Level Sleep TriSupport Mattress Reviews (2026)

The TriSupport's firm lumbar zone is its strongest feature. On my back, it held the middle of my body higher than a flat foam surface and prevented the hips from settling too deeply. It also kept partner movement remarkably quiet. The compromise is at the perimeter: lying near the edge felt secure enough, but sitting there caused a quick, obvious drop.

Because the mattress has been discontinued, it is not a practical new-bed recommendation. It remains a useful benchmark for sleepers who already own one or want to recreate its mix of targeted support, modest contouring, and strong motion isolation.

Who it suits

• Back sleepers who want firm support directly under the midsection
• Couples who prioritize motion isolation over edge strength
• Combination sleepers who want foam cushioning without a deep, slow sink

Who should skip it

• People who sit on the edge daily or sleep at the very edge
• Sleepers who find noticeable changes in firmness distracting
• Anyone who wants the bounce and airflow of a coil mattress

Over several weeks, we slept on the mattress on our backs and sides, changed positions repeatedly, evaluated support, and noted how well the foam relieved pressure at the shoulders and hips. Partner-movement drills showed how much vibration crossed the bed. We also tracked overnight warmth, timed how easily the surface recovered as we turned, and compared the center with the perimeter while both sitting and lying down. Our durability result is limited to short-term build stability; it is not a prediction of the mattress's full lifespan.

Our Testing Experience

The zoning was easy to feel on the roughly 10-inch sample. My shoulders settled first, followed by a firmer push under the lower back that stopped my hips from drifting downward. After a few nights, the transition felt natural while back sleeping. Side sleeping was less universal: landing in the softer shoulder area worked well, but moving too far up or down made the change in firmness more noticeable.

The foam was responsive enough that turning did not require much effort, yet it still absorbed movement effectively. During partner checks, routine position changes stayed on the other side instead of rippling across the surface. Marcus, who is 6'1" and about 230 pounds, also felt steady through the lumbar area. He noticed more warmth during long periods without movement, which matches the mattress's average cooling performance.

The perimeter produced the clearest weakness. We could lie close to it without feeling as if we would roll off, but sitting in the same area compressed the foam quickly. That difference matters for anyone who uses the edge to get dressed, tie shoes, or push up from the bed.

What we liked

• The lumbar zone kept the midsection level without making the entire bed feel hard
• Partner movement stayed localized, even during repeated turns
• The surface recovered quickly enough for comfortable position changes

Who it is best for

• Back sleepers whose hips tend to sink too far into uniform foam
• Back-to-side combination sleepers who line up with the softer shoulder zone
• Couples who value a calm surface more than a firm perimeter

Where it falls short

• The edge compresses too much for frequent sitting
• The foam can retain warmth during long, still stretches
• The firmness transitions may feel awkward if your body does not align with the zones

• Type: all-foam mattress with zoned polyfoam support
• Height: approximately 10 inches for the reviewed sample; archived specifications vary by production version
• Construction: zoned comfort foam over a polyfoam support core
• Feel: medium overall, with much softer cushioning near the shoulders and firmer support through the lumbar area
• Cover: soft, four-way-stretch polyester
• Availability: discontinued under the Level Sleep brand; it was originally shipped compressed

Use the TriSupport as a reference point rather than a product to hunt down. Its closest match is not simply any medium foam mattress; look for a bed that combines softer shoulder cushioning with firmer support under the waist. Back sleepers and combination sleepers are the most likely to benefit from that layout.

For a current all-foam option with deeper contouring, the Nectar Premier Memory Foam is the more natural place to start. The WinkBed Luxury Firm is a better direction if airflow, bounce, and edge support matter more. The Saatva Classic pushes the feel further toward a traditional innerspring, while the TEMPUR-Cloud Medium favors slow, close contouring and low motion transfer.

Comfort depends heavily on where your shoulders, waist, and hips land. Taller or shorter sleepers may not line up with the zones in the same way, and frequent position changes can make the transitions more obvious. Body weight changes the feel as well: a heavier sleeper presses farther into each section and is more likely to notice the softer perimeter. The mattress also lacks the airflow and reinforced edge found in many hybrids.

Archived specifications do not describe every production version in exactly the same way, so owners comparing replacement mattresses should focus on feel and zoning rather than trying to match a layer diagram precisely.

Nectar Premier Memory Foam: This is the closest option in price and construction to the TriSupport's former position in the market. Its thicker memory-foam comfort system creates a deeper, more even cradle, which can feel better at the shoulders for side sleepers. It does not reproduce the Level's sharply defined lumbar zone.

WinkBed Luxury Firm: The WinkBed pairs a cushioned Euro top with zoned coils and reinforced edges. It feels livelier, sleeps cooler, and is far more stable for sitting at the side. The TriSupport isolates movement more thoroughly and feels less springy, while the WinkBed belongs to a higher current price tier.

Saatva Classic: The Saatva Classic uses a dual-coil design, a Euro pillow top, and firmer support through the center third. It is easier to move on and offers a much sturdier perimeter, but its motion is more noticeable than on the Level's foam surface. Multiple firmness and height choices also make it easier to tailor than the discontinued TriSupport.

TEMPUR-Cloud Medium: At roughly the same height as the reviewed Level sample, the TEMPUR-Cloud offers deeper, slower contouring and excellent motion control. Choose it for body-hugging pressure relief, not for an obvious lumbar lift. It also sits in a higher price tier than the Level's former list price.

• Give a compressed foam mattress time to expand before judging its support.
• Use breathable sheets and a light protector if you tend to sleep warm.
• Back-to-side sleepers should position the shoulders over the softer zone.
• Rotate the mattress periodically so the comfort layers wear more evenly.
• If the firmness transitions feel too abrupt, a thin topper can soften them without completely hiding the lumbar support.

Yes. The firmer support under the lower back was easy to notice, especially while lying on the back. It kept the hips from settling as deeply as they did on a uniform foam surface.

It is a strong choice for light sleepers who wake when a partner turns. Routine movement remained localized, though couples who use the full width of the bed may find the soft perimeter limiting.

No. The edge is usable for brief sitting, but it compresses too quickly for anyone who depends on a firm side when dressing or getting out of bed.

Yes for an all-foam mattress. The surface recovered without a long delay, so turning felt manageable, but it did not have the lift or bounce of an innerspring bed.
