Zinus Metal Platform Bed Frame with Closely Spaced Slats
Steel platform frame, closely spaced steel slats, no box spring required
Steel slats spaced for foam mattresses, which is the spacing most foam warranties require.
Best for: Foam and hybrid mattresses without a separate foundation
Watch out: Confirm the listed slat gap for the exact model and size before buying - spacing can differ between sizes in the same product line, and the warranty requirement is on you to meet.
Check price on AmazonZinus Wood Platform Bed Frame with Centre Support
Wood slat platform, centre support rail with legs, no box spring required
Ships with the centre rail and legs that queen and larger sizes actually require.
Best for: Queen and larger foam mattresses
Watch out: Wood slats vary in thickness between models; a thin slat on a wide span can still bow even when the spacing is correct.
Check price on AmazonBefore you buy
- Check the listed slat gap for your exact size. Spacing can differ between sizes in the same product line.
- Confirm centre support ships included for queen and larger.
- Subtract the mattress weight from the frame's capacity before judging headroom.
- Read your mattress warranty — it, not the frame listing, sets the requirement you must meet.
