Hi electronicmaji,
There is more about the 3 most important parts of the “value” of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists based on suitability, durability, and all the other parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
In very general terms they certainly have some great quality/value options available but if you let me know which Dreamfoam mattress you are considering I’d be happy to make some comments about it?
This mattress has a 1.75 lb polyfoam quilting layer (and thicker polyfoam quilting layers would be less durable than thinner layers) and 2" of 100% natural Dunlop
You can see some comments about the Denver Mattress Breckenridge in post #2 here and I would be cautious because of the thicker layers of 1.8 lb convoluted polyfoam in the upper layers of the mattress which would be a less durable material than I would normally suggest in your weight range.
Once you have provided the additional information I would need I’ll be happy to make some further comments.
