Which is better for back pain?

The Rx. It is built for chronic back and joint pain, with plush foam and Lumbar Zone quilting. The HD is firm support for heavier sleepers, not a pain-relief design.

Which is better for a heavy sleeper?

The HD. It holds up to 500 lbs and uses coils 25% stronger than standard. The Rx publishes no weight limit and is plush, so it will sag sooner under heavy weight.

Is the HD worth the extra $55?

Only if you need the higher weight capacity or firmer support. If you want pressure relief and sleep on your side, the Rx at $1,295.00 at eBay is the better buy.

The HD is likely to hold up longer for heavy sleepers because of its stronger coils and 500-lb rating. Both carry a lifetime warranty and a 365-night trial.

Can a couple with different weights use either?

The HD suits couples where one partner is heavy, since it supports up to 500 lbs. The Rx suits couples who both want a soft bed and weigh average.

Do both come with free delivery and a trial?

Yes. Both include free white-glove delivery and a 365-night sleep trial, and both are hybrids with organic cotton covers.
