A Better Sleep Experience

Sleep cooler with our 12" Copper Infused Memory Foam Mattress. By infusing the foam with copper, it provides a source of conductivity to dissipate heat as you sleep. With our multi-layered mattress, the sleep surface reduces pressure on critical areas of the body, including hips and shoulders, to prevent tossing and turning throughout the night. Our team of bedding experts set out to create a quality mattress with some of the most advanced technologies to provide you with a better, cooler sleep as well as develop a mattress that bends better with adjustable bases to give you the ultimate sleep system.  The mattress is covered in a soft, breathable cover that is zippered and machine washable.  The Air Grid™ Base Foam provides breathability and flexibility when paired with an adjustable base.

Not firm

There is no firmness to this mattress at all, will sink in and be uncomfortable if you're a big person who needs firm support. Other than that, it's perfectly fine.

It's been great so far!

We have only had the mattress for a little over a week. But so far, it is much more comfortable than our previous mattresses.

What a bed! 🤩

Both my husband and I love this bed. We had a high end adjustable queen, but the flex/split head king fixed our issue with wanting individual adjustments. The waterproof mattress cover is a must-we got two. I did have to contact blissfulnights about the length of the split (36”) in order to purchase the correct sheets. Our old bed had an app that communicated with a module under the frame to provide sleep information and tracking as well as automatic adjustments for snoring. I miss that and if blissfulnights ever makes a module that provides such a feature, I’d love to add it to my bed. Overall, this is a bed worth buying.

Comfort but a little short

The mattress as far as comfort is great but length wise its short. I am 5'7 and my feet touch at the end of the foot of the bed. Very strange. What would someone 6' ft tall do. Just strange. But very comfortable.

Nice bed

Ordered the mattress and the adjustable base. Still getting used to it, but so far so good. Mattress is comfortable, and once we figured things out the base seems to be working fine. Had a couple of hiccups at first due to unclear instructions, but a quick call got a quick and accurate answer. Seems lots of similar calls = reps well versed in the answer. So Blissful Nights, please review your product info/set up info and update as appropriate. Overall, we like the bed so far.

Best purchase ever!

We have been wanting an adjustable bed for a while but we’re hesitant to spend a fortune. We found the perfect solution with Blissful Nights split top king adjustable bed. The price was unbelievable and we are now getting the heat also. I would definitely recommend it to anyone who is looking for a better night’s sleep without breaking the bank.

We're very impressed with the split top king 12" copper mattress. It is very comfortable. Definitely worth the money. It's rare that my wife and I agree on a mattress. We both love it.

So far So Good

We have always had a pillow top mattress so when we first got on the 12" medium firm copper gel infused mattress it seemed a little firm. The longer you are on it the softer it feels. The big reason we tried it was the split head because of our new adjustable frames. We love that aspect but do miss the immediate softness feel of the pillow top. We have slept very well so likely plan to keep it. Really appreciate the ability to try before you buy with Blissful Nights!

Excellent mattress!

This mattress is literally the answer to my prayers. I previously had a mattress that was split into two twin mattress as part of the adjustable base. This made it difficult to sleep at night because the mattress constantly separated in the middle. This new mattress is only split at the top and is much more comfortable! I recommend it 100%!

So far it’s so perfect!! It’s pretty firm and it is easy to get out of in the morning. Just to have my head down and hubbies head up it really makes him snore less and I am comfortable more flat. The price was so much better than what we were finding in the stores. Great find

95% as good as sleep number for a fraction of the cost

My wife and I had decided we wanted an adjustable bed and we went to try some out. We both really liked the split head but unfortunately Sleep Number was the only one we could find. The total cost for the mattress and base was going to be around $10,000. I did some searching and found Blissful nights online. I was skeptical at first because there weren't many reviews and I couldn't tell if it was legit or not. I read the fine print, made sure I understood the return policy (there's different amounts of time for the base vs the mattress). Got out my amex (since I knew I'd be covered) and placed the order. We never received any tracking information but after about a week the parts started to arrive. I think we got 2-3 different deliveries. I assembled the bed with no issues and at first it seemed a little soft, the equivalent of about a sleep number of 20-30. I was bummed because we were really hoping for something medium/firm. I know memory foam takes some time to expand so we gave it a few days and after about a week it had really firmed up. I'd say it's equivalent to about a 50-60 on sleep number, which is exactly what we wanted. The bed is comfortable and my neck pain from sitting up on my phone has gone away. We've had this almost 3 months now and I couldn't be happier. We spent significantly less than we would've on sleep number and while this isn't adjustable in firmness, it's the right firmness for us and we get all of the other benefits. If you're debating giving this a try, I'd go for it.
