Sealy Posturepedic Plus RidgeCrest
7.4/10
- Strong edge support, 14-inch profile with ~1,072 coils
- High bounce (10 inches) good for combination sleepers and ease of movement
- No fiberglass in fire barrier, CertiPUR-US certified foams
- Competitive price for a full-size innerspring, available at Costco with generous return policy
- Mediocre pressure relief, foam layers feel basic under sustained pressure
- Slow foam recovery (2.8 seconds), can feel stuck if you change positions often
- Notable off-gassing on delivery, reviewers report 7-10 days to fade
- Moderate motion transfer, not ideal if a light-sleeping partner shares the bed
The RidgeCrest II is honest value for a traditional coil bed. The Costco return policy effectively gives you a 365-night trial. The weak point is comfort foam quality, which creates pressure buildup for side sleepers and lighter bodies under the hip and shoulder. Back and stomach sleepers in the 130-230 lb range will find it more serviceable.
Sealy Posturepedic Plus RidgeCrest: what you actually get
Sealy's Posturepedic Plus RidgeCrest is a Costco-exclusive. That matters, because the construction is simplified relative to Sealy's own direct-to-consumer Posturepedic Plus line, and the price reflects that. What you get for $849 queen is a 14-inch innerspring with a quilted comfort top, three polyfoam layers totaling 5 inches, and an 8-inch coil unit with roughly 1,072 coils and perimeter edge reinforcement.
The tall profile looks premium on paper. In practice, the foams above the coils are the weak link: lab testing puts pressure relief at the bottom third of innersprings tested, and the slow foam response (about 2.8 seconds full recovery versus the 0.4-second average) means the bed briefly holds a body impression when you shift positions. That is not a durability problem at this age, but it is worth knowing if you change positions overnight.
Edge support is a genuine strength. Sitting and lying at the perimeter both score well in testing, which matters for couples who use the full sleeping surface, or for anyone who sits on the edge to get dressed. The high coil bounce (10-inch rebound) also makes movement easy, a quality many people undervalue until they've slept on a slow-sinking foam bed for a few years.
Who the RidgeCrest suits, and who it doesn't
Good fit if you sleep on your back or stomach and weigh between 130 and 230 pounds, prefer a traditional bouncy innerspring feel over body-hugging foam, and want the lowest reasonable price for a full-profile coil mattress. The Costco return policy is a real safety net: the full-satisfaction return applies even to mattresses, effectively giving you close to a year to evaluate.
Not a great fit for side sleepers, who need deeper pressure relief at the hip and shoulder than the basic polyfoam layers provide. Also less suitable for heavier sleepers above 230 pounds, who will compress the foam layers quickly and feel the coils more directly. Combination sleepers may find the slow foam response disruptive when moving from side to back during the night.
If dedicated lumbar support is your priority for back pain, the RidgeCrest has Sealy's Targeted Support zone in the center third, but it is a basic zoning approach, not the same as the reinforced lumbar engineering found in purpose-built back-pain mattresses.

Comfort and firmness
The RidgeCrest ships in two versions: Medium (roughly 5 out of 10) and Firm (roughly 7 out of 10). The Medium version is more broadly appropriate, supporting back sleepers while allowing some contour at the shoulder. The Firm version skews toward stomach sleepers and heavier back sleepers who need the pelvis from sinking into any notable body-hug.
The quilted top cover adds a modest plush sensation on first contact, but this compresses quickly under body weight. The foams beneath are standard polyurethane, not gel memory foam or latex, and they behave accordingly: responsive but not particularly pressure-diffusing. Hot sleepers tend to run warm on this mattress because the comfort foam, while not thick, does trap some heat before the coil layer allows airflow below it.
Is it good for back pain?
Moderately useful for non-specific back pain in back sleepers. The coil unit provides a firm, relatively flat platform that keeps the lumbar in neutral alignment for most body weights in the 130-230 pound range. The Targeted Support zone adds some firmness under the lumbar, though reviewers note the effect is subtle compared to mattresses with dedicated lumbar reinforcement systems.
For side sleepers with hip or shoulder pain, the pressure relief deficit is a problem. The polyfoam layers do not diffuse hip-point pressure adequately for most side sleepers, particularly those above 150 pounds. A side sleeper on this mattress is more likely to wake with shoulder or hip discomfort than a back sleeper is.
A compatible adjustable bed base can help slightly, as elevating the legs reduces lumbar disc pressure. The RidgeCrest is adjustable-base compatible.
RidgeCrest versus online mattress alternatives
The RidgeCrest's most direct competitor is the Sweetnight innerspring line and similar entry-level coil hybrids.
If you value pressure relief as much as support, and are willing to spend a bit more, options like the with its zoned HIVE layer, or the Saatva Classic with its dual-coil construction and 365-night trial, will serve a wider range of sleep positions and body types better.
The Sealy Posturepedic Plus RidgeCrest is solid value for a traditional innerspring at around $849 queen via Costco. Strong edge support and high bounce are its real differentiators. The weak point is comfort foam quality, making it a poor fit for side sleepers or anyone prioritizing pressure relief.
Frequently asked questions
Is the Sealy Posturepedic Plus RidgeCrest a good mattress?
For back and stomach sleepers who want a traditional bouncy innerspring at a value price, yes. It performs acceptably in testing on edge support and bounce. The pressure relief is below average, which makes it a weaker choice for side sleepers or those with joint pain.
Where can I buy the Sealy RidgeCrest?
The RidgeCrest II "Plus" version is sold exclusively through Costco in the US. The original Ridgecrest is discontinued from Sealy's main lineup; some retailers may still carry old stock.
How long does a Sealy Posturepedic last?
Sealy offers a 10-year warranty on Posturepedic models, which aligns with the typical expected lifespan of 8-10 years for an innerspring at this price point. Heavier sleepers above 230 pounds tend to compress the comfort layers faster.
Is the RidgeCrest good for back pain?
Moderately useful for non-specific lower back pain in back sleepers. The Firm version keeps the spine in neutral alignment for most body weights. The Medium version is better for lighter back sleepers and side sleepers, though side sleepers will still find the pressure relief insufficient compared to a purpose-built back-pain mattress.
Does the RidgeCrest have fiberglass?
No. The RidgeCrest II uses a blended fiber batting as its fire barrier, not loose fiberglass. The foams are CertiPUR-US certified.
