DLX

Ill use DLX as a popular example, but there are many others who do this as well, especially if you are looking at latex mattresses. Basically you have a zipper cover giving you access to the top comfort layer, so you can have different firmness and/or types of foam on each persons side.

If you specifically want online brands Engineered sleep and DLX both have a good reputation on the forums since they make mattresses that are constructed simple, they use good quality materials, and they are transparent about those materials.

Comparing them to 3Z brands, I think 3Z does a good job having good variety and giving a decent mattress for the price, but DLX and ES are both a nicer product.

DLX, Engineered Sleep, GlacierSleep, Diamond, and a few others also make very solid mattresses for people who are comfortable in this category. These are all made in the USA, use quality materials, and have the durability you’d expect from a good mattress.

DLX makes an essential two sided mattress with 1.8lb density foams, in a firm and it is well under your price point as they have an extra $100 discount off their sale price.

DLX also has some nice mattresses.

Nest Bedding and DLX will also make you split sides in the same cover. Both of them will left you switch the top comfort layer if you need to adjust.

This doesn’t sound like the typical experience that you get from DLX.

If you don’t love the idea of two separate beds and the inevitable gap in the middle, you might also check out a split firmness option like DLX. The premier hybrid is a great option in a split firmness soft/medium.

Give DLX a call or look on their website. I love my new hybrid. They work with you to make sure you get want you want. Best customer service and knowledge! I’m very happy!!
