Adjustable Memory Foam Back Cushion & Waist Pillow Set – Japanese Style Lumbar Support for Office Chairs & Sofas
Looking for a back cushion and waist pillow set that supports both your lumbar spine and mid-back in one coordinated system? This Japanese-style memory foam cushion set includes a large back cushion (40x50x14cm) and a smaller waist pillow (22x12x5cm) — designed to work together to fill the gap between your back and the chair, supporting the natural S-curve of the spine from the waist up. Memory foam filling, soft cotton splicing cover, and a clean black-grey colourway that suits any office or home setting. Explore more ergonomic essentials in our Office Accessories collection and Health and Wellness collection.
Key Features
Product Specifications
The two-piece design is what sets this back cushion and waist pillow set apart from single lumbar pads. The large cushion supports the full back surface against the chair, while the smaller waist pillow can be positioned precisely at the lumbar curve — filling the gap that most office chairs leave unsupported. Together, they create a layered support system that keeps the spine in a neutral position throughout the workday.
The memory foam filling in both pieces responds to the weight and warmth of your body — softening and contouring to your back’s unique shape within minutes of sitting down. Unlike standard foam or polyester cushions that compress unevenly and lose their shape, memory cotton maintains its support profile session after session. The cotton splicing cover adds a layer of breathability that prevents the heat build-up common with synthetic-covered cushions.
Who This Is For
FAQ
What is the difference between this and a single lumbar cushion?
A single lumbar cushion supports only the lower back. This two-piece set includes a large back cushion that supports the full back surface plus a smaller waist pillow that targets the lumbar curve specifically — giving you layered, adjustable support across a wider area of the spine.
How do the two pieces work together?
The large cushion (40x50x14cm) sits against the chair back to provide a soft, supportive surface for the full back. The smaller waist pillow (22x12x5cm) is positioned at the lumbar region — either between the large cushion and your back, or independently at the waist — to fill the lumbar gap and maintain the spine’s natural inward curve.
Is the cover removable for washing?
The cover is made from cotton splicing fabric. Check the product for a removable cover zip before washing. If removable, hand wash or machine wash on a gentle cycle. Do not wash the memory foam core — spot clean only.
Will it fit my chair?
The large cushion at 40x50x14cm fits most standard office chairs and sofas. The waist pillow at 22x12x5cm is compact enough to position precisely regardless of chair size. Both pieces can be used independently or together depending on your chair dimensions and support needs.
What are the shipping options?
We ship worldwide with standard and expedited options available at checkout. Delivery times vary by destination — see checkout for your estimated arrival.
