Traditional memory foam can sleep warm, but modern gel-infused and plant-based memory foam mattresses sleep much cooler. Gel memory foam dissipates heat, while plant-based foam is more breathable. If you're a hot sleeper, choose gel or copper-infused memory foam, or consider a hybrid mattress with memory foam layers on top of breathable coils. Most South City customers who sleep hot choose gel memory foam or hybrids.

Yes! Memory foam mattresses are excellent for back pain because they contour to your body and provide proper spinal alignment. They relieve pressure points that cause pain and distribute weight evenly. Medium-firm memory foam is best for back pain—soft enough to cushion pressure points but firm enough to support your spine. Many chiropractors recommend memory foam for chronic pain sufferers.

Quality memory foam mattresses last 8-10 years with proper care. High-density foam (4+ lbs per cubic foot) lasts longer than low-density foam. Rotate your mattress every 3-6 months to prevent uneven wear. Signs you need replacement: visible sagging, loss of support, waking up sore, or mattress older than 10 years. Quality memory foam maintains its shape longer than budget foam.

Side sleepers need medium-soft (4-5) for shoulder/hip pressure relief. Back sleepers need medium-firm (6-7) for spinal support with contouring. Stomach sleepers need firm (7-8) to prevent lower back sag. Lightweight people (under 150 lbs) need softer, heavyweight people (over 230 lbs) need firmer. The best way to know is to lie down on mattresses in our showroom for 10-15 minutes.
