Milliard is common in budget foam, especially folding mattresses for guests and small spaces. We tested how these beds feel in real use.
We tested five options: the 10-inch Classic Firm, two tri-fold floor mattresses (6-inch memory foam and 4-inch foam), a 4.5-inch sofa bed, and a dual-sided crib/toddler mattress. We scored support, pressure relief, cooling, motion isolation, responsiveness, and value.
Table of Contents
Product Overview
| Mattress | Pros | Cons | Ideal For | Price* | Overall Score |
| Milliard 10-Inch Classic Firm Memory Foam Mattress | Strong support for back sleepers, solid motion control, very good value | Runs firm for lighter side sleepers, average cooling, basic look | Budget-minded back sleepers, teens, guest rooms needing real support | About $230–$350 in queen, depending on retailer | 4.3 / 5 |
| Milliard 6-Inch Tri-Fold Memory Foam Mattress | Folds quickly, thicker than many tri-folds, supportive for short stays | Too thin for full-time heavier use, hinge lines visible through sheet | Guests, gaming rooms, RVs, small apartments | Usually $200–$300 for Full or Queen | 3.9 / 5 |
| Milliard 4-Inch Tri-Fold Foam Mattress | Very compact, light to move, low price | Limited support for adults, best for short visits only | Kids’ sleepovers, floor lounging, emergency extra bed | Usually $110–$190 | 3.7 / 5 |
| Milliard 4.5-Inch Tri-Fold Sofa Bed Mattress | Converts from couch to mattress, good pressure relief for short use | Low seating height, still thin for heavier adults as a nightly bed | Studio apartments, multipurpose rooms, small guest spaces | Typically under $200 for queen size | 3.8 / 5 |
| Milliard Crib and Toddler Dual-Sided Mattress | Firm infant side, softer toddler side, waterproof cover | Mild heat build-up under some babies, edges not like a mini-rail | Parents wanting one crib mattress from infancy through toddler years | Typically $105–$150 | 4.3 / 5 |
Testing Team Takeaways
The big takeaway from this test: Milliard works best when you buy for a specific use case. The 10-inch bed is built for daily sleeping, while the folding models trade height and edge strength for portability and storage.
The 10-inch Classic Firm delivered the most consistent alignment in our group, especially for back and stomach sleeping. It also did a great job limiting motion transfer, but the feel is firm enough that some side sleepers will notice shoulder pressure.
For adult guests, the 6-inch tri-fold was the most comfortable of the folding options. The 4-inch tri-fold is easier to move and store, but we’d treat it as a short-term crash pad, kids’ mattress, or floor lounger rather than a true guest bed.
The 4.5-inch sofa bed was the most flexible for small spaces—quick to switch between couch mode and a sleep surface. The crib/toddler mattress was the outlier: very firm on the infant side, slightly more forgiving on the toddler side, and practical thanks to the snug fit and wipeable cover.
Milliard Mattress Comparison Chart
| Mattress | Firmness (our view) | Thickness | Construction | Sizes | Cooling Performance | Support | Pressure Relief | Responsiveness | Motion Isolation | Durability Expectation |
| 10-Inch Classic Firm Memory Foam Mattress | Firm for most sleepers | 10" | All-foam design with memory foam over high-density base, CertiPUR-US foams | Twin, Full, Queen, King | Moderate; classic foam feel with basic airflow | Strong for back and some stomach sleepers | Moderate for side sleepers, better for heavier bodies | Slower response on top, steady push from base | Very good for couples and restless partners | High for price tier, dense base foam feel |
| 6-Inch Tri-Fold Memory Foam Mattress | Medium-firm in our tests | 6" | Folding mattress with memory foam comfort layer over support foam base, three panels | Twin, Full, Queen | Slightly cooler than the 10-inch due to thinner profile | Decent for guests and lighter to average sleepers | Gentle cushioning at shoulders and hips, limited depth | Quick to move on, panels help repositioning | Good for most guest setups | Solid if used part-time and stored properly |
| 4-Inch Tri-Fold Foam Mattress | Medium feel at first, softer under weight | 4" | Folding foam mattress with thinner comfort and base layers | Twin, Full, Queen | Fair; thin foam dumps heat faster yet compresses quicker | Limited for adults, fine for kids and very short stays | Enough comfort for naps or a weekend | Very easy to move around on | Acceptable for short-term use | Moderate, best as occasional mattress |
| 4.5-Inch Tri-Fold Sofa Bed Mattress | Medium, slightly plusher top | 4.5" | Tri-fold foam design that converts between couch and mattress | Full, Queen | Average; depends strongly on room temperature and bedding | Adequate for guests and lighter adults | Nice contour for shoulders during short runs | Bouncy feeling for all-foam, easy flipping between modes | Good for one restless sleeper, fair for two | Good if folded and unfolded with some care |
| Crib and Toddler Dual-Sided Mattress | Infant side firm, toddler side medium | Around 5–5.5" | Dual-sided foam core with waterproof yet breathable style cover | Standard U.S. crib size | Slight warmth under very insulated sleepers, manageable | Excellent infant support with snug crib fit | Better on toddler side, still safe for young bodies | Quick surface response for rolling toddlers | Excellent; crib size limits partner disturbance anyway | High as far as budget crib mattresses are concerned |
What We Tested and How We Tested It
We tested each Milliard mattress in the setting it’s meant for. The 10-inch Classic Firm went on a standard bed frame. The tri-folds were tested on carpet and hard floors with a fitted sheet. The sofa bed was evaluated in both couch mode and flat mode. The crib mattress was checked inside a standard crib frame for fit and firmness.
Support and alignment were the priority. We watched how quickly hips and shoulders sank, whether the lower back stayed neutral, and how stable the midsection felt for back, side, and stomach sleeping.
For pressure relief, we looked for early warning signs—shoulder ache during side sleeping, hip pressure on firmer surfaces, and numbness after longer lounging sessions.
Cooling was based on heat build-up checks under typical bedding and how warm the surface felt after extended contact. None of these mattresses use luxury cooling materials, so we focused on relative differences between models.
We also scored motion isolation (including a basic glass-of-water check), edge support (sit-and-stand tests), responsiveness (how easy it was to change positions), and practicality for the folding models (folding, carrying, storage, and cover care).
Milliard Mattress: Our Testing Experience
Milliard 10-Inch Classic Firm Memory Foam Mattress
Our Testing Experience
We treated the 10-inch Classic Firm as the daily-sleeper baseline in this lineup and spent the most nights on it. On my back, the foam stopped my hips quickly and kept my lower spine neutral—exactly what I want from a firm, budget all-foam bed.
Side sleeping was the trade-off. The surface resisted deeper contour, and I started to notice shoulder pressure after longer stretches. In our group, back and stomach sleepers generally felt more comfortable than petite side sleepers.
Marcus (our heavier tester) liked the stable feel and said it kept his hips level. Ethan, who shifts a lot at night, appreciated that he could roll without feeling stuck, and our motion check showed very little disturbance across the surface.
If you want a straightforward, firm foam mattress for a main bedroom—especially for back sleeping—the Classic Firm was the strongest performer we tested. If you’re primarily a side sleeper, a softer bed (or a topper) is usually the better match.
Pros & Cons
| Pros | Cons |
| Firm, even support for back sleeping | Can feel too firm for petite side sleepers |
| Very strong motion isolation for a budget foam bed | Cooling is average for traditional memory foam |
| Holds shape well when changing positions | Not much plush contour at shoulders/hips |
| Good value for a main-bedroom mattress | Basic feature set compared with premium beds |

Milliard 6-Inch Tri-Fold Memory Foam Mattress
Our Testing Experience
The 6-inch tri-fold was the most adult-friendly folding mattress we tested. Laid flat with a fitted sheet, it felt noticeably more substantial than the 4-inch version, and the memory foam top made the first contact softer than basic foam mats.
On my back, the top layer cradled for a moment before the base foam pushed back, so short overnight tests and long naps didn’t leave my lower back irritated. Side sleeping was workable for shorter stretches, though the panel seams can show up under thin sheets.
Marcus could tolerate it for a weekend, but the edges compressed quickly when sitting and he felt closer to the floor during stomach sleeping. Ethan liked that he could reposition easily. Overall, this is the tri-fold we’d pick for guests and travel setups when you want comfort but still need it to fold away.
Pros & Cons
| Pros | Cons |
| Comfortable enough for weekend guests | Low height can be tough for some people to get up from |
| Folds neatly for storage and travel | Panel seams are slightly noticeable |
| Balanced feel for back and light side sleeping | Edges compress when sitting |
| Washable cover is practical for guest use | Not ideal for heavy sleepers as a daily bed |
Details
- Price: Usually $200–$300 for Full or Queen (varies by retailer)
- Firmness: Medium-firm, around 6–7/10 in our testing
- Thickness: 6 inches
- Construction: Tri-fold memory foam over a support base (CertiPUR-US foams)
- Available sizes: Twin, Full, and Queen
- Cover: Removable/washable cover with a grippy underside
- Best suited for: Weekend guests, travel, and small spaces

Milliard 4-Inch Tri-Fold Foam Mattress
Our Testing Experience
The 4-inch tri-fold is the lightest, simplest option in this group, and it feels that way once you lie down. On my back, it starts comfortable, then compresses toward the floor—especially on hard surfaces.
Mia liked it for a movie night and a first overnight, but she noticed her hip sitting lower as time went on. Marcus bottomed out quickly and treated it more like a crash pad than a guest bed.
We’d use this one for kids’ rooms, sleepovers, camping, or as a floor lounger that stores in a closet. For adult guests staying more than a night or two, the 6-inch tri-fold is the safer bet.
Pros & Cons
| Pros | Cons |
| Very light and easy to move or store | Limited support for adult sleepers, especially heavier bodies |
| Folds into a compact block for closets and car trunks | Feels thin over hard floors, especially under hips |
| Budget-friendly option for kids’ rooms and sleepovers | Panel seams become noticeable over longer sessions |
| Works well as a lounging mat or play surface | Not suitable as a long-term primary mattress |
Details
- Price: Often $90–$170 depending on size and retailer
- Firmness: Medium at first, softening under load—especially for heavier sleepers
- Thickness: 4 inches
- Construction: Tri-fold foam mattress (CertiPUR-US foams)
- Available sizes: Commonly Twin, Full, Queen
- Cover: Zip cover on many versions; easy to fold and store
- Best suited for: Kids, sleepovers, camping, and short stays
Review Score
| Metric | Score | Remarks |
| Support | 3.2 / 5 | Good for light/short use; limited for adults. |
| Pressure Relief | 3.4 / 5 | Comfortable at first; depth runs out. |

| Motion Isolation | 3.5 / 5 | Fine for a solo sleeper. |
| Edge Support | 3.0 / 5 | Edges compress quickly. |

| Durability | 3.7 / 5 | Best under occasional use. |
| Value | 4.6 / 5 | Strong for the price. |
| Overall Score | 3.7 / 5 | Best as a short-term floor option. |
Milliard 4.5-Inch Tri-Fold Sofa Bed Mattress
Our Testing Experience
We tested the 4.5-inch sofa bed in both couch and flat modes. In couch mode, it reads more like a low floor couch than a traditional sofa—comfortable for lounging, but noticeably low for long sit-and-stand cycles.
Flattened out, it felt a touch plusher than the standard tri-folds, with enough give at the shoulders and hips for a few hours of side sleeping. Ethan liked that he could roll without any stuck feeling, and he rated it above most cheap futon-style mattresses.
The trade-off is thickness. Marcus hit the firm base quickly and viewed it as an occasional solution, not a nightly bed. Motion isolation was fine for one active sleeper, but two adults will notice more movement than on the 10-inch bed.
Pros & Cons
| Pros | Cons |
| Converts from couch to mattress in seconds | Very low seating height compared with regular sofas |
| Comfortable enough for short to medium stays | Still thin for heavy adults as a full-time bed |
| Great for studios and multipurpose rooms | Looks casual rather than like traditional furniture |
| Easy to move, fold, and store | Panel seams can show through thin sheets |
Details
- Price: Typically under $200 for a queen size
- Firmness: Medium with a slightly plusher top
- Thickness: 4.5 inches
- Construction: Tri-fold sofa bed design (couch + mattress modes)
- Available sizes: Full and Queen
- Cover: Upholstery-style cover; usually spot-clean
- Best suited for: Studios and multipurpose rooms
Review Score
| Metric | Score | Remarks |
| Support | 3.3 / 5 | Fine for short stays; thin for heavier bodies. |
| Pressure Relief | 3.9 / 5 | Plusher top helps shoulders and hips. |

Milliard Crib and Toddler Dual-Sided Mattress
Our Testing Experience
The crib/toddler mattress is the most purpose-built item in this lineup. The infant side felt very firm—more like a dense pad than a plush mattress—and it snapped back quickly after pressure.
In a standard crib frame, the fit stayed snug around the edges. The cover felt smooth under a fitted sheet and was easy to wipe, which matters more than aesthetics in a nursery.
Flipping to the toddler side brought a clear step toward cushioning without turning soft. Heat build-up stayed mild in our nap-length testing, and the overall construction (stitching, edges, and cover) looked solid for a mattress meant to last across stages.
Pros & Cons
| Pros | Cons |
| Dual-sided design for infant and toddler stages | Very firm feel can surprise parents used to plush beds |
| Fits standard cribs with a snug perimeter | Limited customization beyond flipping sides |
| Waterproof cover makes cleanup easy | Cooling is only average under thick bedding |
| Good value for a multi-stage crib mattress | Not designed to feel soft or plush |
Details
- Price: Typically $105–$150 (sales can drop it lower)
- Firmness: Firm infant side, slightly softer toddler side
- Thickness: Around 5–5.5 inches
- Construction: Dual-sided foam with a waterproof outer layer
- Size: Standard U.S. crib mattress size
- Cover: Waterproof cover; wipeable and easy care
- Best suited for: Nursery use from infant to toddler
Review Score
| Metric | Score | Remarks |

Best Picks
- Best for back sleepers on a budget: 10-Inch Classic Firm — firm alignment, excellent motion isolation, strong value.

- Best for studios and small spaces: 4.5-Inch Sofa Bed — quick couch-to-bed conversion and solid comfort for short stays.
How to Choose the Milliard Mattress?
Start with the job you need the mattress to do. A main-bedroom mattress should prioritize alignment and long-night comfort, while a foldable mattress should prioritize portability, storage, and being ‘good enough’ for short stays.
If you like a firm feel (or you sleep on your back or stomach), the 10-inch Classic Firm is the cleanest fit in this lineup. For weekend guests or travel, the 6-inch tri-fold adds enough thickness to feel like a real mattress. The 4-inch tri-fold is best when you care more about easy storage than all-night support.
For small apartments, the sofa bed works well when you need one piece to handle both lounging and occasional sleeping. For nurseries, the crib/toddler mattress stands apart with a very firm infant side and a slightly softer toddler side.
- Main bedroom, firm feel: 10-Inch Classic Firm.
- Weekend guests and travel: 6-Inch Tri-Fold.
- Kids, sleepovers, and ultra-easy storage: 4-Inch Tri-Fold.
- Studio seating + occasional guest sleep: 4.5-Inch Sofa Bed.
- Nursery from newborn through toddler years: Crib and Toddler Dual-Sided mattress.
Limitations
These models share some predictable limits. If you want deep, plush contour or premium cooling features, this lineup may feel too simple—especially compared with higher-end foam or hybrid beds.
For the tri-fold models and the sofa bed, the biggest compromise is height and edge strength. They work well for short stays and multipurpose spaces, but they sit low to the ground and won’t feel like a tall, traditional mattress.

FAQs
What is the best Milliard mattress for everyday adult use?
The 10-inch Classic Firm can work as a daily bed if you like a firm feel. The folding models are better for guests, travel, and temporary setups.
Are Milliard tri-fold mattresses comfortable for guests?
For many side sleepers—especially lighter ones—it can feel stiff at the shoulder. Average-to-heavier side sleepers may tolerate it, but it is not plush.
Do Milliard mattresses sleep hot?
Yes. You can usually feel the panel seams under thin sheets, especially if you land directly on a seam. Thicker bedding helps.
How supportive are Milliard mattresses for heavier sleepers?
It can work for short stays, but it’s best for one sleeper or two people who don’t mind a thinner surface and some motion transfer.
Can I use a Milliard tri-fold mattress as my main bed?
In our check, it fit snugly in a standard U.S. crib frame, which is what you want for crib safety.
Is the Milliard crib mattress safe for infants?
The infant side is very firm, but safety depends on proper fit and following the crib and mattress instructions. If you have concerns, ask your pediatrician.
How durable are Milliard mattresses?
You can place it on a platform or slatted base for easier standing, but keeping it low to the floor is part of the design and storage advantage.
Do Milliard mattresses have strong odors when opened?
Standard fitted sheets worked on the 10-inch bed. For tri-folds, stretchy fitted sheets tend to sit better over the folds and stay in place.
What sheets work best on Milliard tri-fold mattresses?
Fitted sheets sized for each mattress work best. For tri-folds, deeper-pocket sheets can bunch at the fold lines, so simpler fitted sheets usually lay flatter.
