Therapedic Mattress Reviews (2026)

Agility is the better fit for most shoppers. Its 11-inch build feels buoyant and easy to move across, but it still cushions the shoulders and hips well. Choose it if you change positions often or want a hybrid that feels softer and less rigid than Terracotta. Light sleepers who share a bed should expect some movement to travel across the microcoil layer, and frequent edge sitters may want a firmer perimeter.

Immunity Terracotta is worth the upgrade when cooling and edge stability matter more than price. The 14-inch latex-and-coil design stays lifted, rebounds almost immediately, and remains composed near the sides. It is the stronger choice for hot sleepers, couples who spread out, and anyone who sits on the edge while getting dressed. Skip it if you want a deep memory-foam hug or need a mattress that is easy to carry upstairs.

We used the same bedroom, foundation, protector, and room-temperature range for both mattresses. Each went through repeated overnight sessions with testers between 150 and 210 pounds who rotated among side, back, and stomach positions. Along with full nights of sleep, our evaluation process included measured sink, surface-temperature checks, timed rebound, partner-movement observations, and equal-load comparisons at the center and edge. We also checked the mattresses again after repeated rolling and position changes to see whether their feel or height shifted.

Our Testing Experience

Agility felt easy to move on from the first night. Our sample measured 11.0 inches high and landed at 5.5 out of 10 on our firmness scale: soft enough to ease pressure at the shoulder, but buoyant enough to keep the hips from settling too far. The surface recovered 90% of its height in 1.3 seconds after the load was removed, which matched the quick feel we noticed when turning from side to back. After 30 minutes of lying still, the surface temperature rose 4.2°F—comfortable for a hybrid, though not as cool as Terracotta. With the same 50-pound load, the edge compressed 2.1 inches versus 1.8 inches at the center. It remained usable near the side, but sitting there felt softer than lying there.

• What we liked:

  • Fast rebound makes position changes feel effortless.

  • The softer surface cushions joints without letting the midsection sag.

  • Heat buildup stays moderate for a foam-and-latex hybrid.

• Who it is best for:

  • Combination sleepers who turn several times a night.

  • Side sleepers who want contouring without a deep foam hug.

  • Shoppers who want a responsive hybrid at a lower price than Terracotta.

• Where it falls short:

  • Large turns are more noticeable across the bed than on dense foam.

  • The brand does not publish a standard firmness rating.

  • The perimeter dips more while sitting than Terracotta's reinforced edge.

Our Testing Experience

Terracotta felt more structured the moment we lay down. The sample measured 14.0 inches high and registered 6 out of 10 for firmness, with a smooth surface that held the body higher than Agility. It recovered 90% of its height in 0.8 seconds, so turning never required pushing against a deep impression. The surface gained only 3.1°F after 30 minutes, the smallest increase of the two mattresses. Its edge was equally convincing: a 50-pound load compressed the perimeter 1.5 inches and the center 1.7 inches. That small difference matched the steady feel we noticed when lying or sitting close to the side. The main drawback was practical rather than physical—the Queen weighs 124 pounds, so setup takes two people.

• What we liked:

  • The surface held the least heat during the 30-minute test.

  • Full-perimeter reinforcement kept the sides close to center firmness.

  • Latex and coils produced fast, controlled rebound without a sharp bounce.

• Who it is best for:

  • Hot sleepers who want a cool-to-the-touch cover and open coil core.

  • Couples who need reliable support across the full width of the bed.

  • Back and combination sleepers who prefer medium-firm lift.

• Where it falls short:

  • The price is substantially higher than Agility and many online hybrids.

  • The 124-pound Queen is difficult to move without help.

  • The lifted feel will disappoint shoppers who want a slow, deep foam hug.

Performance Scores

Start with how much surface give you want. Agility's 5.5-out-of-10 test feel lets the shoulder and hip settle more easily, so it works better for side and combination sleepers. Terracotta's 6-out-of-10 feel keeps the body higher and gives the perimeter more authority, making it the better match for back sleepers, couples who use the entire bed, and anyone who sits near the edge. Hot sleepers also gain more from Terracotta's copper cover and open latex-and-coil build. Price is the clear dividing line: Agility costs far less, while Terracotta pays back the upgrade through cooling, edge stability, and a longer warranty.

• Choose Agility for easier pressure relief, frequent position changes, and better value.

• Choose Terracotta for cooler sleep, stronger edges, and medium-firm lift.

• Check current size availability before ordering; heavy Terracotta sizes may be retailer-only.

Agility vs. Leesa Original Hybrid: Both are 11-inch hybrids with comparable Queen list prices. Leesa uses memory foam and full-size pocketed springs, giving it more of a foam hug and a medium-to-medium-firm feel. It also offers a 120-night trial and limited lifetime warranty. Agility feels lighter and quicker because its comfort system combines latex with mini microcoils. Choose Leesa if you want deeper contouring and longer policy coverage; choose Agility if easy movement and a less foam-heavy surface matter more.

Immunity Terracotta vs. Saatva Latex Hybrid: These mattresses occupy a similar premium price tier and both use natural latex over individually wrapped coils. Saatva is 12 inches high, rated medium firm, and adds five-zone lumbar support, a 365-night trial, lifetime warranty, in-room setup, and old-mattress removal. Terracotta is two inches taller and uses a cooling copper cover with strong full-perimeter support. Saatva offers the more complete service package; Terracotta is the more distinctive choice for a cool surface and a substantial, edge-secure feel.

• Use the brand's 30-night adjustment period before deciding on a return. Both hybrids soften slightly as the cover and comfort layers settle.

• Pair the mattress with breathable sheets and a low-bulk protector. Thick, tightly woven bedding can blunt the feel of a cooling cover.

• Plan setup before delivery. Agility works on a firm, flat surface, while Terracotta's 124-pound Queen is much easier to place with a second person.

Immunity Terracotta stayed cooler. Its surface temperature rose 3.1°F after 30 minutes, compared with 4.2°F on Agility. Both slept comfortably for hybrids, but Terracotta's copper cover, latex, and open coil core released heat more effectively.

Agility is the better starting point for most side sleepers because its softer test feel lets the shoulder and hip settle more easily. Terracotta still relieves pressure well, but its medium-firm, lifted surface suits side sleepers who prefer less sink.

Terracotta is the stronger all-around choice for couples because its reinforced perimeter keeps more of the surface usable. Agility absorbs small movements well, but large turns are slightly easier to notice across the bed.

Agility felt easiest for repeated position changes and earned the higher responsiveness score at 4.6 out of 5. Terracotta rebounded faster in the load test, but its firmer, heavier surface felt more substantial under the body.
