Save $500 to $1,500 vs. OEM
REM pumps start at $250. Sleep Number charges $700 or more for the same repair, plus a service fee. Keep the bed you already paid for.
Fits Sleep Number and Select Comfort
Every aftermarket air bed pump in the REM lineup connects to the standard 3/8-inch ID valve. No adapters needed for most beds built after 2005.
Whisper Quiet Motor
Noise-reduction technology keeps the pump barely audible during inflation cycles. One reviewer thought the unit was off the first time it ran.
Lifetime Manufacturer Warranty
Silver Fish International backs every pump with a no-expiration, no-prorate warranty. Eight years in, one verified buyer purchased the same model again for a second bedroom.
Installed in 15 Minutes
Cut your old hoses, snap on the quick-lock connectors, plug in the power cord. Scissors handle the only cut. No plumber, no electrician.
Pumps, Chambers, Hoses, and Fittings
Four pump models, a vulcanized air chamber, a 5-foot replacement hose, and a barb reducer cover every part that wears out in a Sleep Number bed.
Four Steps to a Working Bed Again
Identify Your Setup
Count the hoses running from your current pump. Two hoses mean a standard dual-chamber bed. Four hoses mean a zoned mattress. Measure the inner diameter: 3/8 inch or 1/2 inch.
Choose Your Pump
Pick wired ($250, two remotes) or wireless ($279 to $325, one or two remotes). Zoned beds need the 4-valve model at $289. All models use the same Whisper Quiet motor.
Swap in 15 Minutes
Cut the old hoses off your dead pump with scissors. Push each hose onto the quick-lock connector until it clicks. Plug the power cord into any wall outlet.
Dial In Your Firmness
Press auto-fill on the remote. The pump inflates each chamber to a default level. Adjust left and right sides independently. Save your presets for the next night.
Built for the Parts That Fail First
Sleep Through the Night Without Hearing the Pump Cycle
A partner adjusts their side at 2 a.m. The motor spins up, holds pressure, and shuts off. You stay asleep. REM pumps use a noise-reduction motor that runs quieter than the OEM units shipped with beds from 2012 to 2016. Reviewers describe the sound as barely audible from across the room.
- Noise-reduction motor runs below conversational volume during a full inflate-deflate cycle
- Compact 10.25 x 6 x 4 inch housing tucks flat under a standard bed frame with clearance to spare
- One Amazon reviewer wrote the pump was so quiet they checked twice to confirm it was running
Stop Replacing the Entire Bladder Every Time a Seam Splits
Factory air chambers bond two sheets of vinyl along a heat-sealed seam. After five to eight years, that seam cracks. Air escapes. You sink into the bed frame by morning. The REM chamber eliminates seams entirely through vulcanized construction. A single continuous wall holds 400 lbs on the Eastern King size without a weak point.
- Vulcanized walls replace heat-sealed seams, removing the most common failure point in original bladders
- 400 lb capacity on a 72 x 34 x 6 inch Eastern King bladder supports two adults plus shifting weight
- Cotton and natural latex outer layer stays cool against the mattress cover after eight hours of body heat
Set Each Side of the Bed from One Wireless Remote
You sleep firm. Your partner sleeps soft. The REM wireless remote controls both chambers from a single handset. A backlit digital display shows the current level for each side. Press left or right, scroll to your preset, and the pump adjusts only that chamber. No cables run across the floor.
- Single ergonomic remote stores independent presets for left and right bed chambers
- Backlit LCD digits stay readable in a dark bedroom without turning on a lamp
- One-button auto-fill inflates to your saved firmness level in under 90 seconds per side
Run a Zoned Mattress on Four Independent Channels
Zoned air beds split each side into head and lumbar sections. Standard 2-valve pumps cannot address all four zones. The REM 4-valve wireless pump routes pressure through four separate hoses, each feeding its own chamber section. Two wireless remotes control all four channels independently.
- Four-valve design feeds head and lumbar zones separately on each side of a dual-chamber bed
- Ships with four 5-foot hoses and two wireless remotes, enough hardware to connect without add-ons
- Backward-compatible with standard single-chamber beds by capping unused valves
About REM Air System
Silver Fish International, LLC launched the REM Air System line to solve a specific problem: Sleep Number and Select Comfort owners faced $700-plus repair bills when a single pump failed inside a $3,000 bed.
The company designed a Select Comfort compatible air pump replacement that matches the original 3/8-inch hose fitting, fits under the same bed frame, and costs a quarter of the OEM price. Four pump models cover wired, wireless, and 4-valve configurations. A vulcanized air chamber, a 5-foot replacement hose, and a barb reducer round out the catalog.
One verified Amazon buyer installed the first-generation REM wired pump in 2016. Eight years and roughly 2,900 nights later, the same unit still held pressure. That buyer purchased a second REM pump for the guest room.
Today the product line carries over 3,400 combined Amazon reviews with a weighted average above 4.5 stars. Every pump ships with a lifetime manufacturer warranty from Silver Fish International's U.S.-based support team.
What Customers Say
I rarely write reviews, but the quality of this product and the return on investment made me share. We had our air bed for approximately 8 years and dreaded spending $1,100 on a Sleep Number replacement pump. This REM wireless pump installed in 10 minutes. The noise is practically nonexistent compared to the old unit. My wife adjusted her side at 3 a.m. last Tuesday and I slept through the entire cycle. Save your money and go with REM.
Awesome alternative to the manufacturer's pump. Very easy to install. We purchased our Select Comfort mattress in 1997 and this pump works perfectly. Wired remotes are nice, easy to use, and no worries about batteries dying. The bed feels exactly like it did with the original pump. Took me about 12 minutes from opening the box to sleeping on a fully inflated mattress. Cannot beat the lifetime warranty at this price point.
My Sleep Number air pump failed years ago on one side of our queen size bed. I tried to repair it myself but had no luck. A replacement from Sleep Number ran nearly 400 dollars. I found this 4-valve pump on Amazon and took the chance. It fit perfectly. Both sides hold pressure overnight. The wireless remotes are responsive and the backlit display reads clearly in a dark room. Three months in and zero complaints.
Air mattress fit our Sleep Number king bed. Hook up was easy. Inflation was a breeze. Air tight, no leaks. The vulcanized construction feels significantly more durable than the original chamber that split along its seam after six years. I measured the new bladder before installation and it matched the spec sheet exactly: 72 by 34 by 6 inches. Filled it to full firmness and the bed sat level across both sides.
Got this pump for my old California King Sleep Number. One side kept losing air and killing my back. Went to the Sleep Number store and the quote was $1,500 just for parts and labor. This REM wireless unit solved the problem completely. The remote lets me set each side independently. My wife runs soft at around 35, I run firm at 75. Neither side loses pressure overnight anymore. Should have bought this two years ago.
We have an old 4000 Model Sleep Number bed in a spare room. I love it, but spending $1,500 to replace an extra bed made no sense. When the mattress started leaking and the old pump died, I bought both the REM replacement hose and the wired pump. The hose connected cleanly with the quick-lock fitting. I reused my original connector on the opposite end. Total repair cost: $279 for both parts. The bed works better than it has in a decade.
The pump went out on our Sleep Number bed and this fixed the issue regarding air levels. Relatively easy to install if you can fit under your bed. It does not have the vibration feature which according to reviews the last few years of Sleep Number pump models did not either. Both wireless remotes work well. The digital display is bright enough to read in a pitch dark room. Solid purchase for the price.
My old sleep number EFCS4-2 pump died, so after reading the reviews I decided to try one of these. The install was easy and straightforward. I cut the hoses off my old pump as close to the connectors as possible and had enough extra to attach the quick-lock fittings. Took fifteen minutes total. The pump runs quieter than the original. Both sides hold air through the night. For $250 with a lifetime warranty, this is the best value in the category.

What Happens After You Order
Unbox and Install
Unbox the pump, snap the quick-lock connectors onto your existing hoses, and plug in the power cord. Sleep on your preferred firmness setting tonight.
Dial In Your Presets
Fine-tune left and right sides independently each night. The remote stores your presets. Most owners settle on a final number within five sessions.
Zero Midnight Air Loss
No midnight air loss. No top-ups. The vulcanized chamber holds steady pressure through seasonal temperature swings that shift air density.
Lifetime Warranty Kicks In
Lifetime warranty activates on any motor or housing failure. One reviewer ran the identical pump for eight consecutive years before ordering a replacement.
Problems REM Air System Solves
Sleep Number quoted $1,200 to replace your pump
OEM replacement pumps start around $400 before the service call. Add labor and you cross $700 easily. The bed frame, mattress cover, and air chambers still work fine. Throwing everything away wastes a $3,000 investment over one failed component.
You wake up sinking into the bed frame at 3 a.m.
The pump stopped holding pressure overnight. One side deflates while the other stays firm. You spend ten minutes re-inflating before falling back asleep. A failing pump motor cannot maintain the seal against slow leaks in aging hoses.
The bladder split along its factory seam
Original air chambers bond two vinyl sheets with a heat-sealed seam. After five to eight years of nightly pressure cycles, that seam cracks. A slow leak turns into a flat side within a week. The REM vulcanized chamber eliminates seams entirely.
You ordered the wrong hose size and nothing connects
Sleep Number beds use 3/8-inch ID hoses. Older Select Comfort models use 1/2-inch. Mixing the two means a pump that runs but cannot inflate. The REM barb reducer ($15, pack of 2) adapts 1/2-inch hoses down to the 3/8-inch standard.
The pump wakes your partner every time it cycles
OEM pumps from 2012 to 2016 run noticeably louder than newer models. Every firmness adjustment forces a choice between comfort and silence. REM Whisper Quiet motors cut that noise below conversational volume.
Expert Take
"Most people replace an entire Sleep Number bed when only the pump fails. That decision throws away a perfectly good frame, cover, and foam layer. Aftermarket pumps from brands like REM Air System match the OEM hose diameter, firmness range, and chamber compatibility at a fraction of the price. The lifetime warranty matters more than the sticker: it means the manufacturer expects the motor to outlast the mattress around it."
- Count your hoses before ordering. Two-hose beds use the standard 2-valve pump. Zoned mattresses need the 4-valve model at $289.
- Keep your original hoses if they bend without cracking. The REM pump accepts them through the quick-lock connector. Save $29.
- Set each side 5 numbers apart for the first week. Pressure preferences shift as the new chamber breaks in and the foam settles.
Who Buys REM Air System Parts
Sleep Number Owners with a Dead Pump
Your bed cost $2,500 to $5,000. The pump failed after warranty. Sleep Number quoted $700 or more to fix it. You need an exact-fit replacement at a price that does not punish you for keeping the same bed.
RV and Guest-Room Owners
You run a Select Comfort mattress in a motorhome or a spare bedroom. The compact REM pump tucks behind the headboard. It handles seasonal disuse, road vibration, and temperature swings without losing calibration.
Couples Who Sleep at Different Firmness Levels
One side soft after a long day. The other firm for lower-back support. The wireless remote adjusts each chamber independently. Neither person rolls toward the middle or wakes the other.
DIY Homeowners Who Fix Instead of Call
You replaced the garbage disposal last spring. A 15-minute pump swap with quick-lock connectors and a pair of scissors fits your skill set and your Saturday morning.
Not the right fit: Sleep Number 360 Smart Bed owners. The 360 uses a proprietary SleepIQ pump with integrated sensors. REM Air System fits traditional (non-smart) Sleep Number and Select Comfort models only.
