"A good robovac is a life changer. Even a $350 basic S8. It is a great place to start. ... I promise you that you will not be disappointed by a basic S8. It will change your life even if it can't fit under every piece of furniture you own. ... My two S8s just finished vacuuming our entire house in about 46 minutes. ... While my floors were being cleaned, I sat comfortably on our patio in the cool shade with a slight breeze and composed my far too long response to you while sipping a diet soda and relaxing. ... I will have to spend about four minutes maintaining my two S8s. This will be my entire contribution to my home floor cleaning effort for today. Four minutes!"
"I got the Q5 Pro for $139. ... costs $450 less than what I paid for the S6 ... it is the best value option out there imo."
"Like 500$ these robots are currently the steal of the century ... You can get a mova p10 pro ultra (cannot remove its mops), equivalent to the l40/x40 for 500$ after a discount code"

"It's also absolutely unbreakable ... I have it since 3 years, done ton of afters, street parties, beach parties, etc, with it. Saltwater, beers, dust, sand, falling on the ground, etc, nothing broke or deteriorated it the slightest, and I am a pro for breaking anything technological."

"super comfy. ... And even me at 270lbs I can sit in my side and not bottom out (inflated a lot though)"
"definitely has improved our sleep quality a lot while camping ... boyfriend has back issues so a bad sleep set up is not really an option"
"I just put up with the pinholes and patching them on trail because I can't sleep better on any other pad. ... There's a huge difference in comfort depending on your body between the dimpled baffling of the Etherlight/Tensor and the horizontal baffling of the Xlite. ... I can't sleep on horizontal baffling despite all the good features of the Xlite. ... I'm a side sleeper and my arms and shoulders ache and/or fall asleep or go numb on the Xlite. For whatver reason I can only sleep on dimpled baffles (tensor, etherlight)"

"used for the first time at 1 degree and I was nicely warm. ... very impressed with the quality and warmth."
"It has an R value of 4.0 which has kept me warm all year round in temps down to about -5."
"how it kept us warm down to an exact 35 degree night."

"I'm not exaggerating when I say I can't imagine a pump being more effective than the one included with the lost horizon. ... It deflated the mattress to pancake flat in seconds - I don't know what better even means in this context."
"It uses an inflator bag and inflates easily/quickly."
"and has a bag system to inflate so you’re not hyper ventilating trying to blow the thing up at altitude."

"found it to be the equivalent warmth of the insulated static v plus my ccf, and even pairing the etherlight extreme with a ccf, and having it fully inflated wasn’t nearly enough for sleeping on frozen ground or snow."
"If I need more than 4 R insulation (I'm sleeping on snow most likely) I'm taking a ccf for backup because I don't want to die."
"I've only slept on it for one night with a Thinlight underneath, where it got down to 35F and I felt the cold under the pad for sure but it was fine. ... I would *never* use it without a Thinlight. ... not anywhere near as warm."

"at 183cm with some extra space for the bag with 450g of down to get the loft that tent was not enough. My head was barely touching the mesh doors of the inner, while my feet were already pushing the inner against the fly (with the tent properly tensioned!) Woke up with wet bag and cold as hell feet. Didn't bother to use it again."
"when it comes to height support, I find that Durston tends to overestimate. ... I'm 198 cm tall, and only X-Mid Pro 2+ is usable for solo use. ... I definitely wouldn’t go for the one-person X-Mid 1 if you're around 193 cm or taller."
"I had a lanshan pro 2 and it was way too small, both hair and toes got soaked from condensation."
The thermarest Neo air mats are lightweight and good quality, if a little pricey. MEC alternatives aren’t bad either. I prefer a foam/air mix pad and have been really happy with the one I have form Sea to Summit. If you want to be on the inexpensive side, look at Woods or Decathalon, but expect more weight.
I have both of these coincidentally. The plan was to take my Insulated on trips I’m packing light, and my Large S.I on trips where weight/size isn’t a factor. Both comfortable, but I personally enjoy the SI’s flat surface over the Insulated with their Air spring design. The SI has a R value of 4.1, and the insulated 4.0 so they’re basically the same for warmth. If size wasn’t a factor I’d go S.I if I had to choose one. Can’t go wrong with either one of these IMO
Exciting! I always imagined the SI would be easier to patch on the fly while camping. I also recommend one of the larger ones if you can, cuz It’s no fun having your arms fall to the ground if you’re a back sleeper. Happy camping!
sea to summit has hybrid inflatable/foam pads. I have a comfort si that is around 4 r value.
Sea to summit inflatable foam sleeping pad, believe me it's worth it, I won't waste my money on these
I’ve slept on the Comfort Plus for a couple dozen nights and just picked up the Ether Light XT Extreme after having a couple nights of bad hip pain using the comfort plus. I haven’t slept on the Ether Light yet, but it seems to be much more comfortable for side sleepers like myself. I got the regular sized Ether Light XT Extreme and have the rectangular Comfort Plus. The Ether Light is a lot smaller when packed and I’m sure the non-extreme would be even smaller yet when packed. I also think the 3” thickness of the Comfort Plus is slightly exaggerated, seems to be less than that, but that’s anecdotal. The Ether Light is markedly thicker and fellow side sleepers seem to really enjoy it. I think both are pretty nice, but based on the necessity to sleep on your side and reduce packed size/weight, would recommend the Ether Light.
The Ether Light XT was very comfortable, would definitely recommend if you’re primarily a side sleeper. If not, and you will be primarily car camping, the Comfort Plus will do well. The Ether Light’s are not on sale anymore either which is a bit of a bummer.
I had the Sea to Summit Comfort Plus SI Insulated for a while, though unfortunately, it did get punctured on my last trip. I am currently researching what to replace it with. My one qualm with the Sea to Summit was that it was relatively heavy, so I might switch it up, but I don't know if it's worth sacrificing the comfort for the weight. If I don't get the Comfort Plus again, I'll probably go with the Nemo Tensor All-Season Ultralight, which is supposed to be quite comfortable, but almost half the weight. My primary source for researching all of my backpacking gear is Outdoor Gear Lab. Their reviews and comparisons are very well done.
I have started using a Sea to Summit comfort plus si. It’s heavy for backpacking but I decided the weight penalty was worth it for better sleep. My inflatable pads all slept cold and were all noisy. It has been on closeout so likely still good deals can be had on it. (I used a coupon from REI for mine)
I have personally tried both and find the Comfort Plus SI to be the most comfortable, but sleeping pad comfort is very personal. How far along will you be? If you’ll be side sleeping you may like the thicker pad.
Ok, so for me foam makes a world of difference in comfort. Air pads feel more bouncy and I find it harder to roll over, etc, which is honestly hard enough later in pregnancy. I also found the Ether somewhat plastic feeling and crinkly sounding. The stretchy fabric on the Comfort Plus SI is super comfy and quiet. I have found the 3” enough, but I’m a back sleeper. I’ve had both the women’s version and the men’s and the women’s seemed to have denser foam, therefore a bit heavier for its size and warmer. Hope you find the perfect one for you!
I’m a side sleeper as well and I stopped using my Nemo tensor so much because of the potato chip bag noise effects heh. This past winter, I’ve used the Sea to Summit comfort plus. It is easily the most comfortable pad I’ve ever used for side sleeping. And inflates and deflates easily. Highly recommend!
I'm a big fan of the sea to summit pads. If I was buying now I'd buy the comfort plus. 6'5" 250ish side/stomach sleeper
