Beautyrest Harmony Lux Carbon Medium Pillow Top vs Nectar Premier Copper: What Actually Differs

The Beautyrest Harmony Lux Carbon Medium Pillow Top is a hybrid build, while the Nectar Premier Copper is a memory foam — that single difference drives most of the cooling, motion, and feel decisions below. The Beautyrest Harmony Lux Carbon Medium Pillow Top stands 15.75" tall versus 13" for the Nectar Premier Copper — a 2.8" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. Both sit at roughly 5.5/10 on the firmness scale — a medium-firm feel — so neither one is the answer if you need a dramatically different support level. The single largest performance gap is in pressure relief: the Nectar Premier Copper rates noticeably higher than the Beautyrest Harmony Lux Carbon Medium Pillow Top, which is the deciding factor if that dimension is high on your list. On a Queen, the Beautyrest Harmony Lux Carbon Medium Pillow Top runs $1,149 versus $1,599 for the Nectar Premier Copper — roughly $450 (28%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about. Trial periods aren't symmetrical either: the Nectar Premier Copper ships with a 365-night sleep trial versus 100 nights for the Beautyrest Harmony Lux Carbon Medium Pillow Top, giving you a longer in-home runway to send it back if the feel doesn't land.

Which Is Better For Your Sleep Style?

Side sleepers
Nectar Premier Copper

Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.

Back sleepers
Nectar Premier Copper

Firmness of 6/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 5.5/10).

Stomach sleepers
Nectar Premier Copper

Firmer at 6/10 vs 5.5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.

Hot sleepers
Spec not available

Cooling rating not available for one or both mattresses — spec not available.

Heavier sleepers (230+ lb)
Nectar Premier Copper

better long-term durability — the two specs heavier sleepers should weight most.

Lighter sleepers (under 150 lb)
Beautyrest Harmony Lux Carbon Medium Pillow Top

Softer at 5.5/10 vs 6/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.

Couples / light sleepers
Either works

Motion isolation rated the same on both — neither has a transfer-disturbance edge.
