Slipstick CB674 vs Stack‑Its: Which Bed Riser Is Right

Price & Value — Stack‑Its edge ahead

Both risers land under $20, making them cheap storage upgrades. The Stack‑Its include 8 pieces for a low total cost, working out to a very low per-riser price — ideal if you need to lift multiple beds or a large sectional. The CB674’s 4‑pack costs a similar total, but each riser runs about double, still affordable but less generous per foot.

If you’re lifting a single bed, the small price difference is nothing. But buyers outfitting a guest room and a sofa often prefer the Stack‑Its’ extra pieces, which let them avoid buying a second set. If you value a simple, high‑rated riser over multiple pieces, the CB674 is still a solid buy.

Height & Adjustability — Stack‑Its win hands‑down

The CB674 locks you into a 2‑inch lift with no room to experiment. That’s fine if you measured and know 2 inches is enough, but many buyers find they want a little more or less once the bed is up. The Stack‑Its solve that: stack one piece for 1 inch, two for 2, three for 3, re‑arranging as your storage needs change.

Renters especially benefit from this flexibility. Because you don’t own the bed frame, you can’t assume the next one will have the same leg size. With Stack‑Its, you can adapt without buying new risers — a clear advantage for dorm rooms and frequent movers.

Stability & Material — CB674 delivers more peace of mind

The CB674’s steel‑reinforced core makes a real difference under heavy loads. While both risers are rated for significant weight, verified buyers report that the metal reinforcement eliminates any sense of flex or wobble, even on a king‑size bed with two sleepers. Stack‑Its, when used at full 3‑inch height, can introduce slight movement, especially on hardwood or tile.

If your bed is a heavy sleeper or you simply hate wobble, the CB674 is the safer pick. For lighter furniture like a twin bed or desk, the Stack‑Its perform adequately, but they can’t match the solidity of the unitized CB674.

Ease of Use — one piece beats a puzzle

Installation is nearly identical at first — slide each riser under a leg. But with Stack‑Its, you have to decide on height beforehand, and building the correct stack can be fussy if you’re working alone. Many buyers note that wrangling a heavy bed and aligning separate pieces is trickier than it looks; the CB674’s one‑piece design eliminates that headache.

If you’re setting up solo, the CB674 will save you time and frustration. The simpler design also means less chance of misalignment, which is a common complaint in Stack‑Its reviews when buyers stack three pieces and one shifts during placement.

Compatibility — Stack‑Its fit more leg shapes

The CB674 is designed for standard square bed legs only. That covers most modern frames, but if your bed has round or larger legs, it may not fit. Stack‑Its, by contrast, use a more forgiving design that accommodates a wider range of leg diameters, making them a safer bet for antique or non‑standard furniture.

Before buying either, measure your bed legs carefully. Both brands list dimensions on their product pages, so a quick check can prevent a return.

Rating & Reviews — CB674 has more data behind it

With 5,805 reviews and a 4.6‑star average, the CB674 enjoys a strong head‑start in buyer confidence. That’s over 1,000 more reviews than the Stack‑Its, and the slightly higher rating suggests owners are marginally more satisfied. The Stack‑Its’ 4.4‑star rating from 4,748 reviewers is still solid, but the CB674’s lead in both metrics is meaningful — especially for a product where trust matters.

In categories like bed risers, a larger review pool tends to surface hidden issues. The fact that the CB674 maintains a high rating despite more scrutiny argues for its consistency; the Stack‑Its, with fewer reviews, may see its rating drift downward as the sample grows.

Storage & Daily Life — what owners actually say

Across thousands of reviews, the most echoed praise is about space. Buyers repeatedly highlight how the CB674’s 2‑inch lift opened up storage for suitcases, bins, and boxes. The Stack‑Its reviews focus more on the ability to fine‑tune the gap — some owners need exactly 1.5 inches for a specific bin, and the adjustability lets them hit that.

On the downside, a few CB674 users note that the risers can slide on smooth floors unless held by carpet or a rubber mat. Stack‑Its, when stacked to 3 inches, occasionally produce a slight wobble that bothers sensitive sleepers. For most people, these are minor nits that don’t outweigh the benefits.

Who Should Prioritize Which

Choose the CB674 if you value stability, ease, and a proven track record above all else. It’s the set‑and‑forget option that works right out of the box and needs no adjustment — perfect for the average bed setup. If your bed is large, heavy, or you hate wobble, this is your pick.

Pick the Stack‑Its if height flexibility and piece count matter more. They’re the smart choice for renters, multi‑bed households, or anyone who isn’t sure how tall they actually need the lift. Just be prepared for a slightly more involved install and, at max height, a touch less rigidity.
