Puffy Diamond Mattress Review – Test Lab Ratings

In our tests, the Puffy Diamond Mattress’ exceptional motion isolation stood out among hybrid models. Its thick, seven-layer comfort system absorbs virtually all vibrations, preventing them from traveling across the mattress surface. The bed’s pocketed coil core also helps it prevent motion transfer.

For sleepers who awaken easily when their partner changes positions, this strong motion isolation could be a selling point. Most individuals are unlikely to notice movement on the Puffy Diamond if their partner tosses and turns or gets up during the night.

Thanks to its thick comfort system and medium soft (4) feel, our testers found that the Puffy Diamond Mattress offers notable pressure relief. The alpaca wool and fiber layers cushion the surface, while the polyfoam, latex, and memory foam layers mold to the sleeper’s body to limit pressure buildup. Additionally, a layer of zoned polyfoam provides variable support for more targeted contouring.

Side sleepers under 230 pounds are particularly likely to benefit from the Puffy Diamond’s pressure relief. By redistributing their weight, the mattress reduces pressure buildup around their hips and shoulders, which is a frequent cause of discomfort for side sleepers.

Compared to other hybrid models, the Puffy Diamond Mattress regulates temperatures moderately well. Because of their breathable cores, hybrid models often remain at a neutral temperature throughout the night. The Puffy Diamond’s alpaca wool layer, perforated latex layer, and coil core encourage air circulation to reduce heat retention. However, the polyfoam and memory foam layers may hold some lingering body heat.

For most sleepers, the Puffy Diamond’s temperature regulation should more than suffice. However, hot sleepers may notice mild heat retention.

The Puffy Diamond Mattress lacks the edge support common in hybrid mattresses. Because its comfort system is quite thick, sleepers sink in deeply before reaching the support system. High-density foam wraps around the perimeter of the coil core for extra reinforcement, but our testers found that the comfort system’s significant compression may still create a sensation of instability.

Sleepers who share their bed with a partner could feel that this restricts the usable surface area since they’re likely to feel more secure closer to the center of the bed. Getting into or out of bed may also be more challenging if you feel unstable sitting along the perimeter.

Since the Puffy Diamond is a medium soft (4) model with a thick, conforming comfort system, our testers noted that it isn’t as easy to move on as most firmer hybrid models. Most sleepers sink in relatively deeply, impeding movement. The comfort system also retains a body impression for a moment when the sleeper moves, which may further inhibit position changes. While the coil core adds a bit of bounce, the plush comfort system limits the mattress’ overall responsiveness.

Sleepers who change positions frequently or experience mobility issues may feel like their motion is limited when sleeping on the Puffy Diamond.

Like any model that contains synthetic materials, the Puffy Diamond may emit off-gassing odors after you unpack it. Off-gassing occurs when a mattress releases volatile organic compounds (VOCs), which are a standard byproduct of manufacturing foam.

The Puffy Diamond’s hybrid design allows enough airflow to help any odors dissipate relatively quickly. Depending on how well-ventilated your room is, most smells should air out within 72 hours.
