Review: Perfect support for 40 yr old male 190 m b 5'10" - I've always tried these Tempurpedic like beds but I've never done anything but sunk inside of them. This is the cheapest model and it is amazing. I'm a side sleeper and before I would wake up with my hips hurting and my shoulders killing me. When you lay in it you sinking just enough for it's a mold around you but that's it it's not hard it's not soft it's definitely what Goldilocks would choose ! This bed is so comfortable I would buy it in a heartbeat if you're considering it.it is worth it!
Review: No Regerts! - I’m very pleased with the quality and price of this mattress! I tested dozens of mattresses in store (none Nectar) and found that of all the styles an all foam one worked best for me. Then it was a matter of finding one for less than $1k that still was good quality. The box was a little heavy but I was able to get the mattress out and onto the frame alone. Immediately after cutting the plastic off the mattress grew to almost its full size in less than 30 minutes but looked really lumpy on the sides and the corners didn’t fill out. 48 hours later and the corners are pretty much filled out and the bed has reached its final firmness level and doesn’t look lumpy at all. There was the slightest scent on the mattress immediately after opening but only when putting my nose on the mattress and it went away in minutes. I got the medium firm and it’s on the firmer side. I’m 200lbs and I don’t feel like I’m sinking into it but it’s still extremely comfortable and shapes to my body. The top layer feels cool to the touch but after putting sheets and blankets on you can’t feel anything. Overall for less than $1k I’d say it’s a great deal. Comfortable and sturdy, pretty much all you need.

### ⭐⭐⭐⭐⭐ Quality mattresses that are comfortable
*by D***N on January 14, 2026*

I bought two twin XL instead of a king so my wife and I didn't disturb each other when we roll over which helps you stay in a deeper REM cycle. They are very comfortable foam mattresses that hold their shape and bounce back. They are very supportive and you do not sink in or have hard spots on your lower back. I tested a lot of mattresses in stores and I honestly like these best and they were less expensive. Some were too hard, some too soft, these are just right. I prefer these over pillow tops which are susceptible to body impressions and hybrids which didn't feel as supportive to me.
