Night Therapy 13" Medium-Plush Gel-Infused Memory Foam Mattress

This mattress used to be a steal, but it’s still a great deal. Guests always message me after their stay to inquire about it. https://a.co/d/0281oeD5

What? No. I’m just a regular old lady that rents out space in my home. It’s just really good mattress. A friend recommended it, and I’m just sharing it because the post was asking.

Zinus Spa Sensations 13" memory foam mattress at Walmart. Was about $350 when we got it years ago, probably has gone up in price but would still be under your budget

Ours came with an rv king but we put a regular zinus memory foam king and it fit fine. A bit longer at the feet but doable. And way more comfortable.

Skip the obsession with finding some “perfect bunk bed mattress” because most of the advice floating around is recycled marketing dressed up as safety tips. The whole thickness panic gets blown way out of proportion. Yes, you don’t want something ridiculously tall on the top bunk, but people act like anything over a few inches is suddenly dangerous. In reality, the rail height matters more than the mattress brand or type. I’ve seen parents buy super thin foam slabs thinking they’re being safe, and their kids end up sleeping horribly and waking up cranky every day. Also, durability claims are all over the place. Memory foam? People swear it sags. Innerspring? People say it pokes through. Hybrids? Supposedly the “fix,” until you read long-term complaints. Truth is, kids destroy mattresses regardless. Jumping, spills, weird sleeping positions… no material magically survives that forever. What actually made a difference in our house wasn’t chasing specs—it was rotating the mattress regularly and using a decent cover so it didn’t get wrecked early. We tried one of those popular foam ones (I think it was Zinus?) and yeah, it had that weird smell at first, but it faded. Comfort-wise, the kids didn’t care nearly as much as all these guides suggest. People overcomplicate this. Get something medium-firm, not too tall for your rails, and accept that it’s going to take a beating no matter what. That’s just how kids use beds.

I'm a skinny 150 lbs guy with scoliosis. For more than a decade, I slept on a mattress made by a small local manufacturer, a simple medium firm innerspring mattress with an Eurotop and it was fine. Also, when I go to hotels and Airbnb's, I sleep usually well and pain-free. I'm just back from France where I spent one week on a child mattress in my friend's guest bedroom and it was perfectly fine. The nightmare at home began in 2021 when I had to change my old locally made Eurotop mattress. -Cheap Zinus foam mattress bought on Amazon. It was okish once a memory foam topper was added to it, but still would give me frequent back pain that would wake me up. -Plush Wayfair mattress: way too soft, horrible violent back pain, couldn't return it, resold it, went back to the Sinus -Tuft n Needle horrible mattress: way too painfully rigid. They refunded me, made me keep it, it's now in the guest bedroom. Guests love it. Go figure. -Zinus hybrid mattress that was allegedly medium firm. It was a brick. Even with a memory topper on top of it, it was a brick. Amazon refunded me, didn't take it back, I resold it. At this point, I did all the mattress stores in my city, bought a big brand mattress that was way too soft. I couldn't return it, only exchange it. Ended up almost forcefully (nothing else was working in the store) with a Kingsdown mattress that was the softest Kingsdown mattress of the collection, but still too rigid for me. Sleeping on the side, I would wake up in horrendous pain after two hours. I have added a topper and if I sleep on my side, I'm ok until 5-6 am, where the back pain starts, but if I turn on my back during the night, I will wake up with violent pain. During Black Friday, I ordered a medium firm Silk n Snow. A brick. A mixture of granite and brick. Completely unusable. After some hassle and delays, they took it back. I once again did all the mattress stores in a radius of 150 km radius and tried everything. At my local Sleep Country, there was a heavy discount on a Casper Snow, $1000 CAD. Big mistake. That thing is waaaay too soft! Violent back pain that lasted for hours during the whole morning. I'm going to exchange it but I'm locked in to what they offer at Sleep Country. Any suggestions around that price or lower? What to look for? The firmness scale seems to mean nothing, it varies widely from one brand to the other. The softest Kinsgdown mattress is too rigid for me while a Casper that is allegedly medium first is way too soft. How to properly test the mattress in store? Which mattress could reproduce the usual hotel or Airbnb experience? In Airbnbs, it often seems to be older mattresses on older box springs. It works well for me. Why would a mattress made for children work so well for me while so many popular brand mattresses don't work at all?

Bro I bought a Zinus foam mattress almost 9 years ago and it's the best mattress I ever bought for $200 shipped.

I bought a cheap zinus foam mattress off amazon 5+ years ago and I love it. A girlfriend bought one (queen) a few years ago because they loved mine (full) so much but it was completely different. I think they might just change to whatever is cheaper at the time or something? Or the different size changes it.
