Tuft and Needle Original II   Review

This Medium-Firm mattress's support and pressure relief performance vary a lot depending on your weight, and it's not as versatile as some mattresses with a similar firmness level. It's only suitable for back and stomach sleeping if you're in the lighter weight category, since it only offers good support for people in that weight category. If you're average-weight or heavier, your hips will sink in overly far, and your spine won't stay well-aligned. 

On the other hand, it's a comfortable option for heavier side sleepers, who will sink in more and get great pressure relief. If you're average-weight or lighter, you won't sink in as much, and you'll feel more pressure on your arm and shoulder when side sleeping.

The quilted layer is made of gel-infused memory foam that has a responsive feel, unlike regular memory foam. The upper and lower comfort layers are both made of polyfoam that has an even bouncier feel. These layers don't allow much sinking or have an enveloping feel, although heavier people who sink in more and engage with the lower comfort layer will get much better pressure relief. The transition and support layers are also made of resilient polyfoam, but unfortunately, they don't create good support for most people. 

Most of the foam in the mattress is dense enough to be considered good quality, including the support, transition, lower comfort, and upper comfort layers. However, the foam in the quilted layer doesn't quite meet the standard for good-quality memory foam, and that layer is more prone to forming permanent indentations and impressions. 

This Medium-Firm mattress's body conformity performance depends on your weight. If you're in the lighter weight category, you'll hardly sink in, and it'll put a lot of pressure on your arm and shoulder if you sleep on your side. Its performance is better for average-weight people, but it's still just mediocre, so it won't offer good pressure relief for side sleepers in that weight category either. However, it offers excellent body conformity for heavier people, who will sink in much more, and it's a suitable option for side sleepers in that category. 

This mattress doesn't let your body sink in much overall, so you feel like you're sleeping 'on' instead of 'in' it. The sleeping surface is highly contouring, however, so it molds closely around you, which helps cushion pressure points. 

This mattress's support performance varies depending on your weight. It offers very good support for lighter people, so it'll keep your hips supported and your spine well-aligned whether you sleep on your side, back, or stomach. However, its performance for average-weight people is just okay, so your hips will sink further, which will put your spine out of alignment if you sleep on your back or stomach. Its support for heavier individuals is much worse, and it's an uncomfortable option for back and stomach sleepers in that weight category.

This mattress does a great job of keeping you cool. It has a cooling feel when you first get into bed and does an even better job of dissipating heat over eight hours. Overall, it's a good option for hot sleepers, whether you usually feel overheated as you're falling asleep or often wake up later on feeling hot. 

This mattress has good motion isolation overall. It doesn't dampen movement very effectively, so you'll feel your partner's smaller shifts as well as bigger movements, like someone getting into bed. However, motion stays localized, so it's mostly felt near its source instead of all over the mattress, and it dissipates very quickly, so movements are only felt briefly and don't make the mattress wobble. 

The sleeping surface is extremely responsive, so it bounces back quickly after being compressed, which prevents you from feeling stuck in place.

It has a bouncy feel, so your movements feel supported and it's easy to change sleeping positions. 

The memory foam quilted layer has a somewhat resilient, bouncy feel, so it's not as slow-moving as classic memory foam. The mattress's other layers, made of polyfoam, are even more resilient, which helps give it a bouncy feel overall, especially for an all-foam mattress. 

This mattress has impressive edge support. Although it has no extra component reinforcing its edges, they don't compress easily and won't sink very much when you sit or sleep on the side of the bed.
