After writing out my top 5 list and vetting with the hubby, we decided that the best two value mattresses for us were the Foam Sweet Foam Urban Green, which is a completely customizable all-latex mattress, and the PlushBeds Heavenly Plush which is foam over latex over foam. I’ve attached my comparison list if anyone is interested (sorry the writing may be a bit small). We wound up opting for the PlushBeds mattress because they make it no risk to try it and we were a bit hesitant to jump straight into an all latex mattress without first being able to try anything all-latex in person… Foam Sweet Foam has an 18% restocking fee which seemed risky. After speaking with John at PlushBeds, the final purchase was actually the Cool Bliss gel foam mattress since I did find my hips sank too far in the softest foam mattresses we could try locally and I also occasionally wake up hot at night. The best thing is, I totally forgot we have a vacation coming up in the Toronto area and there are 3 mattress stores within 5 mi of where we’ll be staying that have all-latex mattresses! We plan on trying these while we’re there and who knows… we may wind up liking them much better. If we do, we can return the PlushBeds and get the Foam Sweet Foam without losing anything 
I would also like to share my experience shopping locally and hopefully help someone else out in the Tulsa/North OK/South KS area.
Denver Mattress (owned by Furniture Row) in Tulsa: This store was really nice. It’s large with a good selection of brands and also their own Choice brand. They have memory foam, pocket coil, air, and latex in pretty much every combination. This is the only store I found in the area that has an all latex mattress. I was not a fan of the current model which was too firm without the 3" talaylay topper and too soft with it. However, I was informed that within the next month they have a new line coming out that’s all-latex so there will probably be more selection soon! The sales guy was also friendly and knowledgeable and showed us around for about an hour with no pressure to buy.
Snow’s Mattress in Tulsa: I’m kind of surprised this one wasn’t on your list. They are a little smaller but have a good selection of major brands and also carry some smaller licesees like Eclipse and Eastland (both Sleep Designs brands). I would say this is a decent mid-range quality/value store. The sales guy was very helpful within his limits but didn’t know much about the construction of the mattresses. Unfortunately Sleep Designs out of Houston seems to either be very tight lipped in their construction or their reps are pretty clueless. Out of two contacts I got at the local manufacturer the best specs I could wheedle out of them are below:
Eclipse Calla Plush
Polyester cover
Quilting foam and FR layer
2" Convoluted memory foam
8" 660 pocket coil with 5 zone support
$795
My husband and I found this mattress very comfortable however after getting all the great info out of this forum we just didn’t feel like that was enough info to make a quality decision if it would be right for us in the long run.
Cooper Herrington Furniture in Bartlesville: This is a local mom&pop shop (or rather a mom&son shop in this case). They only carry Restonic mattresses which are manufactured in Haven KS. This is a very small store so there was not a lot of selection. They primarily carry innerspring mattresses with two all-foam choices and one pocket coil/talaylay hybrid. The owner was not very helpful and didn’t know anything about the mattresses. She mostly tried to push her preferences on us and discouraged us against the only mattress I was interested in (the talaylay hybrid) because apparently the latex sinks into the pocket coils and makes dips which seems pretty weird. The son really didn’t like when I started asking questions and also had no idea what was in the mattresses. He did finally offer to call Restonic who (second hand) was very transparent and gave the full specs of the mattress including the ILDs. The asking price for this mattress was pretty high considering similar constructions online with all natural materials go for much less. Overall I would say this store is another mid-range one and it’s unfortunate the owner only gets in mattresses she likes so there isn’t much variety.
Bob Loftis Furniture in Bartlesville: This was probably my favorite local shop. They have a great selection of brands including Golden, King Koil, and Sleep Designs in addition to all the major brands (minus S&F). Half the mattresses are foam/pocket coil hybrids and half are all foam. Unfortunately they do not have any latex because the owner found that several people had allergic reactions and decided to not stock them. The lady who helped me was also very knowledgeable and knew the construction details of all the mattresses. It’s a good thing she was there because some of them were not labeled very well (or at all) and I had no idea what the model even was. She helped look at my alignment and was also part of my decision to go with the Cool Bliss over the Heavenly Plush because she agreed that I was sinking too deep in a soft foam.
Therapedic: This was a promising looking brand (not a store) but I was unable to try any of their mattresses. I called the local manufacturer who gave me a huge list of retail outlets. Half of them were closed and the other half look super sketchy.
Meek’s Sleep Shop: This is another mom&pop shop just north of Tulsa that only sells Corsicana mattresses. I did not personally try this brand. They have inner spring, pocket coil, memory foam, and hybrids. I’m guessing this is another mid-range brand similar to Eclipse. Might be worth adding to the list…
