The Puffy Monarch is a 16-inch luxury hybrid bed-in-a-box mattress with a Medium-Plush firmness level. It has a thick base layer of pocketed coils for support, topped with layers of latex and foam for comfort. The comfort layers are zoned, with different latex cutouts at the hips versus the head and feet for targeted pressure relief. The cover is what Puffy calls a Cool TENCEL cover, quilted over a layer of alpaca wool, the brand says, which the brand says helps wick away moisture. All foam used is CertiPUR-US certified, and it's assembled in the USA.

The Puffy Monarch mattress is best suited for average-weight and heavier side sleepers. Heavier sleepers sink in more, so the comfort layers cushion their shoulders and hips. Lighter side sleepers don't sink in as far and get less cushioning at those pressure points. The comfort layers will envelop you closely, adding additional cushioning, especially for heavier people.
Excellent pressure relief for heavier-weight side sleepers.
Great pressure relief for average-weight side sleepers.
Decent pressure relieve for lightweight side sleepers.

The Puffy Monarch mattress isn't the best choice for back sleepers unless they're lightweight. Back sleepers need a firm enough surface to keep their hips from sinking below their shoulders and pulling their spines out of alignment, and this mattress has a Medium-Plush feel, so it's too soft for most back sleepers. Lighter people rest on top of the comfort layers and don't sink in as much, whereas heavier people sink in further and don't get enough support.
Good support for lighter back sleepers.
Only passable support for average people.
Mediocre support for heavier people.

The Puffy Monarch mattress isn't ideal for stomach sleeping. Most stomach sleepers need a firmer mattress to prevent their hips from sinking too far into the material, and this model has a Medium-Plush feel. It'll offer decent support for lighter stomach sleepers and will keep their spines relatively well-aligned, but it's not a good option for average-weight and heavier stomach sleepers who won't receive enough support.
Decent support for lighter stomach sleepers.
Doesn't provide enough support for average-weight and heavier stomach sleepers.

Test Results
Longevity
The Puffy Monarch isn't a very durable mattress. Neither the foam used in the upper comfort layer nor the transition layer meets our density standard for good-quality foam. The latex layer between them is denser and should hold up better, but you're still likely to see permanent body impressions forming over time.
Uses largely low-quality foam that will show signs of wear sooner.
The upper comfort layer is made up of latex. Below the latex sits a layer labeled as memory foam, though it actually behaves more like a gel-infused, responsive polyfoam. Rather than the slow, sinking hug you'd expect from true memory foam, it springs back more quickly. A polyfoam transition foam sits below the comfort layers.
Both the latex and polyfoam have different scalloping patterns at the lumbar versus the head and feet, creating zones that flex differently depending on which part of your body is resting on them, which lines up with the firmer feel at your head and feet compared to your hips.
Most of the foam used to construct this mattress isn't dense enough to be considered high quality. The material right under the cover, which is what your body presses into most, falls short of what you'd want for long-term durability, and the transition layer isn't particularly dense either. The latex layer in between holds up better, but it's not enough to offset those weaker points. Over time, this combination means you're more likely to see permanent body impressions form, and the mattress can start to feel like you're sleeping in a shallow dip rather than on an even surface.
Pressure Relief
The Puffy Monarch offers great pressure relief, which matters most if you sleep on your side, since that position puts most of your weight on your shoulders and hips. Average and heavier sleepers sink in enough for the comfort layers to spread that weight out and ease pressure on their joints. Lighter sleepers still get decent relief, but they don't sink in as far, so the weight isn't spread out quite as much. The comfort layers also hug your body as you sink in, adding a bit more cushioning.
Outstanding pressure relief for average-weight and heavier sleepers.
Decent pressure relief for lighter people.
The Puffy Monarch conforms to your body very well, which matters most for side sleepers who need their shoulders and hips to sink in for pressure relief. That said, it depends on your body weight. Lighter people will get some pressure relief, but average-weight and heavier people get the best results because they sink in deeper.
Support
The Puffy Monarch doesn't offer enough support for most people, which is especially important if you sleep on your back or stomach. It's more supportive for lighter people who don't sink as far into the mattress, but heavier people may wake up with aches and pains because it isn't firm enough to keep their spines properly aligned.
Decent support for lighter people.
Only passable support for average people.
Mediocre support for heavier people.
This mattress provides adequate support for people who sleep on their backs or stomachs, though the level of support varies depending on your weight. It's most supportive for lighter people, who don't sink as far into the mattress. Heavier people sink in further, which may cause their spines to become misaligned throughout the night.
Cooling
The Puffy Monarch has very good cooling performance, so most people should stay comfortable through the night without overheating. It starts off reasonably cool as you settle in, and the warmth builds up gradually, so you're less likely to wake up hot in the middle of the night. That said, it isn't cooling enough for very hot sleepers, who should look for a mattress that performs better in this category.
Starts off reasonably cool, so you're comfortable as you fall asleep.
Not quite cool enough for hot sleepers to stay fully comfortable through the night.
Motion Dissipation
The Puffy Monarch does a great job of dissipating motion, making it a good choice if you share a bed with a restless partner or pet. If your partner shifts around or a pet jumps onto the bed, it may cause the bed to wobble for a moment. You'll feel motion close to where it happens, but it won't ripple across the entire bed.
Motion dissipates quickly.
You'll feel movement near the source but not across the entire bed.
This mattress does an impressive job of isolating motion, so it's a great pick if you share your bed with a restless partner. If your partner shifts around or a pet jumps onto the bed, you'll feel it close to where it happens, but the movement won't cause the entire mattress to bounce or wobble.
Responsiveness
The Puffy Monarch is relatively responsive, so switching positions or moving around at night doesn't take much effort. The surface re-conforms to your body at a moderate pace after you shift, and it pushes back enough to help you reposition without much resistance. It won't feel as quick or springy as a traditional innerspring mattress, but you won't get that feeling of being stuck.
Relatively easy to move around or change positions.
You won't feel "stuck" in the mattress.
The quilted top layer, latex, and transition foam layers are quite resilient, creating a somewhat bouncy feel despite the less resilient memory foam layers between them.
The Puffy Monarch is a 16-inch mattress, though our model didn't expand fully and measured at 15.2 inches. Regardless, you'll need a deep-pocket fitted sheet.
This mattress has a Medium-Plush firmness level, with more give at your hips than at your head and feet, so the softest part of the mattress lines up right where a side sleeper's shoulder and hip need pressure relief. It's best suited to heavier and average-weight side sleepers, because they'll compress the comfort layers enough to feel that cushioning, whereas lighter side sleepers don't sink in as much. If you sleep on your back or stomach, this firmness level only really works if you're on the lighter side, since it doesn't offer much resistance to keep your hips in line with your spine.
The Puffy Monarch has mediocre edge support, so the mattress gives way more than you'd want if you sleep or sit near the edge. If you and a partner share the bed, it reduces how much of the usable surface feels stable, and you may feel like you're about to roll off if you drift too close to the edge overnight. It also makes sitting on the edge, like when you're getting dressed or getting in and out of bed, feel less secure than it would on a mattress with firmer edge support.
While there's polyfoam reinforcing the edges of the support layer, edge support is still just mediocre.
This mattress has thick layers of foam and latex above the pocket springs, providing plenty of cushioning. That works well if you're a side sleeper, since there's enough depth for your shoulder and hip to sink in fully for pressure relief. If you sleep on your back or stomach, though, you'll sink further before hitting material firm enough to keep your spine aligned.
Popular Mattress Comparisons
The Puffy Monarch is a luxury hybrid mattress that sits at the top of Puffy's lineup, positioned above the Puffy Lux and Puffy Royal. It has a Medium-Plush feel, making it the softest model of the mattresses we've tested from the brand. It's best suited for average and heavier side sleepers who want a soft, cushioned feel. It holds its own on cooling too, staying comfortable enough for most people through the night.
Where the Monarch falls short is in durability and edge support. Aside from one layer of good-quality latex, its comfort layers use lower-density foam that's likely to wear down faster than average, and the edges give way more than you'd want if you sit or sleep near the side of the bed. It's also not the right pick if you sleep on your back or stomach, especially at a heavier weight, since the soft comfort layers let your hips sink out of line with your spine. The Casper Snow Max offers better support across the board, along with even stronger cooling, though its memory foam comfort layers aren't as responsive. If you want something firmer that's best for back and stomach sleeping, consider the Avocado Green mattress.

The Puffy Monarch and Puffy Lux are both hybrid bed-in-a-box mattresses, but they land at different firmness levels: the Monarch's Medium-Plush feel offers deeper cushioning at the shoulders and hips for average and heavier side sleepers, while the Lux's firmer Medium feel is a better match for lighter side sleepers. The Monarch cools a bit better overnight, but the Lux is more responsive, giving it a livelier, easier-to-reposition-on feel. Edge support leans slightly in the Lux's favor, too, so you'll feel more secure sitting or sleeping along the edge of that mattress. Neither one is particularly durable, since both rely on lower-density foam in their comfort layers, which is prone to wearing down over time.
The Puffy Monarch and Puffy Royal sit on opposite ends of Puffy's lineup when it comes to their firmness level: the Monarch's Medium-Plush feel is better for average and heavier side sleepers who want deep pressure relief at the shoulder and hip, while the Royal's Medium-Firm feel is built for lighter and average back and stomach sleepers who need their hips kept in line with the rest of the spine. The Royal is also more responsive of the two, bouncing back quickly and letting you change positions more easily. The Monarch is better for a partner sharing the bed, since motion settles down faster. Edge support is a weak point on both mattresses, and neither is especially durable given the lower-density foam each uses in its comfort layers.
The Puffy Monarch and Saatva Classic (Plush Soft) are both Medium-Plush hybrid mattresses that relieve pressure well for average and heavier side sleepers, letting you sink in enough for real cushioning at the shoulder and hip. Neither model is firm enough to be ideal for back or stomach sleeping. Where they differ is in the details that shape your day-to-day experience: the Monarch does a better job keeping a partner's movements from reaching your side of the bed, while the Saatva holds its shape better at the edges and moves more easily under you when you shift positions at night. Neither mattress is especially durable, since both rely on lower-density foam in their comfort layers that's likely to wear down over time.
The Puffy Monarch and Casper Snow Max are both hybrid mattresses that relieve pressure well for average and heavier side sleepers, but the similarities mostly end there. The Snow Max keeps your hips more level if you sleep on your back or stomach, thanks to its firmer support layer. It also runs cooler and offers better motion isolation, making it ideal if you share a bed with a restless partner.
Where the Monarch pulls ahead is responsiveness: its latex layer pushes back and lets you reposition easily, while the Snow Max's memory foam-heavy composition responds slowly and can feel harder to move around on.
