  1. BOY, OH BOY, OH BOYD! GREAT NIGHT AIR SLEEP! review by DRSAMURI on 10/20/2017

    As a physician, I used to recommend stiff, firm mattresses for low back pain. Clinical studies now validate that firm is not suitable for most. The separate adjustability of the lumbar section is ideal for exacerbations of low back pain to achieve comfort and all important rest. I was amazed after my first night on my Night Air Ultra 6640. My back absolutely felt the best it had in years. The split King is a marriage saver as I prefer a more firm comfort versus my wife who prefers more plush comfort level.
    I am recommending the Boyd Night Air to both patients and colleagues. My only negative comment is that it is not Made in the USA.

  2. Just What the Doctor Ordered review by LARRY on 5/3/2017

    Prior to ordering I had back surgery and the support needed to alleviate residual pain was only possible by using pillows to support my back until pain receded and I could sleep. With this bed I only need to adjust the lumbar region until pain subsides. Works every time and I sleep better now than I ever have. This is a great mattress!

  3. A product that does what it claimed to do. review by Don on 4/13/2017

    We love our new bed! We have recommended it to all our friends. It has helped us both so much to get a good full nights sleep for the first time in a long time. We tried other beds at the big box stores and did not find one that would meet both of our needs. So thankful that we found Boyd Night Air.

  4. Awesome Bed review by Paul in CT on 4/3/2017

    This bed is the most comfortable one I have ever owned. Prior to buying it, I woke every morning with a sore back. Now I have the most comfortable nights ever. My only comment to Boyd is that I wish their directions for set-up were a little more detailed. The price of their beds are way lower than Sleep Number Beds and from what I gather from reading reviews on both companies, people seem happier with the Boyd products.

  5. So Far So Good review by Frank on 3/30/2017

    After a three week delay we finally set the bed in place. Getting use to it took a while, ie, setting it to our individual comfort level but I think we're about right. I believe we will know more in a few more weeks. The bed was easy to set up. We got a bit "rattled" seeing all the boxes but if you follow the directions it all goes together quite easily. So far we like it.

  6. Better than my Sleep Number bed review by Michael on 3/29/2017

    Have had the bed now for about 4 months, and both my wife and I found this bed to be better than our 5 year old Sleep Number bed. When we went shopping, the primary reason for us to get this bed was because we wanted a Split King, but when looking at the price of this bed vs. a comparable Sleep Number, we were saving almost 50%. And the bases were less expensive as well.

    When we got the bed, it was easy to assemble and set up. The bed is very comfortable, and easy to adjust. The corded remotes are nice in that they never get lost (happened a couple times with the cordless one for our other bed.)

    Only two (very minor) concerns... The remotes seem to always be "on". Have not been able to turn the lighted buttons off. And as we planned to use this on an adjustable platform, the instructions told us there was a pocket for a hook to attach the bottom of the mattress to the frame to keep the bed pulled down to the frame when it is in a reclined position. Ours do not have the pockets, but this has not been an issue when we sit on the bed. Our weight pushes the mattress into position.

    We did have one warranty item, and the response was very quick and the fix was easy. No concerns.

    Overall, highly recommended. When in the market again, we will definitely be back.

  7. Very good mattress, good price review by Bedtime on 3/29/2017

    I bought this to replace a softside waterbed we'd had for years. I loved the waterbed but after 2 leaks my husband had enough. Also, the need to drain it and the weight when we needed to move it were more and more of a problem as we got older. I bought the split king Ultra airbed. First, I should say that because the individual parts are light, I (57yr old, 5ft female) could get it up to our 2nd floor and set it up completely by myself. The individual controls are nice. Once dialed to your personal setting it is very comfortable. I experience no neck, back or hip pain which is an issue with most other beds. I get hot at night. This bed is definitely not as hot as memory foam but still hotter than the waterbed. I don't think there is any alternative that would be better though. So far, both my husband and I use the same firmness for the head/foot and lumbar chambers so a two chamber would have been fine for us.

    One of the mattress inserts had a leak when we received it but a replacement was shipped as soon as I called.

  8. Great Bed that needs minor improvements review by St Louis on 1/27/2017

    As another reviewer mentioned, the 6 chamber split king is a little misleading. As the head and foot chambers do NOT operate independently. I do like the lumbar portion operating on its own. Also, my wife likes very low pressure (soft bed) which causes problems for the remote. It gets confused and thinks it is full. I need to cycle the remote from fill to memory and back a couple of times to get it to pump air into it. I plan on calling tech support to see if it is a remote or sensor problem that may need to be replace. With this all said, I have never slept better in my life. We also purchased adjustable bases for each side of the bed, which really adds to the comfort. The vibrating mode rocks me to sleep every night. :-)

    I am giving 4 stars because of head and foot chambers do not operate independently and the remotes do not work quite right. But still a great bed and compared to Sleep Number and great value. We did not buy the adjustable bases from Night Air Beds. We purchased them at a local furniture store.

  9. Love the bed review by Louise on 1/26/2017

    This is the first bed that my husband and I agree is great! We had another brand of airbed before and this is far superior. The support and softness combination is unbeatable.

  10. Just what we needed review by Darrin & Gina on 1/13/2017

    We LOVE our bed! We've had it over a year now and have spent the year waking up without back pain! The best feature is the ability to adjust the middle support area. I'm a side sleeper and the pressure on my hips and then eventual sagging of a traditional mattress in the middle would cause back pain in the lower back area. In addition, my shoulder/neck area would ache from the pressure on it night after night. For side sleepers, lowering the pressure in the top to accomodate for your shoulder and raising the pressure in the middle to support hips is amazing! Having the ability to raise the head area has done wonders for sinus/allergies. I never wake up with headaches anymore....Just worth every penny. Had a problem with one of my air "bladders" within the first few months (wasn't holding air) and a simple phone call to the company led to the new "bladder" being sent. Very easy to swap out. Hubby is a back sleeper and snores...snoring is generally non existent with the ability to raise the top! Oh, and the massage feature helps in "lulling" you to sleep....Will buy this bed again and considering buying for guest rooms...
