Lower Back Pain

If you are a side sleeper, I highly recommend you don't get the Primer Copper. It's cause me so much shoulder/lower back pain. Unfortunately, I am out of scope and passed my year mark. I would have switched my mattress to Ultra Memory foam. Now I have to find another company.

Nectar Copper mattress

Would have returned with 365 warranty but was 4 days late. Wen sleeping on mattress the edge feels concaved and s hard to turn towards center. Would not purchase again. I returned the hybrid for the copper and will not purchase a nectar again.

Not for heavy people

This mattress is horrible. We have had it less than a year and it is giving us nothing but an air mattress experience and so much neck and back pain. And talk about how hot it gets, absolutely miserable.

Super soft, but surface gets hot!

We bought this mattress to replace our old much firmer mattress. It is soft, for sure, almost too soft. My partner tosses and turns and I can feel every movement he makes. And if you sleep hot beware! The surface of this mattress gets hot!! Overall we are not very happy with it, unfortunately.

I need to return this mattress for a firmer one.

I need a firmer mattress as I've had health issues for the last five months. I have joint pain in various joints, and my hips, knees, and back are more serious. my daughter slept on my mattress for a week and ended up going to the same chiropractor I go to. She told me my mattress is softer than hers. I would like to return mine for a Nectar Ultra Memory Foam Mattress. I'm willing to pay an up charge.

Copper Mattress

We have had this mattress and adjustable base for around 8 months now. Both my lady and I do not sleep well, wake up with back pain, stiff joints. We are currently in the process of returning both, and are going back to purple mattress.

Great mattress for side & belly sleeper

I wouldn't say it's perfect, but it's darn close. I have had it now for a couple months. It's great for sleeping on the side and belly. I really like how when my wife get's out of bed it doesn't wake me up as I can't feel the mattress move. It does confirm nicely when sleeping on the side, but doesn't have that slow moving material you might be used to from tempurpedic, etc.
