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!

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.

We’ve had this mattress out for almost 72 hours with 2 nights of sleep. Was not impressed. #1 our mattress never went to its full size. Each corner was dented in and it caused the middle to be much higher than the rest of the bed. 2. It advertised this mattress as a 6.5 between firmness and softness. We needed some sort of firmness so that I could breastfeed, yet be soft enough to be comfortable. I haven’t found firmness. After sitting (or applying too much pressure at pressure points of the body) I sink so far in that my MIDDLE BACK feels the mattress. This also makes it extremely hard to breastfeed. When trying to adjust, the baby sinks into the pressure spots (as I apply more pressure than she does due to adult vs child). Even after NUMEROUS pillows, there is just no support, especially since the mattress never evened out. 3. The last 2 nights of sleeping on this mattress, I’ve awaken with pain in one of my legs. (I have to sleep on my side to breastfeed and I alternate throughout the night). And the pain hasn’t died down. This mattress was advertised to ease pain, not cause it- but I’m having the opposite effect. Ultimately, we will be trying to return this ASAP. Update!: we decided to keep it a little longer and allow it to shape/form correctly. We placed it on an actual bed support and it was immediately a change for the better. I’m not sure if all the cushion on carpeted floor was the reason, but it was night & day after putting it on a platform bed. Super comfortable, and the movement doesn’t effect everyone sleeping in the bed. Reminds me of that wine commercial mattress. I haven’t done wine, but I’ve done a glass of water and it held place while I got off the bed. It hugs your body without making you feel like you’re sinking into the mattress. Super comfortable & the mattress shaped itself out in a few days after my initial review. No body pains, better sleep, and even my husband doesn’t snore as much or as loud when he does snore. Definitely such a difference from when he falls asleep on the couch watching tv. SO grateful we gave it time & kept it! Definitely a gem for a fraction of the cost of other mattresses. 💯

2nd Update: we have decided to return the mattress. We are so thankful for the 365 night trial. We feel this mattress may just be a bit too soft for us. While it’s extremely comfortable to feel like we are sleeping “in” the mattress, we don’t think it was ideal for my neck, shoulders, and back. So far Nectar customer service has been extremely helpful. I had to send photos of the mattress, then they sent someone to pick it up. Now, just waiting for a refund. They tell me it will take 10-15 days. They asked for my bank account info, which I wasn’t fond of, but hoping it will all turn out ok! UPDATE: I’m still sleeping very well and overall really like the mattress. I’m concerned it will wear out quickly though. We bought it in September and it’s now March and we had to rotate the mattress because I was getting very noticeable back and neck soreness every morning that was different than the original soreness I experienced. The mattress was noticeably more stiff when we rotated it, so we will see as time progresses if continuing to rotate it every few months will do the trick. I did a ton of research about mattresses. My husband and I are both primarily back sleepers, and he has some sciatic nerve pain. His nerve pain is now gone, and we are sleeping great. I love that I can barely feel when he moves! I’m dealing with a little bit of back and neck soreness but I think I have to figure out my pillow situation since I sink into this mattress more than my previous one. For reference, we are mid-30’s. I’m 175 lbs and my husband is 200 lbs. Also, be sure you pursue the free serenity sleep bundle! (Contact Nectar with your Amazon order info). The pillows are HEAVENLY.

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.
