Hybrid is the right call for guests. Coil layer in the Leesa Original Hybrid does pressure relief similar to all-foam but holds up to two sleepers without sagging into one spot. Pure foam mattresses get weird with multiple sleepers, the Nolah is fine for solo but most guests don't come solo. Trial period helps too if anyone's unsure, you've got like 100 nights to send it back.
Honestly surprised nobody mentioned Leesa yet. cross shopped Nolah vs Leesa last year for a guest room and the Leesa Original Hybrid won for me. felt basically the same on pressure relief but the coil layer in the Leesa made a real difference for guests who toss and turn. Nolah AirFoam is solid for pure side sleepers but the all foam thing means you sink into one spot all night and thats a dealbreaker if guests are actually staying multiple days. someone on Reddit just put up a [breakdown comparing two Leesa twin models](https://www.reddit.com/r/ProductProbe/comments/1stjmfi/twin_mattress_hunt_ended_with_two_different_picks/) for a guest room and a kids room which is pretty much the same situation you are describing. saved me from overthinking it when i was going back and forth. tl dr both Nolah and Leesa are in the same price tier. Leesa is on Amazon with a 120 night trial and the hybrid is worth the extra for adults. if the twin is for a kid the cheaper foam Leesa Studio is fine, dont overspend on a mattress a 6 year old is gonna use as a trampoline.
Motion isolation should be top priority. IMO a good hybrid with pocketed coils can work just as well as those zip-and-link setups. The Leesa Original Hybrid does really well for couples dealing with this exact issue. Each coil moves independently so you're not feeling every little movement.
I would actually recommend something like Leesa original hybrid or the sapira or even the Legend form Costco....it seems that these Posturepedic springs are too strong for your weight.
Not everyone is the same, you need to figure out what you prefer, soft or firm, or in between. I side sleep and prefer a more firm bed. I got the titan, and love it, I tried Leeta and the Costco brands, nova form? Not sure the Costco brands name, they were fine, but too soft for me, soft feel great at first, but for 8 hours I didn’t like it. The titan is firm, but not like hard, just not plush. Not pushing titan brand, but saying figure out what level of firmness/softness you like and find a model that claims that type of firmness/softness.
Honestly this is the best option at your price point. The only cheaper ones are the bed in the box type. Side note going down the mattress rabbit hole. If you're young it might not matter as much. But a nice mattress and good sleep is wild important. Save and get something nicer for your type sleep. Lots of things come into play for mattresses. Beyond firmness you are used to. How do you sleep, example side back, stomach. How firm are you used. Your weight and how long before it says. Are you hear sensitive, certain mattresses retain a lot of heat. We ended up with a Leesa from Costco. The return policy plus decent reviews. We went with a hybrid, so it's memory foam and springs. It was also a bed in a box.
