You should be able to get a quality mattress for 2k. I was able to get a kings sized Kingsdown for 1200, though that was after haggling. If you do your research you should be able to find something good.
I just bought a medium-firm top of the line Kingsdown spring mattress (2500ish dollars) and I couldn't be happier. It is the most comfortable mattress I've ever had. No off-gassing whatsoever and am very smell sensitive. I did a lot of research as well before settling with that one. No regrets so far.
So with the $700 one, it may have been a used model or possibly a discontinued model. I know with Kingsdown they are made to last 14-20 where as everything else is made to last 7-10 years. Kingsdown is also made with pressure relief in mind. 4k means you are probably looking at the W series at mattress warehouse. It’s got reinforced foam from head to toe (different levels of support) along with a luxury support band in the middle third of the bed for lifted lumbar relief. This isn’t to say the other beds are bad (I sleep on a series 2 medium pillow top but my mother sleeps on the medium Kingsdown in question), but Kingsdown is a cut above the rest. They have been around since 1904 and DO NOT ADVERTISE. What company do you know has successfully been around for over 100 years with no advertising? Because Mattress Warehouse has the Kingsdown, go there. Get a mattress protector with the bed and try it out. They have a comfort exchange. If after 30 days you get it, you get up to date 120 to do a switch. You get full access to what you spent the first time to go toward the second bed of equal or greater value (unlike mattress firm who takes 10-20%). So if you don’t LOVE the Kingsdown, you can upgrade to the series 3 Beautyrest or the sterns. Plus mattress warehouse gives you a price match guarantee. First year from purchase if the bed goes ANY cheaper during a big sale, you call and get a price match refund. Give them an email and you get an email every time there is a new sale. You just call and ask if it’s cheaper, when it is you get a refund. Kingsdown is also known for having amazing support with differing comfort feels. Same pizza, different topping. Their firm plush and euro top models all have the same support system with a different comfort feel. And they are also the only beds that are TESTED before leaving the factory. Every single bed goes through a machine which pressure tests it to the original spec beds that they update every now and again. If it doesn’t pass they doesn’t sell it.
Honestly I just replaced my mattress with financing at teppermans (along with a whole new bed) and I got the Kingsdown plush top mattress and it’s a dream!!!
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?
I've had my Kingsdown latex and foam mattress for at least 12 years. There is an indent where we sleep now, but it's still extremely comfortable. I bought it on a whim because it was on clearance and it's the best purchase I've ever made. It's insanely heavy and has no carry spots; it took 3 adults struggling to carry it when we moved. That's my only gripe!
