

Yes—if you want a soft mattress that still feels distinctly springy. The top cushions the shoulders and hips, while the offset-coil unit keeps the bed responsive and supports the midsection. Its edge is also firmer than the center, so more of the mattress feels usable. Flipping and rotating spreads wear across both sides, although that maintenance takes more effort than rotating a one-sided bed.

The connected-coil design is the deciding trade-off. A partner’s turns and trips out of bed are easier to feel than on many pocketed-coil hybrids. This is a strong choice for solo sleepers and partners who are not easily disturbed, but couples sensitive to movement should look elsewhere.

• Who it suits

  • Side sleepers and back/side combination sleepers who want cushioning without a slow foam hug

  • People who sit on the edge or use the full width of the bed

  • Owners willing to flip and rotate a heavy, two-sided mattress

• Who should skip it

  • Light sleepers who wake when a partner changes position

  • Dedicated stomach sleepers who need a flatter, firmer surface

  • Anyone looking for the close contouring and muted response of memory foam

We used the mattress over multiple nights and repeated the checks after the comfort layers had settled. The overall method followed our mattress testing process. Support covered spinal position and midsection stability; cooling tracked surface heat after 30 minutes; and pressure relief focused on the shoulders and hips during side sleeping. We also measured motion isolation, responsiveness, and edge support with repeatable weight, movement, and compression checks.

Our Testing Experience

Our sample measured 14.2 inches high and felt like a 4 out of 10 for firmness, with 10 being the firmest. Side sleeping produced about 2.0 inches of shoulder sink and 1.7 inches at the hip, enough to soften those pressure points without leaving the waist unsupported. The offset coils rebounded as soon as we turned, so the mattress felt buoyant rather than slow or enveloping.

Heat control was good for such a plush bed. The surface warmed 5.2°F after 30 minutes and returned to within 1.5°F of its starting temperature 10 minutes after we got up. The motion test exposed the main weakness: a 10-pound ball dropped from 6 inches produced an average 0.22 g peak at a sensor 24 inches away, and noticeable vibration lasted about 1.4 seconds. Those results matched the movement we felt when another person rolled over.

The perimeter performed much better. A 150-pound load placed 2 inches from the edge compressed the mattress 2.8 inches, compared with 2.3 inches at the center. That small difference kept the edge from feeling as though it would slide away while we sat down, and lying near the side still felt secure.

What we liked

• Deep surface cushioning with firm, immediate support underneath

• A stable perimeter that remains useful for sitting and near-edge sleep

• Quick, spring-driven movement with no stuck feeling

Who it is best for

• Side sleepers and back/side combination sleepers who prefer a soft surface

• People who rely on the edge when getting into or out of bed

• Shoppers who value a flippable design and will keep up with the maintenance

Where it falls short

• Partner movement travels clearly through the connected coil unit

• The hip area can sink too deeply for dedicated stomach sleepers

• Flipping a 14.25-inch mattress takes more effort than rotating a one-sided model

• Type: Two-sided innerspring mattress

• Height: 14.25 inches

• Feel: Soft

• Quilt: Woven damask over natural wool and 1 inch of foam

• Comfort layers: Two 1-inch layers of high-density Supersoft foam and a heavyweight stitched cotton pad

• Foam: Approximately 3 inches of CertiPUR-US-certified foam per side, including the quilt foam

• Support core: Six-turn, 12.75-gauge knotted offset coils; 400 coils in the full size; 6-gauge border rod

• Edge reinforcement: Cylinder supports in every other perimeter coil

• Listed prices at the time of review: Twin $759; Twin XL $789; Full $1,029; Full XL $1,069; Queen $1,199; King $1,529; California King $1,569

• Comfort and size changes: One reselection within 365 days; a 25% fee applies to the lower-priced piece, and price differences plus delivery or pick-up fees may apply

• Returns: OMF does not accept standard mattress returns; the original mattress must be surrendered or donated when using the reselection policy

• Warranty: 12-year limited warranty covering qualifying defects, not ordinary changes in comfort or support

Choose the Orthōs Ultra Plush if you want a soft first impression, quick spring response, and a perimeter that stays useful. It is best suited to side sleepers and back/side combination sleepers who enjoy cushioning but dislike sinking slowly into foam. It also makes sense if a two-sided design matters enough that you are willing to flip a substantial mattress every few months.

Look elsewhere if you spend the whole night on your stomach, share the bed with a light sleeper, or cannot comfortably flip a thick mattress. Saatva Classic offers more firmness choices and a different service package, while Beautyrest Black and Stearns & Foster Lux Estate use more modern coil-and-foam constructions. All three alternatives generally cost more.

The soft upholstery can allow a stomach sleeper's hips to settle too deeply, and the connected offset coils pass movement from one side to the other. The mattress also asks more of its owner: regular flipping and rotating are central to sharing wear across both surfaces. Finally, OMF's policy is a fee-based reselection rather than a standard refund, so the in-store comfort decision matters.

• Saatva Classic is the closest match for a buoyant innerspring feel, but it adds three firmness choices, two height options, a dual-coil design, and an in-home trial with setup. Its Plush Soft version is the most relevant comparison. Choose Saatva for flexibility and service; choose the Orthōs for a lower price and a genuinely two-sided build.

• Beautyrest Black is a collection rather than one mattress. Current models use pocketed coils and more foam, which makes them the better direction for shoppers who place motion separation above easy flipping. The exact feel and price depend on the series, and even entry models usually sit above the Orthōs Ultra Plush in price.

• Stearns & Foster Lux Estate combines IntelliCoil springs with TEMPUR-Indulge memory foam and comes in several feels and top styles. It offers a denser, more polished luxury experience, but it costs substantially more and does not provide the same straightforward two-sided construction.

• Allow at least a 30-night adjustment period before using OMF's comfort-reselection policy.

• Flip and rotate monthly during the first few months, then about every three months to share wear across both sides.

• Use a breathable, washable protector to guard the cover against moisture and stains.

• If you mostly sleep on your stomach, use a thinner pillow and check whether your hips remain level rather than trying to correct a poor fit with posture alone.

• Use an adequate center support on full, queen, and king sizes so the frame does not create sagging or compromise warranty coverage.

• If the surface is already too soft, do not add a thick plush topper; choose a firmer mattress instead.
