Best Memory Foam Mattress, Expert Advice to Choose

It sounds like you’re at a crossroads between two budget-friendly Amazon favorites. Since you are a side and back sleeper dealing with stiffness and discomfort, you are effectively looking for a “Goldilocks” mattress: one that is soft enough to cushion your shoulders but supportive enough to keep your spine from sagging.

Here is a breakdown of your two choices, plus a professional recommendation that might solve your back pain more effectively.


1. The Siena 8” vs. EGOHOME

  • Siena 8” Memory Foam: This mattress is generally considered Firm. For a back sleeper, that’s great for support, but for a side sleeper, it can be problematic. An 8-inch profile often lacks the deep “comfort layers” needed to let your shoulder sink in. This can lead to the very stiffness and pressure points you’re currently battling.
  • EGOHOME Full Size: This usually has a Medium to Medium-Soft feel. While it’s more comfortable for side sleeping initially, lower-priced foams can “bottom out” or lose their resiliency quickly. If the support core isn’t strong enough, your hips will sink while you’re on your back, causing lower back strain.

2. My Recommendation: The Tempflow Original

Since you specifically mentioned struggling with back discomfort and stiffness, I highly recommend looking into the Tempflow Original. It is designed specifically to bridge the gap between “too hard” and “too soft.”

Why it fits your specific sleep style:

  • The 3-inch “Flex Comfort” Layer: Unlike the thinner layers in budget mattresses, this 3-inch high-density foam provides the deep contouring a side sleeper needs. It allows your shoulder to be cradled without hitting the hard base layer.
  • 7-inch Channeled Support Base: This provides the “Medium-Firm” feel you’re looking for. It offers a firm foundation that keeps your spine aligned when you’re on your back, preventing that “stiffness” caused by poor posture.
  • Active Cooling: Tossing and turning is often caused by heat. While Siena and EGOHOME use “passive” gel foam, Tempflow has a patented Airflow Transfer System that actually circulates air through the mattress.
  • Customization: One of the best perks is that they offer a 120-night trial with free customization. If you find it’s not quite right, they can adjust the firmness for you rather than you having to return the whole bed.
