Was ready to purchase one until people started mentioning overheating issues if using it with a laptop. I could use a portable laptop fan in case that happens I suppose or keep the laptop closer to the left side so the internal fan can do its thing. Need more feedback to help me decide if it’s worth purchasing.
@JT954 I’m only one person, but my experience includes several years of IT and technology consulting, as well as extensive work to repair and refurbish computers and laptops, so here’s my quick take:
For any traditional laptops that use x86 processors (Intel or AMD, basically), cooling is absolutely necessary, and would almost certainly be impeded at least in part by this sort of heat-trap. A very limited few designs have more side-oriented air intakes, and rear-facing exhausts out the back of the screen and the hinge area. Those would be in less danger, but still insulated by the completely flat and soft, cushioning surface. Not a great idea for these, particularly for longer use, or heavier computing tasks, like gaming or some other workloads.
For tablets, and other devices that are based on mobile or ARM-based architectures, such as Apple’s recent M1 or M2 designs, this is less of an issue. They rely on passive cooling (with few exceptions, like the M1 or newer MacBook Pro) and a big pillow that likes heat would be less of an immediate problem. Ideally, these devices will still dissipate heat better when their body or chassis is exposed to more air, rather than being set against a large, insulated mass. However, the lower power and heat will still be less bad.
Conclusion - Could range from acceptable (for tablets, or ARM-like devices) to very, VERY bad (for traditional, or especially powerful laptops that need to breathe). The ergonomic aspect is nice, since goodness knows we, as humans, are great at neglecting good posture practises, but similar things can be done with other solutions that promote heat dissipation, rather than smothering your device, so that it can reach high enough temperatures to throttle performance to protect itself, or possibly just cause damage. I hope that this helps inform your decision.
As a contrasting point, I use a very different style of stand, which is elevated, adjustable, and aluminum - Helps encourage airflow, and ergonomic use, while being lightweight, and travel-friendly. It may not be a perfect solution for all, but I liked it enough to have a couple in the house for my laptop, wife’s office, for an iPad/Kindle reading platform, etc. https://a.co/d/eei5Q1p
@davearnold731 Looking at the seven laptops scattered in my closets and laptop bags, of four different brands, not a single one has actual vents on the bottom. However, all of them get hot at some point across the bottom surface, and all of them have little rubber feet to space them up off of whatever surface they’re on. And there must be a reason why one of the things sold for assisting with keeping laptops running at full speed is a platform with fans in it to ventilate that bottom surface and dissipate heat. Having the laptop sitting on what amounts to a blanket would seem to be counterproductive.
