    • Fixed My Sleep Number!
Material Type: Cotton Size: King
Have a SN 20+ years. My side (of course) of the bed started losing air and then not level. Next a bulge in the middle. Need my SN but cost of replacement is expensive. Choice of this REM or $100 more for the OEM from SN's site. Will not buy a used mattress. The design is different from the OEM's and was a small concern. Swapped with defective bladder. Replaced the quick-connect connector on the SN's hose with the newly supplied connector. Attached the hose ends. Pumped to 50% then rezipped bed covers back. After making bed completely, pumped up to 80%. Mattress is holding air and flat and solid! Took a total of 15min to complete the replacement. ZERO difference from OEM mattress. Need a firm mattress and now I'm back in business!! SO nice to sleep again (2nd night on new). The new mattress is as "beefy" as the OEM. All materials look to be of upper quality and mattress is rock solid after 80% full. VERY pleased with purchase. Not sure if it will last another 20 years but as of now, perfect replacement for sleep number traditional air chamber. Very pleased with purchase. Received in perfect condition and item works perfectly. Thanks again. ... show more

    • Life Saving
Material Type: Cotton Size: King
My husband and I have two sleep number beds; one in our master bedroom, and one in our fifth wheel camper. They’re super comfortable, and we love them, but sleep number customer service has left so much to be desired. This is now the second time Silver Fish/REM Air has saved me from extreme aggravation. Last fall, we moved, and during the move, one of the quick connect clips on our air hoses broke, making our mattress useless. I immediately called SN customer service, explained that the only thing broken was the $0.2 piece of grey plastic in the quick connect clip, and asked them to overnight the replacement. They say they can’t just send me the clip, but have to send me the entire hose setup. Ok, fine. First email has it shipping to the wrong address, and that gets fixed. In the meantime, we ordered connectors from Silver Fish, fearing the worst from SN. We get the parts from Silver Fish, two-day Prime, and it works perfectly, and we’re back to sleeping like babies in our bed. A couple weeks later, we get the “replacement” from SN, only to find that they’ve sent us a brand new pump, which in no way addresses our issue. I didn’t even bother calling back after this... we just swapped out the pumps, and returned the “defective” old one that we really had no issue at all with. Now the R5 mattress we have in our camper is losing air in one air chamber only, and I’m able to determine that the air leak is directly from the rubber seal around the hose, so I call SN trying to get the replacement chamber. They’ve given me the run around because I bought their product, which they allow camping world to sell, and they have no record of my purchase. I’ve emailed the receipt from camping world three times, as they requested, but somehow they can’t find it. Needless to say, I’m again frustrated with their terrible customer service, and wound up turning to a Silver Fish for a replacement. This mattress is a touch shorter than the original air chamber for my R5, which I now realize is because SN uses a Cal King chamber in their R5, not a regular king. I honestly think that’s part of the problem since the longer chamber forces the hose connection against the headboard In the camper, and I believe that tight squeeze is what caused the leak in the first place. I put an old towel in the end to fill the mattress cover, and this also protects the connection point in my REM air chamber, so hopefully I won’t run into the same issue. This air chamber doesn’t have the zipper to connect it to the other side, and prevent any separation, but it holds the air, and that’s really what I needed. My bed required a male end on the mattress end of the hose, but I happened to have one laying around from the spare parts we ordered for our home mattress, so we were able to swap that out no trouble. Silver Fish did follow up and offer the part, though, which was really nice. I’m still going to call SN back and hassle them to give me my replacement, but as we are going on a trip and needed the part quickly, this was an excellent alternative. Thanks for the excellent customer service, and quality replacement parts! ... show more

    • Far superior air chamber than the original, how it should have been made.
Material Type: Cotton Size: Split Queen
So happy with this purchase, no more flat bed problems. Sleep quality is much better now that the mattress doesn't go flat and I have to wait for it to refill with air again. As soft or as firm as you want and no air loss! This air chamber is of a much, much higher quality than the original Sleep Number. Weight alone tells you that as it is about 3x as heavy. Material is super thick and not thin like the Sleep number. Well worth the money spent. As far as installation, it was a breeze. Flip the mattress over, unzip the cover, unzip the side that is bad (queen), replace, attach adapter to new hose, partially fill, zip everything up, and flip back over. The new hose is not on the side and at the top or bottom whichever you choose. Mine is at the top and I made a slit in the cover to accommodate the new location of the hose. Sleep Number does have a warranty on the air chamber, but not for the house call troubleshooting. To me, this was a more economical route and I received a far superior air chamber. ... show more

    • Mostly fixed my side of the bed
Material Type: Cotton Size: Split Queen
We have a 15 year old sleep number bed with 2 air chambers. My side had started seriously leaking. It got to the point where I'd inflate it when I went to bed and by morning it felt like I was sleeping in a hammock. Rather than replace the whole mattress I decided to give this a try. I can say that it's mostly been good. This new air chamber is not an exact match for the original one that I removed...some of the extra material around the edges made the fit a tiny bit larger than the old one. But it still went in with no issues. Main downside so far is that it still leaks just a tiny bit. And I do mean TINY. Maybe once a week I'll have to inflate the mattress again just a few points. (the screens on our remotes have long since died so I'm not sure how much exactly). Overall, I'm happy with it. It's kind of an expensive gamble but still a whole lot cheaper than a new mattress. ... show more

    • This item was perfectly flawless.... Wonderful Product
Material Type: Cotton Size: King
This item was perfectly flawless.... The mattress fabric feels at least twice as thick as the original mattress and it fit perfectly. No Issues. The hose and connection kit that is included was so ridiculously east to install. Just a note, one of the hose connectors belongs on the bed side of the hose and the other on the pump side. It would work just fine if they are reversed but if I understand correctly the correct bed side connector stops air from getting out of the mattress if the hose is disconnected. I'd recommend this product and I would absolutely buy it again if I ever needed to. I truly don't know what they could have done better. Keep in mind some beds and models may have different hose sizes that may need an adapter from a hardware store but it fit mine perfectly. Totally Satisfied !! ... show more

Receiving a personal phone call from a company is almost unheard of today. Excellent job, Tyler, and thank you! Everything seems to be working fine. I highly recommend this company and am looking forward to any new products they may have in the future.

    • Better replacement than the SN mattress
Material Type: Cotton Size: Queen
Exact fit as measured, easy connection conversion to better air hose connectors. Despite labeled as Plush, pumped up to 70 this mattress is comfortable and properly firm.
