King Plush Mattresses for Side Sleepers All

King mattresses measure 76" × 80" — the widest standard size, giving each partner the same personal space as a twin. They're the top choice for couples who want maximum room, families who co-sleep, and larger master bedrooms. Compare every king option below by brand, feel, and price.
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options. Shop plush models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic in memory foam, hybrid and pocket-coil builds — with free delivery across Canada. • Feel: plush is the softest of our four comfort levels (plush, medium, firm, extra firm) • Best for: side sleepers and lighter-weight sleepers — cushions shoulders and hips • Consider firmer if: you sleep on your back or stomach, are heavier, or want more support • Plush constructions: pillow-top, euro-top, plush memory foam and hybrid • Builds: memory foam, hybrid and pocket-coil • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort & Tempur-Pedic • Prices: from $224 to premium

If you sleep on your side, the right mattress cushions your shoulders and hips so your spine stays aligned and pressure points don't wake you. That's why side sleepers do best on our plush and medium-feel mattresses — especially euro-top and pillow-top, memory foam and hybrid models that contour to your curves and relieve pressure. We carry hundreds of side-sleeper-friendly options across every brand — Sealy, Serta, Beautyrest, Tempur-Pedic, iComfort, Stearns & Foster and our own NM line — from about $171 to premium. Not sure on feel? Side sleepers usually prefer softer, balanced against how much support you like. Every mattress includes a 365-night sleep trial and free delivery across Canada. • Why it matters: side sleeping concentrates weight on your shoulders and hips — you need cushioning there • Best feel for side sleepers: plush or medium (softer surfaces contour pressure points) • Best constructions: euro-top & pillow-top, memory foam and hybrid • Helps with: shoulder and hip pressure from side sleeping • Hundreds of options across every brand, from about $171 to premium • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
