Hate my Tempur Rhapsody, replacing with Aireloom or Prana

Hi FAUguy,

The other frame I was looking at (which I’d have to order online since Mattress Firm doesn’t sell it) is the Knickerbocker Monster, which is 80" in length, but has a 7th support in the center.

When my friend comes over today or tomorrow to help me assemble the latex mattress, I’ll point it out to him and see what he thinks.
As of now, if I sit on the bottom end of the foundation, the top tips up.

This is less likely to be an issue when the mattress is on top of your foundation and frame but the knickerbocker foundation is certainly a very strong bedframe that is longer and has a support leg closer to the end of the mattress which would reduce the chance ot tipping when you sit on the end. Post #10 here also has more information about choosing a steel bedframe and some of them would also be similar as well with a support leg closer to the end of the mattress.

Ok.
My friend showed up a little but ago and we were able to assemble the latex mattress on top of the foundation.
It took about 30 min, including getting all the packing staples out of the boxes.
I have one side as S/M/F and the other side as S/M/M. With the latex on there, it does not tip.
Trying both sides for 10 min, the SMM feels a bit better to me, but I’ll be trying both sides out over the next few weeks.
Either way, it’s still more comfortable than the Tempur Rhapsody that was returned.
