Sleep position, height, weight, body shape (waist, hips, shoulders), age, any pain or conditions, cooling needs, material preference (organic, natural, or certified-safe), and whether you want more bounce or better motion isolation.
Starts from a medium-firm evidence base, then adjusts for your specific situation — including mobility, pressure relief, and couple differences.
Three currently available options (best science match, most practical, and best value) plus a custom-made option — with the reasoning shown.
Grok’s matching is built on established evidence for spinal alignment, pressure relief, and real-world sleep needs.
Research (including the well-known medium-firm trial for low-back pain) supports medium-firm as the best default for most adults. We adjust from there.
Side sleepers generally need more shoulder and hip pressure relief. Heavier sleepers need firmer support to avoid bottoming out. Lighter sleepers often prefer a bit softer. We use height to calculate BMI, and waist, hip, and shoulder size to judge body shape: curvy hips with a narrow waist or broad shoulders need softer comfort layers or zoned support so the spine stays aligned.
Beds are for more than sleep. We factor in motion transfer for couples, responsiveness and bounce for easier movement (including sex), and overall ease of getting in and out — especially important with age or joint issues.
Extra pressure relief for arthritis or joint pain. Better lumbar support considerations for back pain. Cooling features for hot sleepers.
Answer a few questions. Grok’s rules will generate a transparent shortlist of currently available mattresses.
