Great adjustable split King purchase
Split king bed was easy assembled. This is a good and stable base, it is a bit heavy even as two Twin XL. The mattress is decent, but I did purchase mattress topper for extra softness for my liking. Regular Twin XL sheets does fit well. I am sleeping much better now that I can change incline positions and the massage is a nice feature after a long day! It is a good vibration type of massage but is relaxing. I will recommend this bed for the price is well worth it. No complaints! Also, shipping was fast 😁

Excellent bed!!
Color: Black
Size: Split King
Set name: 14" Copper Mattress + M200
I was very skeptical about buying a bed online but after searching local stores this was the only affordable option for us. Husband is 10 years into Parkinson’s diagnosis and was needing help getting up at night. This bed has been a blessing!! Not only has it helped him get out of bed (when he remembers to use the remote) it has helped both our backs. I am 70 and he is 77 with several diagnosed back issues. We both wake with much less pain. Our previous mattress was only 3 years old and not a cheap one. These frames are amazingly sturdy and it was super easy to put together. There was no funny smell coming from the mattresses and my nose is quite sensitive so that is saying a lot. Very satisfied! Would buy again!!

This bed is perfect for us. The adjusting is so quiet you're not waking nobody if you're moving it up and down during the night. It is easy to put together. I would absolutely buy it again.

Customer service is on point!
Color: Black

Set name: 14" Charcoal Mattress + M200
The bed is absolutely! Mattress is firm. I had a bit of an issue with the bedframe as the remote would not sync up. The company sent me a brand new remote. And explained how to Pair the bed properly. They got back to me in a timely manner. Every time I had a question, and made me feel like they cared. I will definitely use them again. The only issue that I could find with the bed is that it does not have side rails to hold the mattress in place from left or right. But it does come with the foot rail, which keeps the mattress from sliding off the bed. Thanks guys. I really appreciate you.

Excellent!
Color: Black
Size: Twin XL
Set name: 12" Charcoal Mattress + M200
We bought twins of this product. We pushed them together to make a king size bed but each is dressed with twin linens so we can operate independently. I was so shocked at how great these beds are considering the price! The frame is unbelievably easy to put together, super sturdy and works perfectly. Coming from a really nice pillow top, I was a little concerned about the comfort of the mattress. However, they are unbelievably comfortable. I would definitely buy them again and I highly recommend them.

LOVE THIS BED! Comfortable, adjustable with easy controls for a disabled person. Made our lives so much easier! The matching mattress is very comfortable and easy to re-sheet. And the price is affordable, especially if you're renting a medical bed!

Adjustable Bed is a Must
Color: Black
Size: Twin XL
Set name: 10" Charcoal Mattress + M200
We purchased a Twin XL so a family member would have the options to adjust the head and foot areas as needed. The family member loves the bed and it has been beneficial when sleeping and also with leg/foot swelling post-surgery. He also said the mattress is very comfortable. Directions to assemble the bed frame were clear and easy to understand. Complete assembly (including putting the mattress on the frame) took 10-15 minutes. As far as the mattress, you simply remove it from the packing box and wrapping and let it inflate. Customer service is excellent. Their team members are quick to respond to your questions and needs.
