Good bargain on quality solid Queen Bed, SA?

I'm after a Queen bed and like these 2:
- Edison $ 799 @Fortywinks +delivery $50
- Pinehurst $360 @SuperAmart +delivery $77
I preferred the one @fortywinks but not happy with the price, was $749 last month now also on sale but $50 more dearer :( (they said everything cost more after July so I assumed coz of carbon tax?)
Anyone know the quality of the 2 above or can recommend me one or know where to buy cheaper?
Also thinking of getting Ergoflex - Memory Foam Mattresses $899 but concern about the over heat…is the tempur has the same problem?
Thanks in advance.
