Sapphire Dream Mattress Review

The Sapphire Dream has above-average motion isolation thanks to three elements of its construction.

The topmost layer is made with memory foam, which has a well-known ability to cradle the body and minimize motion transfer. The soft feel of this memory foam along with the polyfoam beneath it enhances the sink of the mattress, decreasing the potential for vibrations to spread across the bed. The individually wrapped innerspring coils also curtail excess ripple effects from their springiness that could transfer motion.

The combined effect of these components gives the Sapphire Hybrid solid marks for motion isolation, allowing most people who share a bed to avoid unwanted awakenings from their partner’s movements.

The primary pressure relief offered by the Sapphire Dream comes from its memory foam top layer. Memory foam is able to compress in proportion to the body’s shape and weight, providing both a sense of hug and extra cushioning to pressure points. The innerspring coils give a light boost to this pressure relief because of their ability to react to how weight is distributed on the bed.

These components deliver a moderate amount of pressure relief, but the Sapphire Hybrid does not score higher in this category because the memory foam is only 1.5 inches thick, and the polyfoam beneath it does not offer the same level of tailoring to suit the body’s needs. With a thinner memory foam layer, the Sapphire Dream may be less apt to deliver needed cushioning for people with a higher body weight as well as people with particularly sharp pressure zones.

The Sapphire Dream hybrid rates as above-average for temperature control.

Although many people associate memory foam with sleeping hot, the memory foam layer in the Sapphire Dream is infused with graphite that is intended to limit how much heat the foam holds in during the night. The memory foam layer is also built with an egg-crate structure, creating more open space for air to pass through and carry away excess warmth. Ventilation is also a plus for the innerspring coils as air moves easily through them and dramatically cuts down on heat buildup in the bed’s support core. If someone does start to heat up, the Tencel material in the cover can help wick away moisture, dissipating heat through its breathable fabric.

Each of these parts of the Sapphire Dream improves its temperature regulation and makes it a quality option for people who tend to sleep hot.

Most sleepers find that the Sapphire Dream mattress provides solid edge support.

The driving force behind the bed’s edge support is the innerspring support core. In general, coils are better able to withstand weight at the edge without losing stability. That is enhanced even further in the Sapphire Dream because the coils around the perimeter of the mattress are lower gauge, which means that they are thicker and hold up better under weight. These thick, durable coils are made of high-grade steel that maintains its shape even when someone is sleeping or sitting near the perimeter of the mattress. The two foam layers in the pillow-top are considerably softer, and the sink from those materials will be noticeable when you’re on the edge of the Sapphire Dream mattress.

Overall, the mattress rates as above average for edge support, but it’s normal to detect some foam compression around the perimeter.

The thickest and largest part of the Sapphire Dream mattress is its support core, and the individually wrapped coils in that core generate enough springiness to make it easy to move on top of the bed. Although the foams in the comfort system give the mattress considerable hug and sink, the robust coils keep sleepers from sagging too far into the bed or feeling like they are stuck in place. The smoothness of the Tencel cover allows you to adjust your position in bed without undue friction between the mattress cover and your sheets. All together, these factors strengthen the performance of the Sapphire Dream in this category.

While the Sapphire Dream mattress is good for sex, it does not have a standout rating in this category. The reason for this is that some elements of the bed’s construction facilitate a vibrant sex life while others are not as conducive to sex.

On the positive side, the thick innerspring support core gives the bed sufficient bounce to enable most sexual activity. In addition, the coils offer sturdiness and stability during intimate moments, and the base polyfoam helps absorb sound from the movement of the coils.

On the negative side, the memory foam and polyfoam in the pillow-top have limited responsiveness, meaning they are slow to bounce back to their normal shape as you move on them. This means that some extra effort may be needed for quick movements on top of this mattress, but the Sapphire Dream’s construction rarely inhibits sex.

Off-gassing occurs when volatile organic compounds (VOCs), which are generated during mattress production, get released after the mattress is unboxed. Not all materials give off the same amount of VOCs; the highest amount usually comes from foam, including memory foam.

While the Sapphire Dream has foam components, they are not the thickest parts of the mattress, reducing the bed’s off-gassing. For this reason, few customers complain about odors or off-gassing from the Sapphire Dream, especially relative to other hybrid mattresses on the market.
