An adjustable bed base has three big benefits: it eases back discomfort, it can reduce snoring, and it helps relieve nighttime heartburn. It does this by lifting the head and foot of your mattress to the right angle. In a 2017 study, raising the head of the bed just 7.5 degrees cut sleep apnea events by about 32%, and the Mayo Clinic recommends a 6 to 9 inch rise for nighttime reflux. For most people, the MLILY MS200 covers snoring and reflux, while the MS300 and MS600 add massage and extra support for back comfort.
A flat bed treats every body and every night the same. An adjustable base doesn't. Below, we break down each benefit, the exact position that delivers it, and the MLILY base feature that makes it easy.
How an adjustable bed base works
An adjustable base takes the place of a box spring or foundation. Quiet motors lift two sections independently:
- The head section raises your upper body, from a gentle incline to sitting upright.
- The foot section lifts your legs and knees.
A wireless remote controls both, and preset buttons move the base to a set position with one press. Every MLILY adjustable base comes with Zero Gravity, Anti-Snore and Flat presets, at least one programmable memory setting, adjustable legs and zero-clearance compatibility for platform beds, and sets up in minutes without tools.
Benefit 1: Back comfort
The position: Zero Gravity or legs up
Raising your legs, with or without a slight head lift, reduces the arch in your lower back when you lie on your back. Zero Gravity raises both into a gentle recline that takes pressure off your lower back.
The base feature that helps
The one-touch Zero Gravity preset on every MLILY base. For more precise support, the MS600 adds lumbar adjustment, which raises or lowers the support under your lower back, plus neck tilt to fine-tune the angle of your head and neck.
More ways to adjust for back comfort:
- Upper back and neck tension: raise your head and upper body slightly while keeping your spine in a straight line.
- General soreness: raise your head and feet a little to spread your weight more evenly.
- Sitting up during the day: a fully supported incline is much easier on your back than propping yourself up on pillows.
Massage can also help you relax before sleep. The MS300 has head and foot massage, and the MS600 has tri-zone massage with three modes and three intensity levels.
Benefit 2: Less snoring
The position: Anti-Snore
A slight head lift helps keep your airway more open, so your tongue and soft tissues are less likely to fall back toward your throat.
The base feature that helps
The one-touch Anti-Snore preset. Partners can press it on the wireless remote without either of you getting out of bed. Want a custom angle? Save it to a memory setting. The MS200 and MS300 have two, and the MS600 has three.
The research: in a 2017 study published in Sleep and Breathing, researchers led by F. J. F. Souza and P. R. Genta tested head-of-bed elevation in 52 adults with obstructive sleep apnea. According to the study, a 7.5-degree incline:
- Lowered breathing interruptions (the apnea-hypopnea index) from a median of 15.7 to 10.7 events per hour, about 32% fewer.
- Raised minimum oxygen levels from 83.5% to 87%.
- Didn't disrupt the structure of participants' sleep.
The study was small and not randomized, so think of elevation as a helpful add-on, not a replacement for sleep apnea treatment.
Benefit 3: Nighttime heartburn relief
The position: upper body raised 6 to 9 inches
Lifting your whole upper body helps keep stomach acid where it belongs. The Mayo Clinic recommends raising the head of the bed by 6 to 9 inches for nighttime reflux, and notes that stacking extra pillows isn't effective because it bends you at the waist.
The base feature that helps
Independent head adjustment raises your entire upper body as one smooth incline. Set the angle once and save it to a memory button, so you're back in your reflux-friendly position with a single press every night.
Mayo Clinic also suggests waiting at least three hours after eating before lying down. Talk with your doctor about how elevation fits into your treatment plan.
Bonus: everyday comfort and convenience
The benefits don't stop at bedtime. MLILY bases also make your bed a better place to read, relax and recharge:
- TV and Lounge presets (MS200 and up) for watching shows or working on a laptop.
- USB charging ports and under-bed lighting (MS300 and MS600), so your phone is charged and you can find your way at night.
- Wall-hugging design (MS600) that keeps your nightstand within reach as the head rises.
- Split sizes, so couples can each choose their own position.

A tip from the MLILY team: spend your first week experimenting. Try Anti-Snore one night and a slightly higher angle the next, and ask your partner which night was quieter. Once you find your angle, save it to a memory button so it's always one press away.
Just so you know: this article is for general information only and isn't medical advice. An adjustable base isn't a treatment for sleep apnea, GERD or back conditions. Talk with your doctor if you have ongoing back pain, loud snoring, pauses in breathing during sleep or frequent heartburn.
Frequently asked questions
What are the benefits of an adjustable bed base?
The three biggest benefits are back comfort, less snoring and relief from nighttime heartburn. An adjustable base also makes reading, watching TV and working in bed more comfortable.
Which adjustable bed position is best for snoring?
A slight head lift, like an Anti-Snore preset. In a 2017 study led by F. J. F. Souza and P. R. Genta, a 7.5-degree incline reduced sleep apnea events by about 32% in 52 adults.
How high should I raise my bed for acid reflux?
The Mayo Clinic recommends raising the head of the bed by 6 to 9 inches. Extra pillows aren't effective, because they bend you at the waist instead of lifting your whole upper body.
Which MLILY adjustable base is best for back pain?
The MS300 adds head and foot massage to the Zero Gravity preset, and the MS600 adds lumbar adjustment, neck tilt and tri-zone massage for the most targeted support.
Do all MLILY adjustable bases have a Zero Gravity preset?
Yes. Every MLILY adjustable base includes Zero Gravity, Anti-Snore and Flat presets, a wireless remote and programmable memory.
