Sleep Number Air Mattress Replacement

[RParker24]

I have a Sleep Number Comfortaire R3 or R5 Bed in our 2020 DS 4081. One of the mattresses has a slow leak and we are looking to replace it.

The mattress has the numbers S 275 C-King*A and 121575L on the top. Any help with where we could find one would be appreciated. I have not had much help from Sleep Number and my online search yielded some S 275 E-275 models but not A 275 C-King*A.

Thanks much.

Welcome to the forum.

Hopefully someone will be able to help find the correct model Sleep Number mattress. Good luck.

Call Sleep Number customer service 888-484-9263.
They will be able to get you the correct bladder. Not sure of cost but have seen some post in neighborhood of $125-$150.

We had a 2011 MA and replaced the two air-mattress for each side. Ordered them from Select Comfort.

[Lenmar]

2016 MA needs a new KING mattress. I can ask Newmar for the Select Comfort mattress and pump or I can get a non-air mattress somewhere else.

I am asking if anyone has replaced their KING mattress? If so, what can anyone recommend and where did you purchase it?



Thanks for any recommendation.

S275 and 121575L is the air bladder #
L means left side
Do your bladder’s zip together ?
You can find these on EBay New or Used
Cheaper than going to sleep number directly
Also sleep number does not make the Rv mattresses anymore
We have 2 beds in our house and 1 in the coach, all purchased off EBay
Also have a r5 queen that’s barely used for Rv
Can’t sleep on a regular mattress anymore
Been extremely happy with our beds

I have an SN RV king mattress that could be available. Phoenix area.

[RParker24]

Does your SN air mattress have any model or part number imprinted on the top?

Based on prior messages my number 'S 275 C-King*A' and '121575L' indicates that I have a California King, left side. Believe that it was a ComfortAire R3 or R5 bed. It zips to the right side air bladder and has one air nozzle.

Thanks,

Rick

We have the i10 model (queen sized) and after the 2nd air chamber we decided to just use that fix my sleep number bed website. They automatically fill it up every xx minutes so it keeps the bed at your pressure while you sleep. I just login to the website in the morning and turn it off, and at night I put it back on. It's easy. I had back surgery and the bed is really the only thing I can sleep on, but there will be pigs flying around my airstream before I pay them another penny for an air chamber. Just realized this is from January :(
