Leesa Original  Mattress Review

The Leesa Original is a fairly low-profile mattress at 10 inches (ours was a little shorter at 25.1 cm or 9.9 inches). It'll easily accommodate standard fitted sheets.

The Leesa Original is a Medium mattress and a good option for heavier individuals, as it offers good support for back/stomach sleeping and excellent body conformity for pressure relief when side sleeping. It's also a great option for average-weight side sleepers.

However, it's not as supportive for average-weight and lighter individuals, so it's less well-suited for back/stomach sleepers in those weight categories. It also doesn't offer enough pressure relief for lighter side sleepers.

This mattress is most conforming for average-weight and heavier individuals. Whether you are an average or heavier-weight individual, your arms and shoulders sink in enough for proper pressure relief when side sleeping. However, like many Medium mattresses, it's not as conforming for lighter people. While it offers a passable performance for people in that weight category, if you mostly sleep on your side, you'll want a more conforming mattress.

This mattress is most supportive for heavier people. It offers a good performance for people in that weight category, making it a good option for back and stomach sleepers who don't like the feel of firmer mattresses. You'll sink into its soft comfort layers quite significantly, but its firmer support layer prevents your hips from sinking in overly far. This helps keep your spine aligned, which is important for comfortable back and stomach sleep and can help prevent back pain caused by your mattress.

It only offers decent support for average-weight people and okay support for lighter people, who will also sink into the comfort layers, but engage less with the firmer support layer. This makes it a satisfactory option for back/stomach sleep, especially if you sometimes sleep on your side and want good pressure relief, but it won't keep your spine as aligned as some mattresses.

This mattress isn't bouncy. Compared to springier models, changing sleeping positions requires more effort, since you won't feel the mattress push back against your movements.

You'll sink quite far into the mattress overall, but the sleeping surface isn't very contouring. This makes it a decently enveloping mattress, because you'll feel like you're sleeping 'in' the mattress instead of just 'on' it. However, it doesn't mold around you very closely, so you won't feel tightly hugged, and it feels less enveloping overall than some more highly contouring mattresses.

The sleeping surface has a very responsive feel. It responds quickly when you move, so you won't feel stuck in place.

This mattress has great motion isolation overall. It only does an okay job of preventing you from feeling movements, so you'll feel even smaller movements like your cat jumping onto the foot of the bed or your partner shifting slightly. However, it's fantastic at keeping movement localized, so you'll only feel movement near its source. Motion also dissipates incredibly quickly, so the mattress never bounces or wobbles after someone moves.

The Leesa Original has sub-par edge support. There's no additional component like firmer foam along the edges, and you'll sink in quite a bit when you sit on the side of the bed. The edges also form a steep ramp outward under pressure, so if you sleep near the side of the bed, you may feel at risk of sliding off the mattress.

This mattress offers great cooling and will help keep hot sleepers cool throughout the night. It doesn't feel warm during the first hour you're in bed, and continues to dissipate heat very efficiently overnight, so you won't feel like it's gradually heating up as you sleep.

The cover is made of a blend of polyester and viscose, a type of rayon made from cellulose. The manufacturer doesn't provide instructions about whether or not to remove it, but it's not machine-washable.

This mattress's edges aren't reinforced with anything, such as firmer foam or springs. Some firm all-foam mattresses with a similar design still provide good edge support, but in this case, it results in sub-par edge support.

The upper comfort layer is made of responsive memory foam. Like traditional memory foam, this foam has a higher density than most polyfoam you'll find in mattresses, but gel beads added to the foam give it a more responsive feel. Gel-infused memory foam is also marketed as offering better cooling than regular memory foam. The transition layer is made of regular memory foam and is less responsive, although since it's under a more responsive layer, it doesn't make the mattress feel slow-moving overall. The support layer is made of polyfoam, which is typical of all-foam mattresses and is firmer and bouncier.

It's a moderately durable mattress. The responsive gel-infused memory foam and memory foam layers don't meet the density standard for good-quality memory foam and will be prone to showing signs of wear, like body impressions, sooner than higher-quality foams. This can affect the mattress feel, making it feel like the mattress is sagging rather than supporting you. The polyfoam support layer is of good quality, which will help the mattress maintain its overall support for longer, especially if you sink into the upper layers enough to engage with it.

This mattress has a little over 10 cm (4.0 inches) of medium-soft comfort foam, including its 5.5 cm (2.2 inches) responsive memory foam comfort layer and 5.0 cm (2.0 inches) memory foam transition layer. The support layer is 14.9 cm (5.9 inches) thick, giving the mattress a fairly low profile overall compared to some all-foam models like the Novaform Serafina Pearl.

The responsive memory foam upper comfort layer and regular memory foam transition layer both have a medium-soft firmness level, which allows higher sinking and helps with pressure relief. The support layer is much firmer, which helps prevent the heavier parts of your body from sinking in overly far, especially for individuals who sink further into the upper layers. It also makes it firmer overall than similar mattresses with softer support layers, like the Medium-Plush Silk & Snow Mattress.

The upper comfort layer of responsive memory foam is somewhat resilient, or bouncy. It's not extremely slow-moving, but it doesn't feel springy or give a strong 'push back'. The transition layer, made of typical non-gel memory foam, is much less resilient than you'd expect from memory foam, which is usually less bouncy and springy. The polyfoam support layer is much more resilient, contributing to the mattress's slight bounce.
