Flo Mattress keeps its lineup easy to read: Ergo is the softer memory-foam option , Ortho is the firmer orthopedic model, Anti-Gravity uses latex for more lift, and Float is the spring-based pick . In our testing, that clear separation helped, but the feel shifts between models are large enough that choosing the wrong one is easy.

Product Overview
| Mattress | Overall Score (5-point) | Best At | Main Tradeoff | Best For |
|---|---|---|---|---|
| Flo Ergo | 4.0 | Pressure relief and motion isolation | Warmer, slower feel | Side sleepers and couples |
| Flo Ortho | 4.2 | Firm support and alignment | Can feel too hard at the shoulders | Back and stomach sleepers |
| Flo Anti-Gravity | 4.3 | Balanced lift and easy movement | More bounce than foam | Combination sleepers and hot sleepers |
| Flo Float | 4.3 | Cooling, edge support, and responsiveness | Spring feel is more noticeable | Couples and sleepers who like a livelier bed |
Final Verdict
In our testing, Flo Ergo was the clearest pick for side-sleep pressure relief and quiet motion control. Flo Ortho worked best when we wanted a flatter, firmer surface. Flo Anti-Gravity gave the most balanced mix of support, bounce, and cooling, while Flo Float felt easiest to move on and most “hotel-like.” If you are unsure, start with feel first, not marketing category: deep contouring, firm support, latex lift, or springy response.

How We Tested It
We rotated all four models through the same bedroom setup and scored them using the same mattress testing workflow for support , cooling , pressure relief , motion isolation , responsiveness , edge support , and durability . Our testing notes focused on alignment, pressure buildup, temperature, edge security, and ease of movement, and all performance scores below use a 5-point scale.
Flo Mattress: Our Testing Experience
Flo Ergo
Our Testing Experience
In our testing, Ergo delivered the deepest cradle in the lineup. It let the shoulder and outer hip sink in more naturally than the other models, and partner movement stayed very muted. The tradeoff was obvious: it felt slower to turn on, and it held more warmth than the latex and spring options.
What we liked
-
Strong pressure relief at the shoulders and hips
-
Very low partner disturbance
-
Comfortable, settled feel for long back-sleep stretches
Who it is best for
-
Side sleepers who want a true sink-in feel
-
Couples sensitive to movement

Sleepers who prefer slower memory-foam contouring
Where it falls short
-
People who want quick rebound

Anyone who needs firmer sitting edges
Pros & Cons
| Pros | Cons |
|---|---|
| Deep contouring | Slower response |

Flo Ortho
Our Testing Experience
Ortho felt the flattest and firmest in our testing. It kept the hips from dipping and made back- and stomach-sleeping feel steady, especially during longer stretches. It was also easier to sit on and get up from than Ergo. The downside was clear on our side-sleep runs, where shoulder pressure built faster.
What we liked
-
Very steady lumbar and hip support
-
Easier movement than deep memory foam
-
More secure edge feel for sitting
Who it is best for
-
Back sleepers wanting firmer alignment
-
Stomach sleepers who need hip support
-
Sleepers who dislike deep sink
Where it falls short
-
Side sleepers with sensitive shoulders
-
Anyone chasing plush comfort
-
Lighter sleepers who prefer a softer top
Pros & Cons
| Pros | Cons |
|---|---|
| Firm, stable support | Less forgiving at the shoulders |
| Better edge confidence | Not a plush feel |
| Good motion control for a firm bed | Can feel too hard for lighter bodies |

| Durability | 4.3 | Firmer build should hold shape well |
| Overall Score | 4.2 | Firm support first |
Flo Anti-Gravity
Our Testing Experience
Anti-Gravity felt the most balanced in everyday use. In our testing, it gave more lift than Ergo but less hardness than Ortho, so switching positions felt quick without losing support. It also stayed noticeably less clingy on warm nights. The main drawback was that the latex bounce made movement more noticeable than on the all-foam models.
What we liked
-
Balanced mix of support and pressure relief
-
Cooler, less sticky surface feel
-
Fast, easy position changes
Who it is best for
-
Combination sleepers
-
Hot sleepers who dislike foam cling
-
Sleepers who want buoyant support
Where it falls short
-
People who want deep memory-foam sink
-
Very motion-sensitive couples
-
Anyone who dislikes bounce
Pros & Cons
| Pros | Cons |
|---|---|
| Buoyant support | More bounce than memory foam |
| Cooler feel | Not as plush as Ergo |
| Easy mobility | Livelier surface response |

Flo Float
Our Testing Experience
Float was the easiest model to move around on. In our testing, the pocket spring core gave it the quickest pushback, the coolest core feel, and the strongest edge support in the group. It also felt the most like a classic hotel mattress. The tradeoff was that the surface stayed livelier than the foam models, so very quiet sleepers may prefer Ergo.
What we liked
-
Fast response for rolling and getting up
-
Stronger airflow through the core
-
Best edge support in the lineup
Who it is best for
-
Sleepers who like a springier feel
-
Hot sleepers
-
Couples who want better mobility and edges
Where it falls short
-
People who want a dead-still surface
-
Anyone who dislikes coils
-
Sleepers wanting a plush, slow cradle
Pros & Cons
| Pros | Cons |
|---|---|
| Very responsive | Spring feel is more obvious |
| Cooler airflow from coils | Not as quiet as all-foam |
| Strong sitting edge | Less plush than Ergo |

How to Choose the Flo Mattress?
Start with the feel you want. Ergo is the best fit if you want a slower contouring surface. Ortho works better if you want firmer support and a flatter posture. Anti-Gravity is the better middle ground if you want cooling and easier movement without a hard feel. Float is the clearest fit if you like springs, stronger edges, and quick response.
-
Side sleepers : Ergo first, Anti-Gravity second
-
Back sleepers : Ortho or Anti-Gravity
-
Hot sleepers : Float or Anti-Gravity
-
Couples who hate motion transfer : Ergo first
Limitations
-
Flo Ergo: warmer feel, slower rebound, softer sitting edge.
-
Flo Ortho: less forgiving for side-sleep pressure and not very plush.
-
Flo Anti-Gravity: more bounce, less deep contouring, livelier surface.
-
Flo Float: springier feel, more noticeable movement than all-foam, less cradle.
Flo Mattress Vs. Alternatives
Flo makes more sense if you want a small lineup with very distinct feels, a 100-night trial, and easy good/better/best separation between foam, latex, and spring builds. If you want denser memory-foam contouring, a more traditional luxury innerspring , or a natural-latex-forward alternative , Tempur-Pedic Adapt, Saatva Classic, and Avocado Green are the clearer comparison points.
Pro Tips for Flo Mattress
-
Choose the feel first, then the thickness.
-
If you sleep hot, start with Float or Anti-Gravity.
-
If you share the bed, pay extra attention to motion isolation.
-
Use a supportive foundation so the mattress does not feel softer than intended.
-
Give the bed and pillow setup a few nights before judging pressure relief .
