Oak Tree Mobility, a specialty chair and bed supplier headquartered in Bristol, England, is introducing technology to its product line developed by Abingdon, England-based sleep enhancement technology company Cambridge Sleep Sciences.
According to a news release, SoundAsleep uses two speakers built into Oak Tree Mobility’s adjustable beds and rise-and-recline chairs to play structured, low-frequency soundwave patterns that help retrain the brain and support natural, healthy sleep. The technology, based on auditory neuromodulation, synchronizes waveforms with the brain’s slow-wave activity during deep sleep to promote stable and consistent sleep cycles. In an independent study of people with insomnia, 92% reported improved sleep, with participants gaining an average of 155 minutes of sleep and waking 55% less often. A second study, presented at World Sleep Congress 2025, found users fell asleep 40% faster, spent 51 fewer minutes awake and reported improved sleep quality.
“What’s particularly exciting is that research shows certain types of acoustic stimulation can strengthen this natural rhythm and boost memory,” said sleep expert and neurophysiologist Dr Nerina Ramlakhan. “A 2013 study found that playing sounds in sync with the brain’s slow oscillations enhanced both sleep and memory consolidation, while a similar 2017 study found an overnight improvement in memory recall among older adults. In other words, when carefully formulated ‘sleep sounds’ are used to support natural brain rhythms during sleep, it not only helps you drift off, but actively supports memory and cognitive health.”
Oak Tree Mobility has integrated Cambridge Sleep Sciences’ SoundAsleep technology into its adjustable beds and rise-and-recline chairs, with embedded speakers that play sleep sounds designed to support natural brainwaves created during healthy sleep. The system features four programs — Deep Sleep, Easy Sleep, Fall Asleep and Power Nap — with optional alarms, all controlled via a dedicated smartphone app. Unlike headphones, Bluetooth speakers or phone-based apps, the embedded speakers deliver adjustable, disruption-free sound, providing an external pacing mechanism to guide users through the four stages of restorative rest in a way generic playlists can’t match, the news release said.
“We’re thrilled to introduce SoundAsleep, making us the first U.K. retailer to exclusively offer Cambridge Sleep Sciences’ SleepEngine technology built into our beds and chairs,” said Tom Powell, co-founder of Oak Tree Mobility. “Like with all our furniture products, customers will soon have the opportunity to try SoundAsleep with our free home demo service.”
“We are delighted to partner exclusively with Oak Tree Mobility, the U.K.’s leading mobility specialist, to bring our patented SleepEngine technology into their handcrafted chairs and beds,” said Adam Rostom, CEO of Cambridge Sleep Sciences. “By embedding our scientifically developed audio neuromodulation system into furniture that is custom-made to support independence and comfort, we ensure that enhanced sleep becomes an intrinsic part of everyday living. Oak Tree Mobility customers can now benefit from deeper, more restorative rest delivered seamlessly through their trusted, British-made mobility products.”
