Sea Soother Sound Machine

The Sea Soother helps baby fall asleep fast and stay asleep longer in an adorable and kid-friendly fish shape! The multi-sound white noise machine for baby minimizes sleep disruption from the outside world that can wake or disrupt your child. It creates a constant, soothing sound that helps lull your baby to sleep by mimicking the sound of the womb. Once baby is asleep, white noise works throughout the night (or nap) to drown out the random noises that can disrupt precious sleep. The Sea Soother plays four soothing sounds that help baby fall asleep and stay asleep longer. The multi-sound machine is housed in a whimsical fish shape in a cheerful blue color that will appeal to children of all ages. This perfectly portable baby white noise machine helps you take the familiar and comforting sleep sound everywhere you go in a playful, child-centric fish design. Includes an oversized baby-safe clip for easy hanging in nursery, on doorknobs, or in the car. It is battery-operated and requires 3 AA batteries. (Batteries not included)

  • EFFECTIVELY MASKS NOISE: Beloved by generations since 1962, Yogasleep is the trusted leader in white noise machines and created our signature sound – the soothing ambient sounds of rushing air. The Sea Soother gives you the Yogasleep sound in a whimsical, kid-friendly shape and masks sounds that may disturb or distract for improved sleep and soothing.
  • FOUR SOOTHING SOUNDS: Choose from 4 curated sleep sounds that help baby fall asleep and stay asleep longer. Sound options include shushing, womb sounds, a lullaby, and our signature fan-based Dohm sound.
  • LIGHTWEIGHT & PERFECTLY PORTABLE: The Sea Soother fits easily in a diaper bag, backpack or tote, and comes with a durable, oversized baby-safe clip to easily hang on a stroller, baby carrier, or doorknob.
  • AUTO-OFF SLEEP TIMER: Play continuously or set the optional auto-off sleep timers with two settings (30-minute and 60-minute) tailored for nap schedules. Powered by 3 AA batteries. (Batteries not included)
  • FUN SHAPE & CHILD-SAFE: The Sea Soother’s adorable fish shape will delight children of all ages. It has undergone rigorous testing following toy industry standards and is child-safe.

    give sleep a chance

    Try any sound machine or mattress for 101 days.  If you don't Love it with a capital "L," we'll take it back.

    Great tools for great sleep! That's our promise to you.

    A sound machine or mattress is more than simply a bedroom commodity – it creates both a system and a sanctuary for serious sleep. Used consistently, a good sound machine becomes an easy but important part of your pre-sleep routine. Its soothing sound promotes relaxation before bedtime and with time, actually becomes a cue for sleep. Once you fall asleep, the constant sound created by the machine effectively masks noises all night long, so you sleep more deeply than you ever thought possible, and wake up feeling more rested and restored.

    Skeptical? You're not alone. But we've been making sound machines since 1962, and our customers say things like "Love, love love!!" and "this thing changed my life" -- and 95% still use their machines for years and even decades after purchase. That says it better than we ever could. :)

    So, we invite you to try it for yourself. Just purchase a machine or mattress on our website, and if you find that our sound machines are just not for you, no loss – we'll refund your money completely and pay for the machine's return.

    Here's how it works:

    1. Use your sound machine or mattress for the next 101 days. *Please note that it may take a week or two to get used to using your sleep product – don't give up!* Consistency is key, here, and it takes some time (an average of 66 days, say scientists) for the cue to form and become helpful. That's why we ask that you give it the full 101 days. Be sure to use your sound machine even (or especially) when you travel. You'll likely find that having a familiar sound environment is comforting in a new place, and those noise masking capabilities often come in handy, too! 

    We do require that you give your body a minimum of 30 days to adjust to your new Marpac mattress.

    2. Let turning on your sound machine become the first step of your sleep routine. Its sound will come to signal the brain that it is "time for sleep," much like a pre-bedtime meditation session... but easier. (Some people even put their sound machines on timers to act as "reverse alarm clocks," reminding them that it is time for bed.) 

    3. That's it! If you don't feel like your sleep has improved – like you're sleeping longer, deeper, and better – at the end of 101 days, just contact us for a pre-paid return label. No hassle, we promise, though we may request a little information just so we can learn and improve. (Please note: at this time, we can only extend this offer to purchases made through our website.)

    Any questions? PLEASE contact us. We're here to help.

    (If you're using the machine just for sound masking purposes while awake, don't worry - the same promise applies - if our sound machine hasn't helped resolve your aural annoyances after 101 days, we'll take it back.)

    Marpac wants to help you love the way you sleep, love the way you feel, and love the way you live – every single day.
