Overview
A high-density EPP foam roller for back and leg stretching, sold in 12, 18, 24 and 36 inch lengths (model G1NJ) for use in yoga, pilates, warmups and cooldowns.
Yes4All markets this as a medium firm two-layer roller, but multiple reviewers who bought it expecting a softer feel report it rolls hard with little give, closer to PVC pipe than a cushioned foam. That gap between the marketing and the actual firmness is worth knowing before buying if softness matters to you.
- Two-layer high-density EPP construction
- Available in 12, 18, 24 and 36 inch lengths
- Built for stretching, warmups and cooldowns
- Lightweight enough to move between home and gym
Who it's for
Suits people specifically wanting a firm roller for deep tissue work or physical-therapy-directed back and shoulder rolling. Not a fit for buyers expecting a plush, gentle roller, since several reviewers found it too hard for tender areas.
What buyers say
From Amazon customer reviews.
Several reviewers were surprised at how hard the roller feels despite being described as medium firm or soft, comparing it to PVC pipe with almost no give, though some kept it anyway because it worked well for back pain once they adjusted. Others specifically wanted that firmness and praised it for targeted shoulder blade and lower back pressure, and one taller reviewer recommended sizing up to the 36 inch for better coverage.
Strengths and trade-offs
Drawn from this product's published specifications.
- Holds shape without breaking down over time
- Effective for targeted back and shoulder pressure
- Available in four lengths for different uses
- Noticeably harder than the softer description implies
- Little give, which reviewers found painful on sensitive spots
- Larger sizes are less practical to travel with
Performance notes
The two-layer EPP construction is built to resist breaking down or losing shape over repeated use, and its firmness comes from that density rather than a plush outer layer. Reviewers used the length options differently: shorter sizes work fine for targeted spots, but taller users found the 36 inch better suited to full-back rolling than the 12 inch.

Questions about the Yes4All G1NJ
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Is this roller soft or firm?
Yes4All positions it as medium firm, but reviewers consistently describe it as hard with very little give.
What lengths are available?
12, 18, 24 and 36 inch versions of the G1NJ roller.
Which length should a taller person choose?
One reviewer at 5'4" recommended the 36 inch for anyone 5'5" or taller, since the 12 inch felt short for full-back use.
