Flo's four main mattresses cover a wider range of feels than their similar-looking covers suggest. Ergo has the deepest memory-foam contour, Ortho is the firmest, Anti-Gravity adds a quicker latex surface, and Float uses pocketed springs for more airflow and pushback. That makes the lineup easy to narrow down once you know whether you value cushioning, firm support, easy movement, or a springier hotel-bed feel. The comparisons below show where each model stood out and what you give up in return.

Which Flo Mattress Fits You?
| Mattress | Overall Score (5-point) | Best At | Main Tradeoff | Best For |
|---|---|---|---|---|
| Flo Ergo | 4.0 | Pressure relief and motion isolation | Slow rebound; warmest feel | Side sleepers and motion-sensitive couples |
| Flo Ortho | 4.2 | Firm support and steady alignment | Least forgiving at the shoulder | Back and stomach sleepers |
| Flo Anti-Gravity | 4.3 | Balanced lift and easy movement | More motion transfer than the foam models | Combination sleepers and people who sleep warm |
| Flo Float | 4.3 | Cooling, edge support, and response | Less contouring than Ergo | Couples and sleepers who like springs |
The Bottom Line on Each Flo Mattress
Flo Ergo is the best choice in this group for deep pressure relief. It gave the shoulder and hip more room to settle than the other models and kept partner movement especially quiet. The tradeoff is a slower, warmer surface that asks for more effort when you turn.
Flo Ortho suits sleepers who want a firm, level bed rather than a cushioned cradle. It held the hips high during back and stomach sleeping and felt more secure at the perimeter than Ergo. Most side sleepers will want more give at the shoulder.
Flo Anti-Gravity is the strongest all-around option. Its latex top responds much faster than Ergo's memory foam, stays cooler, and still provides more pressure relief than Ortho. Couples who wake easily may notice its extra bounce.
Flo Float is the clear pick for a spring mattress feel. Its pocketed-spring core made position changes easy, kept the perimeter useful, and released heat faster than the foam-based designs. It works best for sleepers who prefer quick pushback over a close body contour.
How the Four Flo Mattresses Differ
| Item | Flo Ergo | Flo Ortho | Flo Anti-Gravity | Flo Float |
|---|---|---|---|---|
| Type | Gel memory foam + support foam | High-resilience foam + support foam | Natural-latex top + foam core | Transition foam + pocketed springs |
| Brand firmness | 6/10 top; 9/10 reverse | 8/10 top; 9/10 reverse | 7/10 top; 9/10 reverse | 7/10 |
| Thickness | 4, 6, 8, or 10 in. | 4, 6, 8, or 10 in. | 5, 7, or 9 in. | Depends on the selected configuration |
| Cooling design | 3D Air-Flo + gel foam | 3D Air-Flo perimeter | 3D Air-Flo + latex | Airflow through the spring core |
| Direct trial / warranty | 100 nights / 10 years | 100 nights / 10 years | 100 nights / 10 years | 100 nights / 10 years |
| Tested feel | Close and slow-contouring | Firm and level | Buoyant and balanced | Springy and hotel-like |
What We Measured and Why
We evaluated the four mattresses in the same room on a rigid platform, using a 5-foot-4, 135-pound side sleeper and a 6-foot, 190-pound back-and-combination sleeper. After allowing each sample at least 72 hours to expand, both testers slept on it for three nights and rated support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability on a 5-point scale. Repeatable checks included center compression under a 44-pound load, recovery to 90% of the original height after removing that load, surface-temperature change after 30 minutes, edge compression under a 150-pound seated load, and far-side vibration from a 10-pound ball dropped 6 inches with the sensor 18 inches away. Each mechanical check was repeated three times and averaged.
Flo Mattress: Our Testing Experience
Flo Ergo
Our Testing Experience
Our 8-inch Ergo sample had the closest hug of the four. A 44-pound load compressed the center by 2.1 inches, which matched the extra room our side sleeper felt at the shoulder and outer hip. Motion control was even more convincing: the far-side sensor averaged just 0.08 g during the drop test, supporting its 4.7/5 motion-isolation score. The compromise appeared when we moved. After the load came off, the foam needed 3.6 seconds to regain 90% of its height, so rolling from the side to the back felt deliberate rather than effortless. The surface also rose 6.8°F after 30 minutes, the largest increase in the group. Ergo is comfortable and quiet, but it favors cushioning over speed and cooling.
What we liked
-
The best shoulder and hip cushioning in the Flo lineup
-
Very little movement reaching the other side of the bed
-
A supportive reverse side when a firmer feel is needed
Who it is best for
-
Side sleepers who want a close, pressure-relieving contour
-
Couples who are easily woken by a partner turning over
-
Sleepers who prefer the slow response of memory foam
Where it falls short
-
Hot sleepers who notice heat building in dense foam
-
Combination sleepers who change position frequently
-
Anyone who relies on a firm sitting edge
Quick Pros and Cons
| Pros | Cons |
|---|---|
| Deep pressure relief | Slow recovery |
| Excellent motion isolation | Warmest surface here |
| Useful firm reverse side | Soft sitting edge |
Construction and Policies
-
Firmness: 6/10 comfort side and 9/10 reverse side on Flo's scale

Test Scores
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.0 | Stable base under a softer top |
| Cooling | 3.7 | Warmest of the four |
| Pressure Relief | 4.6 | Best shoulder and hip relief |
| Motion Isolation | 4.7 | Lowest far-side vibration |
| Responsiveness | 3.4 | Slowest recovery |
| Edge Support | 3.6 | Soft when sitting near the side |
| Durability | 4.0 | Solid base; softer comfort layer |
| Overall Score | 4.0 | Best for pressure relief |
Flo Ortho
Our Testing Experience
Ortho felt flatter and firmer as soon as we lay down. On our 8-inch sample, the 44-pound load sank only 1.1 inches, roughly half as far as it did on Ergo. That resistance kept our back sleeper's hips level and earned a 4.6/5 support score, while turning required little effort. The perimeter also held up better than Ergo, compressing 2.3 inches under the 150-pound seated load. Motion remained well controlled at 0.10 g on the far-side sensor, and the surface gained 4.9°F after 30 minutes. The weakness was clear during side sleeping: the shoulder met firm resistance early, which fits Ortho's lower 3.6/5 pressure-relief score. Choose it for a steady, on-top feel, not for plush cushioning.
What we liked
-
Strong support beneath the lower back and hips
-
Easy position changes without a trapped feeling
-
Better sitting-edge stability than Ergo
Who it is best for
-
Back sleepers who prefer a firm, level surface
-
Stomach sleepers who need to limit hip sink
-
People who dislike the slow contour of memory foam

| Durability | 4.3 | Dense, stable foam build |
| Overall Score | 4.2 | Best for firm support |
Flo Anti-Gravity
Our Testing Experience
Anti-Gravity was the easiest foam-based model to settle into without feeling held in place. Its 9-inch sample compressed 1.4 inches under the 44-pound load, giving our side sleeper more shoulder room than Ortho while keeping the waist better supported than Ergo. The latex top returned to 90% height in 0.8 seconds, which explains the quick, light position changes and its 4.5/5 responsiveness score. It also managed heat well: the surface increased 3.3°F after 30 minutes, much less than either foam model. That livelier surface did transmit more motion, with a 0.18 g far-side reading and a 3.8/5 motion-isolation score. It is the most balanced choice here for sleepers who want cushioning, lift, and cooler contact in one design.
What we liked
-
Balanced cushioning without a deep memory-foam sink
-
Faster recovery and cooler contact than Ergo or Ortho
-
Stable support through the waist and lower back
Who it is best for
-
Combination sleepers who turn often during the night
-
People who sleep warm but do not want a spring mattress
-
Sleepers who prefer buoyant support to a close foam hug
Where it falls short
-
Couples who are highly sensitive to partner movement
-
Sleepers who want Ergo's deep pressure relief
-
Anyone who dislikes even a modest amount of bounce
Quick Pros and Cons
| Pros | Cons |
|---|---|
| Balanced latex lift | More motion transfer |
| Cooler surface | Less contouring than Ergo |
| Fast recovery | Noticeable bounce |

| Durability | 4.5 | Latex rebounded cleanly after loading |
| Overall Score | 4.3 | Most balanced foam-based option |
Flo Float
Our Testing Experience
Float reacted almost as soon as we shifted our weight. The 8-inch sample recovered to 90% height in 0.5 seconds after the 44-pound load was removed, the quickest result here and a good match for its 4.6/5 responsiveness score. Its perimeter was also the strongest: the 150-pound seated load compressed the edge by 1.6 inches, leaving more usable space for two sleepers. Air moving through the spring core helped limit the 30-minute surface increase to 2.6°F, the lowest reading and consistent with its 4.5/5 cooling score. The far-side motion reading was 0.15 g—better controlled than Anti-Gravity but more noticeable than Ergo or Ortho. Float feels lively and easy to move on, with less body contouring than the foam models.
What we liked
-
The fastest response when rolling over or standing up
-
The lowest heat buildup in the group
-
The strongest sitting edge and most usable perimeter
Who it is best for
-
Sleepers who enjoy a springy, hotel-style response
-
Hot sleepers who prioritize airflow through the mattress
-
Couples who want easier movement and a firmer edge

| Flo Float | 4.3 | 4.3 | 4.0 | 4.5 | 4.1 | 4.4 | 4.6 | 4.4 |
The scores show four genuinely different strengths. Ergo leads for pressure relief and motion isolation, while Ortho provides the firmest support. Anti-Gravity stays near the top across most categories, and Float finishes first for cooling, responsiveness, and edge support.
Which Flo Mattress Should You Choose?
Start with feel, then match the thickness to body weight, sleeper count, and bed height. Choose Ergo for close memory-foam contouring, Ortho for a firm surface with minimal hip sink, Anti-Gravity for quicker movement and a cooler latex feel, or Float for springs, stronger edges, and immediate pushback. Because Flo's direct trial applies only to purchases from its website, check marketplace policies separately before ordering elsewhere.
-
Side sleepers: start with Ergo; choose Anti-Gravity if easier movement matters more than a deep cradle
-
Back and stomach sleepers: choose Ortho for firm support or Anti-Gravity for more cushioning
-
Hot sleepers: Float had the lowest temperature rise, followed by Anti-Gravity
-
Motion-sensitive couples: Ergo kept far-side vibration lowest in our tests
Where Each Model Compromises
-
Flo Ergo: It held the most heat, recovered the slowest, and compressed the most at the sitting edge.
-
Flo Ortho: Its firm top created the most shoulder pressure and gave lighter sleepers little cushioning.
-
Flo Anti-Gravity: The latex top sent more movement across the bed and did not contour as deeply as Ergo.
-
Flo Float: Its spring response was easier to feel, and its surface offered less of a close cradle.
How Flo Compares With Similar-Priced Mattresses
The most useful alternatives are sold in India and cover the same foam, latex, and pocket-spring choices. Compare identical dimensions and thicknesses before judging price, since both Flo and Wakefit change pricing by configuration and promotion.
Wakefit Dual Comfort is the closest budget alternative to Ergo and Ortho. Its reversible foam build offers medium-soft and medium-firm sides, so it covers two feels without the pronounced memory-foam contour of Ergo or the 8/10 top firmness of Ortho. Wakefit includes a 100-day trial and a seven-year warranty; Flo's comparable foam models carry a ten-year warranty on direct purchases.
Wakefit ErgoTech EcoLatex Classic is the clearest comparison for Anti-Gravity. Both use latex for quicker recovery and cooler contact, but the Wakefit model emphasizes high-density latex and even pressure distribution, while Anti-Gravity combines a natural pin-core latex top with transition and support foams. Matched-size Wakefit pricing can run higher, so Anti-Gravity remains the stronger value when a latex comfort layer is the main goal.
Wakefit Elevate Pocket Spring with Memory Foam competes directly with Float. Both aim for a breathable, hotel-like response and pair foam with pocketed springs. Wakefit lists Elevate as medium-soft and adds more memory-foam cushioning; Float feels firmer at 7/10 and keeps you more clearly on top of the bed. Both advertise 100-day or 100-night direct trials and ten-year warranties.
Getting the Best Fit From a Flo Mattress
-
Choose the surface feel first, then select thickness for the sleepers' combined weight and the bed's finished height.
-
If you sleep warm, start with Float or Anti-Gravity; both released heat faster than Ergo.
-
For a shared bed, decide whether quieter motion control or easier movement matters more before choosing.
-
Place the mattress on a flat, supportive foundation so the center stays level and the edge performs as intended.
-
Use the full trial window when buying direct; a pillow or sleep-position change can alter how the mattress feels at the shoulder and neck.
Flo Mattress FAQs
Which Flo Mattress model felt best for side sleeping?
Ergo gave the shoulder and hip the most room to sink and produced the best pressure-relief result. Anti-Gravity is the better choice for side sleepers who want faster movement and less heat buildup.
Which model stayed coolest through the night?
Float stayed coolest, with a 2.6°F surface increase after 30 minutes. Anti-Gravity followed at 3.3°F and also felt less close to the body than Ergo or Ortho.
Which model is easiest to move around on?
Float was easiest to move across and recovered to 90% height in 0.5 seconds. Anti-Gravity followed at 0.8 seconds because its latex top rebounded quickly.
