About
What it is.
Nectar positions the Premier Copper within its mattress lineup as a memory foam bed built around copper-infused layers, a material choice aimed at temperature regulation and freshness rather than pure novelty. It comes in the standard run of sizes — Twin XL, Full, Queen, King, and California King — so it fits typical bedroom setups without special ordering.
As a Nectar product, it's built for the ship-to-door mattress model: unbox, unroll, and use, with no showroom visit required. It suits buyers who want a widely adopted, low-risk choice rather than a niche or boutique construction, and who expect consistent quality across every layer of the bed rather than a single standout feature.
The verdict
The Nectar Premier Copper ranks seventh among cooling mattresses, backed by 4.3/5 stars from over 18,000 buyers who praise its comfort and assembly ease, though some report dimensional shrinkage and material degradation with extended use.

For you if
Look elsewhere if
You need a mattress that arrives ready to use with minimal fuss.
High assembly and ease-of-setup rating indicates straightforward unboxing and setup; memory foam requires no configuration or tuning.
You want a proven, low-risk mattress backed by broad buyer consensus.
18k+ ratings with 4.3/5 average and established Nectar brand signal maturity and settled product; copper-foam is a proven category.
You demand top-tier quality with no compromises on any front.
High comfort, support, and durability ratings with 18k+ reviews show strength, but low long-term material integrity and mid fit-dimensions signal unresolved weak points.
You seek a flagship mattress from an established, respected maker.
Nectar is a recognized brand with solid positioning, but lacks the prestige heritage or design cachet of true luxury mattress flagships.
You love mattresses that feel luxurious and deliver a sensory experience.
Copper-infused memory foam offers tactile appeal and cooling promise, but data shows no passionate design or aesthetic following beyond functional comfort.
You want a well-reviewed mattress without overpaying for brand prestige.
Mid-to-high street price with strong 4.3/5 rating covers essentials well, but cheaper rivals like Bear Original deliver similar comfort at half the cost.

Frequently asked
What buyers want to know.
Is the Nectar Premier Copper actually comfortable?
Buyers rate comfort and support at 4.7 out of 5, and many report it relieves back pain and keeps them sleeping longer than expected. Owners say it hugs the body well and outperforms other mattresses they've tried over decades.
How easy is it to set up?
Buyers give assembly and ease of setup a 4.6 rating. The mattress arrives compressed, unrolls on its own, and requires no tuning or configuration—it's ready to sleep on once fully expanded, which takes about a day.
Will the mattress stay the right size over time?
Long-term owners report dimensional shrinkage, with some finding the mattress narrows by up to 2 inches at the sides after time. Buyers also rate long-term material integrity at only 3 out of 5, suggesting some degradation occurs with extended use.
Who should buy this mattress?
It suits buyers who want a ready-to-use mattress with minimal setup and prefer a proven, widely-owned choice backed by broad buyer consensus rather than a niche option. It ranks fourth for side sleepers and eleventh for cooling mattresses.
What's the weak spot?
Build quality and durability rate 4.2, but fit and dimensions come in at 3.5—some buyers experience the shrinkage issue. If your mattress-to-frame fit is critical, the dimensional inconsistency is a real drawback.
Does the copper cooling actually work?
The material includes copper-infused foam meant for temperature regulation, and the product ranks among cooling mattresses. However, the grounding does not isolate specific buyer feedback on whether cooling performance matches the claim.
