All you need is 2″ of soft Talalay latex, to relieve the pressure and pain at your hip and shoulder.
If you don’t mind that your half of the mattress will be 2″ higher than your husband’s half, then a twin-xl size is what to get, to minimize the cost.
However, your husband would also benefit from the topper….providing you both, with a greater depth of sleep…without sacrificing the firm support of the mattress.
Here is a link to the latex toppers. UPS delivery is free and there’s no sales tax.
If your neck pain is chronic and strong, the latex/down pillow works wonders. The other latex pillow on the same page provides a softness that can't be beat, if all you need is a comfortable pillow that will stay that way. Here is the link to those. https://themattressexpert.com/organics/organic-pillows/
