Exclusive CertiPUR-US®, Foam "Perimeter Support" Design
Exclusive  CertiPUR-US®, Foam "Perimeter Support" Design

With the use of our Air Bed Components, our exclusive, 1.8 lb. Density, CertiPUR-US® approved foam, rail design, prevents the bed from bowing out on the sides. CertiPUR-US® certified foam products are "simply better for you and better for the environment". Some other manufacturers' rails use nothing or Velcro at the corners or with Sleep Number®, only lock in the corner (think "Lincoln Logs")or sat in plastic elbows. Both our head and foot rails are connected with a very thin, non stretchable cloth as are our 2 side rails connected, with the same thin layer of, non stretchable, nylon cloth, forming a non rigid box, inside of our air beds. Our "Perimeter Support, Sling Rail Design" will not allow the air chambers to bulge out (no bowing) and keeps the air chambers tight, so there is no "Gap" or "Hole" down the middle of our Air Beds. There is NO NEED FOR A CENTER FOAM "WALL" INSERT. Our "Perimeter Support, Sling Rail" System also helps gives our customers a much better edge to sit on, that does not sag/bow out and break down, when sat on, year after year. They also make assembly much easier! Again, this "Perimeter Support" rail system is designed for the specialized components offered in all of our Air Beds and may not supply the above, described results, with other Air Bed Components. The Rail Systems are considered "Special Orders" and may take longer for delivery, than our normal parts delivery.

Fabulous Bed Rails, Refurbish Your Sleep Number Bed!

- 26th March 2017

I received the bed rails for my queen sleep number bed repair today. I am thrilled! I installed them with no problem and after I reassembled and made the bed up I decided I needed a break and so I laid down on the refurbished bed and it was a moment of bliss. The bed has never had this much support or side sitting comfort. I will recommend to anyone these replacement rails and know I have helped someone.

What we think or what we believe is, in the end, of little consequence. The only thing of consequence is what we do.

Tired of a Droopy Bed

- 03rd April 2016

I recently bought your "Sling Rail" Perimeter Support System and the design really seems to be doing as advertised. I can now sit on my bed and not feel like I am going to fall off. At my age that is very comforting!

Thanks Again,

Better than the Competition!

- 30th January 2016

I have an older bed that was made by the competition. I have had to replace my side rails numerous times, because that are not held tightly together. I have had this system for about 6 months and it is holding up like new.

Much Better Rails Than Select Comfort

- 26th December 2014

My husband can be considered "Husky". We got tired of replacing the rails in our Sleep Number Beds. We first bought a "Perimeter Support" from Air Beds Unlimited for his bed and it works great. Now we are buying one for my bed. Much Better Construction!

They do work!

- 22nd December 2014

When I first read about Sling Rails, Perimeter Support System, I didn't understand the concept. After getting my Series 9 Diamond Air Bed, it became perfectly clear. The rails really do hold the air bed tightly together and there is no bulging on the sides. I can also sit on the edge of the bed. This is a sound technology!
