Casper Adjustable Base Max for $2,495: This adjustable bed base can raise your feet or head with a simple remote control, offers four-zone massage, and allows different positions for each side if you have a split mattress. The main problem with the Casper Adjustable Base Max (7/10, WIRED Recommends) is the high price, though you can get more basic versions for less.

Sleepme Dock Pro for $1,149: The Dock Pro from Sleepme combines a Chilisleep pad for your bed with a large, square water-pumping unit that controls the temperature and pumps water through the pipes in the mattress topper. It works well but is noisier and less comfortable than the Eight Sleep cover above. Sleepme+ membership is required for insights and automatic temperature adjustments, but it’s expensive ($20 per month).

Govee Star Projector for $180: I expected to love this multifunctional sleep gadget that combines a planetarium with a Bluetooth speaker, but the projection and sound quality were disappointing, and it can’t match our Sega Toys pick above. It does double as colored mood lighting, offers several options via Govee’s app, and works with Alexa and Google Assistant, but you can do better.

Loftie Clock for $150: The most interesting feature of the Loftie Clock (7/10, WIRED Review), according to WIRED reviewer Nena Farrell, is that it can create personalized, AI-generated bedtime stories. She also liked the cute design, beautiful soundscapes, and customizable two-phase alarm but felt it was expensive, especially with the Loftie+ membership ($5/month) on top.

Somnox 2 for $599: Offering all the same features as the original in a more compact package with better battery life and an improved speaker, the Somnox 2 (6/10, WIRED Review) can help you drift off. The addition of Bluetooth streaming (iOS only for now) to listen to your own choice of content is also welcome, but this gadget is simply too expensive.

Loop Quiet for $28: These top our Best Earplugs guide for sleep. They can reduce noise by up to 27 decibels, they’re made from comfortable soft silicone, and they stay in place through the night.

MindLax Sleeping Mat for $499: This padded mat has built-in speakers and plays weird mixed soundscapes designed to relax you. It connects to an app on your phone using Bluetooth, and you can feel the sound vibrate through your body. While I found it pleasant to use, I’m not convinced it had any real impact on my time to fall asleep, sleep duration, or sleep quality compared to just lying down listening to sounds on a regular speaker. It is far too expensive, the app is basic, and the website makes suspect claims about its abilities and the science behind it.

Sensate 2 for $349: This odd device is like a large vibrating pebble that you rest on your chest for brief relaxation sessions (between 10 and 30 minutes). The makers claim that the vibrations can help tone your vagus nerve to improve your heart rate variability (HRV). I’m dubious, and it seems very expensive for what it is, but the vibrations, guided controlled breathing, and original soundscapes are very relaxing.

Ice Cube Cooling Pillow for $90: A blocky, firm memory foam pillow with a cooling material. It only works if you sleep on your side, and you can’t comfortably slide your arm under it. Although I did enjoy the cool feel, and it stayed fairly cold through the night, I prefer a softer pillow. I also think it’s pricey for what it is, but my eldest has pinched it and really likes it.

Jabees Serenity Sleep Mask for $40: While the combination of Bluetooth earbuds with a sleep mask is a smart idea, this mask is too bulky for me, and I found the earbuds uncomfortable. Your mileage may vary. The audio quality is just OK, and it’s easy to stream music, podcasts, or relaxing sounds to the tiny earbuds. The thick mask blocks light effectively. It is also comparatively cheap for a sleep gadget.

SleepPhones for $100: If you find earbuds uncomfortable or prefer to sleep on your side, this fleecy fabric headband with tiny speakers inside could be the answer. You connect via Bluetooth to stream your choice of music, podcasts, or soothing sounds. The headband is machine washable, and hardly any sound escapes to bother a snoozing partner. On the downside, the control unit shifts around and is not comfortable for back sleepers, there’s no indication of remaining battery life, and the overall quality is lacking for the price.

Morphee for $100: A lovely clockwork wooden music box design makes this a desirable bedside device, and it offers various sounds and meditations. The child version looks like a super cute wooden radio. Both are pricey, and we don’t like the Micro USB port for charging or the limited 20-minute time on sleep sounds.

Embr Wave 2 for $249: This wrist-worn device can help you deal with feelings of cold or warmth. It is recommended for relief from hot flashes but can supposedly help you sleep better as well. It is comfortable but also chunky, so not ideal for wearing to bed. It did not have much impact on my sleep quality.
