Condition:

  • This is a used unit.

  • All switches and potentiometers function as they should. This unit is 100% functional and has not faults to note.

  • Please be aware this unit is 120V. This means it MUST be used with a step-down transformer, not a travel adaptor. This amp can draw up to 300W so will need a large step-down transformer. Please check in if you are unsure as we can help you source the correct and high quality step-down.

Adjustable Support for Side Sleeping
Size: Body(Pack of 1), Color: White
The pillow is long and full, filled with shredded memory foam, and the cover feels smooth with a sturdy zipper. When I adjusted the fill, the foam shifted easily and settled without clumping, which made it simple to fine-tune the firmness. I ordered this pillow for extra joint support. In use, it stayed in place overnight and kept my hips and shoulders better aligned, especially when sleeping on my side. Memory foam naturally contours to pressure, which helps with joint support, but it can also hold a bit of warmth after several hours. The washable cover came off cleanly and went back on without stretching. It performed consistently and felt comfortable for daily sleep, and the adjustable fill and stable support explain the positive overall evaluation. This is a long pillow and takes up a lot of space, but it's comfortable and durable and easy to use. (Review is for HOMELAB Adjustable Shredded Memory Foam Body Pillow, 20x54 Long Pillow for Back)

Worth every penny
Size: Body Pillow & Pillowcase, Color: White
This thing is awesome. The pillow case is super soft too. You do need to let it unfold and air it out a bit, it’s present but not overwhelming but I think that applies to similar products. I use it when I lounge in bed. I have a king-size bed. I put it under my knees when I lay down and lay back, propped up a bit to watch movies. It’s perfect.

Better than snuggling a spouse.
Size: Body Pillow & Pillowcase, Color: White
This pillow is, can I say, 'dreamy?' It is so cushy and the cover is like buttery soft velvet. I was afraid it would be lumpy with the shredded foam filling, but it's not at all. It holds its shape and ensures a good nights' sleep. One thing, the box it came in said "Feather and Down," which almost made me send it back unopened, thinking they sent the wrong item. The pillow comes shrink-wrapped into an unbelievably small size, so there's little chance of getting it back in the box once opened. It does puff up to full size in just a matter of a couple minutes. Great purchase.

Too bulky
Size: Body Pillow & Pillowcase, Color: White
It is too big and not easy to squish or manipulate it to squish it into the shape you want it to fit to my body.
