Motion Isolation and Sharing a Bed
Q4. Does Beautyrest® Harmony Lux™ Diamond Mattress provide reasonable motion isolation when sharing a bed with others?
Beautyrest® Harmony Lux™ Diamond mattress scores above average in this category. Memory foam are known to isolate motion well. Memory foam of different types in different comfort layers helps to cut down on motion significantly; therefore, if you are sharing the bed with your partner, changing sides should not bother you or your partner much. Since pocketed coils are encased individually, they respond to any movement independently which minimizes motion transfer to a large extent. But the pocketed coils though are individually wrapped are responsive and do transfer little motion while getting in and out of bed. More memory foam in the comfort layers of the Pillow Top makes these mattresses better at isolating motion than the Classic Top.
Edge Support
Q5. How would you rate the edge support of Beautyrest® Harmony Lux™ Diamond Mattress?
Beautyrest® Harmony Lux™ Diamond mattress offers superior edge support. T2 pocketed coils make the mattress’s support system robust, preventing sinking and sagging along the edges. This makes sitting or lying near the edges feel safe. The ultra plush Pillow Top with more memory foam also does not compress under pressure, thus making all the models safe for sitting or lying near the edges.
Recommendation based on sleeping style
The Beautyrest® Harmony Lux™ Diamond mattresses have a wide selection of mattresses catering to the need of almost all types of sleepers as it has offerings from, medium to ultra plush.
- Side Sleepers: Side sleepers put pressure on their hips and shoulders; thus, these areas press against the mattress leading to pressure points. Hence side sleepers prefer a mattress that would cushion their pressure points without sinking deep into the bed. Plush models of the Classic and Pillow Top options will be a good choice for lightweight side sleepers. The foam layers would cushion the hips and shoulders, keeping the spine properly aligned, thus reducing pressure on the lower back. Those in the average-weight category can go for the medium-firm model and heavyweight individuals will need to explore other options.
- Back Sleepers: Sleeping on the back is the prime position to sleep, as it maintains the natural posture, keeping the spine appropriately aligned. Contouring and support are essential for back sleepers. Light weight back sleepers will love the comfort offered by the plush version of the Classic and ultra plush variant of Pillow Top mattress, while average weight back sleepers will get ample support and pressure relief from the medium-firm versions. T2 Pocketed Coil® in the support core prevent the hips from sinking, keeping the spine aligned. Heavyweight sleepers will not get adequate support, contouring, and firmness sleeping on the Beautyrest® Harmony Lux™ Diamond mattress.
- Stomach Sleepers: Stomach sleepers need a firm, supportive mattress to keep their hips and abdomen from sinking deep into the bed. Light and average-weight stomach sleepers may find some comfort with the medium models of the Classic and Pillow Top but those above 230 pounds will need to explore other options from the Beautyrest catalog.
- Combination Sleepers: Combination sleepers keep changing positions; thus, they need a good, responsive mattress. With medium and plush firmness, the Beautyrest® Harmony Lux™ Diamond may be a good choice for combination sleepers of light and average weight, however large sized individuals will not find comfort sleeping on the Diamond. Pocketed coils in each mattress support the body in most of the sleeping positions.
