Disclaimer: This is my thoughts on my situation. Everyone’s situation may be different.
I recently reviewed my Nectar mattress. The tl;dr is that it was great in the beginning, but has heavily sagged since around the one year mark. I heavily regret not returning it. The issue is that this caused me to sleep in the mattress resulting in awful back pain. Cheap hotel beds felt a million times more comfortable than the sagging Nectar. As a result, I ordered a Sleep On Latex firm mattress topper (3 inch thickness) and it has been amazing!
I have been sleeping on my Nectar mattress with Sleep On Latex firm mattress topper for just over two weeks now. My daily back pain that I became accustomed to waking up to from the Nectar mattress is gone. That’s it! Worth every penny just for that. I’m hoping it will stay this way for at least a year. I spent $440 per year on Nectar ($1,000 and slept on it 2.25 years before almost throwing it away) so the Sleep On Latex mattress topper at $400 worked out. Fingers crossed.
If you are sleeping in your mattress causing you back pain I would definitely try a firm latex mattress topper and see if it works for you.
Edit 1: I realized I forgot to mention the cons. What you hear about Latex being heavy and smelly is true. It’s heavy as hell and hard to get on your bed. But once you do you’re set. It also smelled for me for 4-5 days but I think that’s because I used it right out of the box and did not air it out. I put on sheets a few hours after putting it on my mattress.
Edit 2: 5 month update. It works! This mattress topper saved my sleep. I was honestly so miserable and this completely fixed my back pain instantly. Now 5 months in it’s for sure lost some durability, but it still feels like 95%+ durability. This may not fix everyone’s issue, but if you are in a similar issue as me, I would highly recommend it as of now. Also there has been no smell for a long time. The smell is completely gone.
