I tried an all latex mattress from SleepEZ (soft Talalay + medium dunlop + firm dunlop, their standard recommendation for the 10"), and while I loved the comfort the motion transfer was way too high and a deal breaker. So that one went back.
I’m now on an Engineered Sleep Duo Memory Plus. It’s an improvement in the motion transfer department, but somehow it just doesn’t sleep as well as the latex did. I would lie down on the latex and just wake up 7 hours later with mostly uninterrupted sleep. The Engineered Sleep has two sides for the coil-spring core, a plusher and a firmer side. The plush side sinks in a bit more and often has me waking up in the middle of the night. That doesn’t happen on the firmer side, so that’s good. But I still wake up with some shoulder pain (I’m primarily a side sleeper) and I just feel like it could be more comfortable than it is. Also doesn’t appear to be as cool as the SleepEZ latex was. The shoulder pain I think also happened on the latex mattress.
So what should I consider next for a mattress that I guess just makes me sleep like the latex did, but with zero of the motion transfer and jiggliness issues (some tests show that the Saatva Zenhaven has excellent motion transfer for a latex mattress, but it might be too expensive at $3500 for a King). Don’t really care about the materials used, as long as they’ll last a long time and will just make me sleep like excellently.
I saw the Winkbed Luxury Firm recommended on a few sites as an excellent all around mattress that would tick most if not all of my boxes. I almost ordered it, but then I saw some messages on forums that it might not be the most durable/long lasting mattress.
Also what are reputable review sites that do good objective testing? I saw NapLabs yesterday for the first time and they attempt to do repeatable tests. But no idea if they’re a reputable and truly objective review site. Consumer Reports consistently rates the Casper Dream as their best mattress, but then it doesn’t appear to be the highest quality and doesn’t seem to be very long lasting based on consumer reviews and forum messages.
