Most MLILY mattresses come in two feels: 1.0 Firmer, with structured support and minimal sink, and 3.0 Plusher, with deeper contouring and pressure relief. But those labels only compare two versions of the same mattress. Each collection has its own range, so a 3.0 Plusher in one collection can feel firmer than a 1.0 Firmer in another, and "medium" depends on which mattress you're looking at. The ChiroPro 3.0 Plusher and the Midnight ICE 1.0 Firmer, for example, both land right at medium. The best way to find your feel is to try it at one of more than 1,500 MLILY retailers.
Key takeaways
- 1.0 Firmer is the firmest version of a collection and 3.0 Plusher is the plushest. PowerCool uses Firm and Medium, and the Manchester United Dream comes in a single medium feel.
- The labels are relative. They compare two versions of the same mattress, not mattresses across collections.
- "Medium" lives in a different version depending on the mattress: the 3.0 Plusher in ChiroPro, the 1.0 Firmer in Midnight ICE.
- Within a hybrid collection, 1.0 and 3.0 share the same coil support. The difference is in the comfort layers on top.
- Shop by where a mattress lands on the scale, not by the word on the tag.
What 1.0 Firmer and 3.0 Plusher mean at MLILY
Most MLILY mattress collections are offered in two firmness options. Here's how MLILY describes each:
| 1.0 Firmer | 3.0 Plusher | |
|---|---|---|
| How it feels | Structured support with minimal sink | Deeper contouring and cushioning for more pressure relief |
| Recommended for | Back and stomach sleepers | Side sleepers, or anyone who wants deeper pressure relief |
| Offered on | ChiroPro Tri-Zoned Hybrid, WellFlex, WellFlex ICE, Midnight Hybrid, Midnight ICE Hybrid | |
Two collections use different names. The PowerCool Sleep System comes in Firm (for back and stomach sleepers) and Medium (for combination and side sleepers), and the Manchester United Dream comes in a single medium feel.
Why a 3.0 Plusher can be firmer than a 1.0 Firmer
There is no industry standard for how firm "firmer" or how soft "plusher" has to be. At MLILY, the labels describe the two ends of each collection's own range. Each collection is designed with a purpose, and that purpose decides where its range starts and ends.
The ChiroPro Tri-Zoned Hybrid, developed with the International Chiropractors Association, is built around targeted, zoned support, so its whole range leans firm. Even its 3.0 Plusher only gets as soft as medium. The Midnight ICE Hybrid is built for a pressure-relieving, premium hotel feel, so its whole range leans soft. Even its 1.0 Firmer only gets as firm as medium.
The result: the ChiroPro 3.0 Plusher and the Midnight ICE 1.0 Firmer feel about the same. And the WellFlex ICE 1.0 Firmer, at firm, is firmer than the Midnight 3.0 Plusher by a wide margin, while the Midnight 1.0 Firmer is actually a touch firmer than the WellFlex 3.0 Plusher. A label only tells you which way to go within a collection, so a 1.0 Firmer can actually be a medium. To find your feel, compare across mattresses, not just between the 1.0 and 3.0 of one model.
Where is "medium"? It depends on the mattress
If you're looking for a medium feel, the version you want changes from collection to collection. In some collections medium is the Plusher, in one it's the Firmer, and in others it falls in between. Here's where to find medium in each MLILY mattress:
| Mattress | Closest to medium | What that means |
|---|---|---|
| ChiroPro Tri-Zoned Hybrid | 3.0 Plusher | Right on medium. The 1.0 Firmer is extra firm. |
| Midnight ICE Hybrid | 1.0 Firmer | Right on medium. The 3.0 Plusher is luxury plush. |
| Manchester United Dream | Its single feel | Medium, with no other option to choose. |
| WellFlex | 3.0 Plusher | Just past medium, on the soft side. The 1.0 Firmer is near extra firm. |
| PowerCool Sleep System | Medium | Just past medium, on the soft side. Firm sits between firm and medium firm. |
| Midnight Hybrid | 1.0 Firmer | Between medium firm and medium, on the firm side. The 3.0 Plusher is near luxury plush. |
| WellFlex ICE | Neither exactly | Medium falls between its 1.0 Firmer (firm) and 3.0 Plusher (medium plush). |
So if a friend tells you they "got the medium," it's worth asking which mattress. A medium ChiroPro is a 3.0 Plusher, while a medium Midnight ICE is a 1.0 Firmer.
The MLILY firmness scale
Here's every adult MLILY mattress collection on one shared scale. The left dot is the firmest version and the right dot is the plushest. The gold dashed line marks true medium.
Read it left to right: the further right a dot sits, the softer that model feels. ChiroPro's plushest model and Midnight ICE's firmest model meet on the same line. The Manchester United Dream, which comes in a single medium feel, would sit right on the gold line.
Quick game: which one is firmer?
Test your label-reading skills. Guess first, then tap to reveal.
ChiroPro 3.0 Plusher or Midnight ICE 1.0 Firmer?
It's a tie. Both land right on medium. One says plusher and one says firmer, and they meet in the middle.
WellFlex 3.0 Plusher or Midnight 1.0 Firmer?
Midnight 1.0 Firmer, but only slightly. Midnight's firmest sits between medium firm and medium, while WellFlex's plushest sits just past medium. Close neighbors with opposite labels.
PowerCool Medium or WellFlex ICE 3.0 Plusher?
PowerCool Medium. WellFlex ICE 3.0 sinks a little deeper into medium plush territory, thanks to its extra cooling foam.
What changes inside: 1.0 Firmer vs 3.0 Plusher
Firmness is how the top of the mattress feels. Support is how well it keeps your spine aligned, and it comes from the core. In MLILY's hybrids, the 1.0 and 3.0 versions use the same pocketed spring support. What changes is the comfort layers on top: the 3.0 Plusher swaps firmer transition foams for softer, more contouring ones, like Latex-like AdaptiFoam® and Liquid Gel CoolFlex™ Foam.
| Collection | 1.0 Firmer comfort layers | 3.0 Plusher comfort layers | Shared support |
|---|---|---|---|
| ChiroPro Tri-Zoned Hybrid | 1.5" Gel AeroFusion® Memory Foam, 1.5" Gentle Flex Foam, 1" Flex Comfort Foam | 1.5" Gel AeroFusion® Memory Foam, 1.5" Latex-like AdaptiFoam®, 1" Liquid Gel CoolFlex™ Foam | 8" 3-zone pocketed springs |
| Midnight Hybrid | 1.5" Copper Gel AeroFusion® Memory Foam, 1.5" Gel AeroFusion® Memory Foam, 2" Gentle Flex Foam | 1.5" Copper Gel AeroFusion® Memory Foam, 1.5" Latex-like AdaptiFoam®, 1.5" Liquid Gel CoolFlex™ Foam | 6" pocketed springs |
| Midnight ICE Hybrid | 1.5" Copper Gel AeroFusion® Memory Foam with ActiveTemp™ PCM, 2.5" Gel AeroFusion® Memory Foam, 2.5" Gentle Flex Foam | 1.5" Copper Gel AeroFusion® Memory Foam with ActiveTemp™ PCM, 2" Latex-like AdaptiFoam®, 1.5" Gel AeroFusion® Memory Foam, 1.5" Liquid Gel CoolFlex™ Foam | 6" pocketed springs |
| WellFlex | 1" BioBreeze™ Memory Foam, 2" Performance Memory Foam over a 9" support base | 1.5" Gel AeroFusion® Memory Foam, 1.5" BioBreeze™ Memory Foam, 2" Liquid Gel CoolFlex™ Foam, 1.5" Flex Comfort Foam over a 5.5" support base | Flex Support Base Foam |
| WellFlex ICE | 1.5" Gel AeroFusion® Memory Foam with ActiveTemp™ PCM, 1" BioBreeze™, 2" Performance Memory Foam over a 9.5" support base | 1.5" Gel AeroFusion® Memory Foam with ActiveTemp™ PCM, 2.5" BioBreeze™, 2" Liquid Gel CoolFlex™, 2" Flex Comfort Foam over a 6" support base | Flex Support Base Foam |
In the all-foam WellFlex models, the 3.0 Plusher trades some of the thick support base for extra comfort foam, which is why it contours more deeply. Comparing a standard model with its ICE version? Read our WellFlex vs WellFlex ICE and Midnight vs Midnight ICE guides.
Which feel is right for you?
Start with how you sleep, then pick the model that lands in your zone, whatever its label says.
If you sleep on your side
Your shoulders and hips need room to sink in. Aim for medium to plush: Midnight 3.0 Plusher, Midnight ICE 3.0 Plusher and WellFlex ICE 3.0 Plusher all live here.
If you sleep on your back
You want your lower back supported without your hips sinking. Medium firm to medium is the sweet spot: ChiroPro 3.0 Plusher, Midnight 1.0 Firmer, PowerCool or Midnight ICE 1.0 Firmer. A 2021 review of mattress studies found that medium-firm mattresses offer the most advantages for people with non-specific low back pain.
If you sleep on your stomach
Keep your hips level with your shoulders by going firm: ChiroPro 1.0 Firmer, WellFlex 1.0 Firmer and WellFlex ICE 1.0 Firmer sit on the firm side. Learn more in our guide to stomach sleeping.
If you switch positions or share the bed
Medium is the easiest compromise. ChiroPro 3.0 Plusher, Midnight ICE 1.0 Firmer and the Manchester United Dream sit right on the medium line, with WellFlex 3.0 Plusher and PowerCool Medium close by.
A note on body weight
A heavier sleeper presses deeper into the comfort layers, so a mattress feels softer to them than to a lighter sleeper. If you're on the heavier side, shift one step firmer than your sleep position suggests. If you're lighter, shift one step softer.
