Comfortable and quick to set up for guest or travel use, but the pump-seam leak reports mean it's not a sure bet for years of nightly use.

Overview
Serta's Never Flat raised air mattress runs two pumps: one for fast setup, a second quiet one that restores firmness through the night, built to sit 18 inches tall like a raised guest bed.
- Dual-pump Never Flat inflation system
- 18-inch raised height with 35 internal coils
- Flocked top holds sheets in place
- Includes oversized storage tote bag
Who it's for
Fits people who need a guest bed or travel mattress comfortable enough for repeated use, not just an emergency backup. Less suited to anyone wanting a mattress to survive nightly use for many years without a possible leak.
What buyers say
From Amazon customer reviews.
Owners consistently call it comfortable enough that guests don't realize it's an air mattress, and praise the auto-refill pump for keeping it firm through the night. The clear downside raised across multiple reviews is a leak developing at the seam around the pump housing, sometimes within weeks of first use and sometimes after a year or more of otherwise good service, with a few buyers replacing the mattress more than once.
Strengths and trade-offs
Drawn from this product's published specifications.
- Inflates and deflates in minutes
- 18-inch height makes it easy to get up from
- Auto top-off pump holds firmness overnight
- Three firmness settings for different uses
- Seam near the pump is a common leak point
- Real-world lifespan often under two years
- Not intended for daily long-term use per warranty
Performance notes
One pump handles rapid inflation and deflation at the turn of a dial, while a second, quieter pump runs in the background overnight, switching on automatically to top off firmness if the mattress loses air as the room cools. That auto top-off is what reviewers credit for waking up on a still-firm bed rather than a half-flat one, though it can't compensate for an actual seam leak.

Questions about the Serta ST840017
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
How long does the Serta Never Flat air mattress typically last?
Reviews vary widely, some report a leak within weeks near the pump seam, others got a year or more of regular use before any issue appeared.
Does the pump run all night?
The secondary pump stays on standby and switches on automatically only when it senses the mattress has lost firmness, rather than running continuously.
How tall is this air mattress off the floor?
It sits about 18 inches tall, close to the height of a standard bed frame, which reviewers say makes it easier to get in and out of than a typical air mattress.
